I’ve also had good success with this one which has flexible welding probes which allow you to reach farther and get to the middle of a battery to make repairs. With my welder in the video above I have to do one row at a time as I build the battery since it doesn’t have the long flexible arms. Both methods work, it just depends on which you prefer.

$200 is on the low end of what is possible. If this is just a proof of concept, finding some used batteries and building a custom friction drive using an old DC motor will likely be a good option. Look up “friction drive ebike” and you’ll find many examples.

Hi Bert! great question, you definitely can “lace in” a hub motor to work with a fat wheel… but that’s a lot of work and given the larger diameter and heavier tire you won’t get the same efficiency and might need a larger, heavier motor. In my opinion, a mid-drive can be a great solution to this and a company called E-Rad offers an excellent modification option specifically for fat bikes. You can choose the motor and battery size you want then specify the bottom bracket size and bam! You’ve got everything you need to do it yourself. Alternatively, you could buy a pre-built fat ebike and go for something affordable like the RadRover.

Hi William! I’m going to do a bit of guesswork here based on what I hear and what I have experienced myself. The first thing you can do is to store and charge the battery inside. This will keep the cells warm and help them deliver greater range than if they were very cold to start. The second thing you can do is use mostly pedal assist to help the bike. Your 65 km ride is no joke… that’s a long way to go. Given your moderate weight of 160 lbs and obvious fitness level from riding a regular bike that far I think you’d enjoy the Surface 604 Element but you will have to pedal to make it all the way… If you tried to use throttle only and the battery is cold I bet you’d only get 10 miles (~16 km). You could order a second battery but that increases your weight and is inconvenient. Keep the battery warm, use pedal assist and if you are really needing a long-range electric fat tire bike then consider the Felt OUTFITTER. I realize it’s much more expensive but you will get MUCH better range and power… though you will not get a throttle mode. This is the most affordable Bosch powered fat e-bike I know of right now… if you want to improve comfort you can add the front suspension fork aftermarket or go for the Haibike XDURO Fatsix which has it pre-installed 🙂

Hello Court, Great information! I survive by involving in technology then no worries understand the concepts and fixing the stuff. I have spent a good deal of my time researching e-bikes in past as well fixed some e bicycles for friends for fun. Hope you could give me a hint on hub motors with lower prices but reliable machines. This is in order to support some low income crowd in Africa. What do you think about the Chinese parts? Any recommendation?

Another thing to note is that the GNG never really had serious issues. Only people that ran custom high-wattage batteries for e bikes caused parts to fail. Now that the GNG is upgraded, I’d be a fool not to try it first, especially since I’m not overvolting the unit. At $336.80 it’s a steal.

Hi Lalith, cool name you have! If you are buying a high volume of electric bike motors and batteries, then you could probably buy direct from China and maybe use a website like Alibaba. However, if you need a small or medium number, maybe you could research a company like Clean Republic. I reviewed their affordable Hill Topper kit a while back and thought it was good. If you are buying for Africa, it might be easiest to source parts in Africa or find a wholesaler in China that can ship there vs. going from China to the US and then Africa. I hope this helps you! Be careful if you are planning to buy and then fly with products like this because high capacity Lithium-ion batteries are not usually allowed.

Hi Vincent! In my opinion, there are a whole bunch of great possibilities out there. Luna has high powered stuff and the BBSHD worked great for me when reviewing a Lectric Cycles conversion a year back (using their e-RAD kit). Of course I also like BionX but the stuff is more expensive and proprietary. I’m doing less conversions these days (at least review wise) so I’m a bit behind on the category. For me, the frame makes a big difference and depending on what sort of terrain I’m encountering I’ll lean towards hubs for smooth and zippy feel or mid-drive for better climbing with the understanding that it might wear my drivetrain down, especially without shift sensing. That’s one area where e-RAD and maybe Luna now too, have some good options and accessories.

Hi Court, I have recently purchased a new adult tricycle with the intention of converting it to an electric motor. I am feeling a bit overwhelmed with all the different motor options and configurations available. I want something that will provide me with enough power to get up to speed, and have a long ride time. I have seen YouTube videos where they have linked multiple batteries to get extended ride time. What are your recommendations to get a long ride, with the power for a tricycle and a big rider?

I’ve been building electric bicycles for nearly a decade now. A few years ago I started this website as a place to freely share a lot of the knowledge I’ve accumulated over the years. One of the questions I get asked most often is about recommendations for specific parts.

Derby Cycles, Kalkhoff and Focus’s parent company, has been hard at work for the past years optimizing the design of their flagship product: the Impulse motor system. Learning from Impulse 1.0, which was introduced in 2012 and is in active service on over 150,000 ebikes around the world, Impulse 2.0 is a next-generation drive that offers better performance, quieter operation and some really bright new ideas to make what was already one of the best drive systems on the market even better. In 2015, Derby Cycles introduced the next iteration of the Impulse system, the Impulse Evo drive.

Thanks for your reply. I am 190 lb. and 6 feet. I want to do mostly road work with some hills. I also want to do gravel trails made from old rail lines and so not really “off road” but not asphalt either. I love speed and acceleration and the ability to go far (even have a second battery on the rack to change out if needed? ). I am not a long time experienced bike guy and don’t like the totally bent over road bike ride. But can go from a somewhat lean forward and exercise ride to maybe putting on “after market” handle bars that allow for a more upright cruise ride as an option with my wife. Does this help? Also looking for an electric recumbent for my wife. c

Introduced in the summer of 2014 by the company Sachsen, the large diameter of this kit is to make up for the lack of internal gears that other similar kits use. It provides 250W, and due to being direct drive, it should likely be very quiet. Thanks to ES member Miles (from the UK) for the link.

Thanks for reaching out, I’ll contact you via email. To answer your question, I’ve got a lot of experience buying from other North American ebike vendors but Luna was created less than a year ago – after I had already moved to Tel Aviv. Most of your ebike parts wouldn’t pass customs here so I simply haven’t had the chance to review your parts. This is definitely not an exhaustive list – it’s simply a list of the parts that I’ve used and found to be of good quality and price. You have good prices, but since I haven’t used your parts yet I can’t really write about their quality. In the future if I’m back stateside then I hope to get a chance to use your parts. Until then I’ve been reading some good things about your stuff on electricbike-blog.com!

Toll: I’ve actually seen a wide variety of people switching to ebikes for many different reasons. A large group consists of college students and young professionals, especially those living in cities, who use ebikes as an alternative to buying a car or relying on public transportation. The main benefits for this group include being able to commute on their own schedule, not paying for a car, insurance, parking or a yearly bus pass, and being able to beat traffic in crowded cities. I also see a lot of eco-conscious adults in cities and suburbs who use an ebike as a second vehicle, allowing them to leave their car in the garage for many of their ‘around the town’ trips that don’t really require a 3,000lb gas guzzling machine. Lastly, there are many people who would like to get into cycling, but due to their age or previous injuries, haven’t been able to succeed. With an ebike, they can get back on two wheels and have total control over how much they are pedaling and how much the motor is assisting them.

I bought a 2015 GNG mid drive, and the clutch in the crankset freewheel stopped working within a week with barely any riding at all, and I wasn’t even pedaling that hard. Pedaling now does nothing. I emailed GNG, and they told me to disassemble the clutch, and that would fix it. Anyone else have this problem?

Hi Jeff! The three companies that come to mind for me are Electric Bike Outfitters out of Denver Colorado, Dillenger out of Australia (but also sell in the USA) and possibly Luna Cycles out of California. I hope this helps point you in the right direction. You can also ask around in the kits section of the EBR Forums here.

A common electric bicycle setup is a 36V (volt) battery and a 15A (amp) controller. Wattage is just voltage multiplied by current, so 36 volts x 15 amps = 540 watts. In this case, we are looking at an ebike of approximately 500 watts. Do the math just like this on any electric bicycle to determine just how much power that specific ebike is capable of delivering.

I am trying to decide if I need a 350 watt hub motor for a bike conversion or would a 500 watt hub motor be better. I weigh almost 230 lbs but live where there are minimal hills. My husband would be doing the conversion with an all inclusive kit. Does a person’s weight have anything to do with what size motor you buy?

RPM = Revolutions per minute. The RPM’s given for a specific hub motor will be the maximum no load operating RPM. Higher RPM translate into more speed and less torque. Lower RPM is less speed and more torque. Conversely a small diameter rim will require a higher RPM motor to achieve the same travel speed as a larger diameter wheel.

The Semcon “smart engine” prototype relies on a decidedly low-tech method of getting the power to the wheel, namely friction, with a rear-facing 150W electric drive attachment secured to the seat tube that helps to spin the rear wheel. Also attached to the seat tube, although this time facing into the front triangle of the frame, is a removable battery pack, which Semcon didn’t specify the range of. According to the company, the electric drive system includes a “small computer” that could foreseeably run anti-theft or tracking applications, and the ‘smart’ engine adjusts its output to match the rider’s pedaling, actively assisting the cyclist at speeds between 7 and 25 kmh. Semcon says the device weighs in at just a bit more than a kilogram (1102g), but doesn’t state specifically whether or not that includes the weight of the battery.

It is always a good idea to stock up on fresh replacement batteries for your electric bike or scooter. You can find batteries, tubes, tires and a series of other generic parts standard for any bike or scooter at NYCeWheels.

Hi Miran! The Pulsar 250 watt hub motor sounds decent, for your short commute it could work fine and in my opinion front mounted hub motors are alright for basic city riding. They can change the steering dynamic and handling a bit but with a small motor like the one you shared I don’t think it would be a big deal. I really like the Bafang mid-drive but that will be very fast, powerful and possibly illegal where you live. Also, it might be difficult to install compared to the front kit. Here is one I reviewed that might be similar to your Pulsar: https://electricbikereview.com/clean-republic/hill-topper/

The Panasonic mid-drive motor is a remarkable bit of engineering. The basic motor design has stayed the same since the early 90s, when Yamaha and Panasonic began building drive systems for pedal assist electric bicycles. What has changed dramatically is the battery technology, which has allowed the Panasonic drive, which since the beginning was extremely reliable, to get better and better, offering riders more power and better range per charge. Today Panasonic remains a top-tier electric bicycle drive manufacturer being spec’d on a wide range of bikes from companies such as Kalkhoff, Focus, Raleigh, KTM, Helkama, and BH Easy Emotion.

“bicycle battery motor kit -e bikes kits”

I have a Stromer ST1 and I just got my wife the Optibike Pioneer allroad. We both are short (5’6″ and 5’4″, 150 pounds and 100 pounds) but we pull our sons in the Weehoo Trailer. So that adds another 60 pounds. We have very steep hills in our area. We just took our first ride with the optibike and it feels like it has about 1/2 the power on the steep hills as the Stromer. I thought the mid motor would do better on hills (optibike is 500W mid mount, stomer is 600W rear hub). Can you help me understand this and help with a better option for more power? Thanks! Oh, and I should add. We want peddle assist and throttle modes.

I’m back! Hi again Micah, So now I have a bigger question and really hoping I might hear back from you. I got a great deal on two Vpower lithium ion 48 volt 10 ah battery packs and need to know once inside, where to make the parallel connections to get the increases I’m hoping for. The only other question would be how to charge…to disonnect and charge separately, they each come with 6amp chargers, or charge them in parallel. I would be happy to to make a donation towards the sites maintenance or a few cups of java for you if there’s any way to do that, please let me know…I would be honored! Shalom!

Battery chargers are specific to both voltage and battery type. Many e-bike kits will include a charger for SLA batteries even though the kit does not include any batteries at all. TIP!  PURCHASE YOUR CHARGER FROM YOUR BATTERY DEALER.

Although hub motored bikes are convenient and readily available, the most exciting electric bikes on the planet are not hub motor bikes. Look at the 10 most expensive e-bike list for some very good examples of mid-drive bikes…with a few overly priced hub bikes thrown in. Because of their simplicity, it’s just plain wrong when manufacturers charge big bucks for hub motor bikes. Remember, anyone can build a hub motor bike…even you in your very own  garage.

Second, the 1,000W power range (when controller is unrestricted), and small size are fantastic for most potential E-bikers. Lastly, the big surprise about this drive is that it is so quiet! Also, the 500W/25A unit runs on a more affordable 36V battery for E-bikers who don’t have extreme hills.

I’m not sure that I would want a more powerful motor at this stage as I’m appreciating the extra exercise, unless I decided to trek over some of the much rougher and steeper roads inland. (which may happen in the future)

If you love bike riding but dread a steep, upcoming hill, consider converting your bicycle into a motorized, electric bike at a fraction of the cost of purchasing a moped. Choosing one of the 1000W electric bicycle motor kits from the extensive inventory on eBay and installing it on your bike can help you ride up inclines with ease. Supplement your pedaling with electric power when you just want to cruise, and enjoy the ride or rest your leg muscles for a while. Most 1000W electric bicycle motor kits feature a rear wheel and tire, and you can install it on your bike in about one hour. The speed throttle on the motor lets you control how fast you want to travel and offers the safety of a disk brake that automatically stops the motor. These battery operated bike motors give you a quiet cruising speed up to 20 mph, and they fit most BMX or touring bikes with 26-inch wheels. The Federal Electrical Bicycle Law HR727 states that as long as the bicycle’s maximum speed is 20 mph and has operating pedals, it is still just a bicycle and not a motorized vehicle.

Gotta throw some humor in here! Maybe batteries for e bike should skip electric and go for rocket powered bikes. This guy rockets to 207 mph and leaves a Ferrari in his fumes on the race track. Yes, he is absolutely crazy!

My Volto is 37 Volts/14 Ah = 514 Watts. It just copes with me on most of my riding as I’m over 100kg. What I have just been reading about, enables me to understand the juddering and complete stop of the motor on 1 or 2 places I’ve been. ( Hot weather also.) This seemingly repaired itself after a long downward gradient.

Fat E-Trike from Sun and E-BikeKit™ at Interbike 2014 Fat bikes and electric bikes were all the rage this year at interbike in Las Vegas.

[…] kit or a hub motor?  (For a relatively concise website that breaks down the differences, head here.  Maybe I should have got the rocket version?)  Anyways, by the time I thought I had the answer, […]

For instance in your response to Carlos W you say “A 100kg total (bike and rider) setup with a 250W motor and 36V battery would get 20 km/h on a 5% grade, but only 7 km/h on a 10% grade. On the 5% grade, the motor would overheat in 6.5 minutes, and on the 10% grade the motor would overheat in 1.4 minutes!”. I take the overheating figures are meant without pedal assist, so how would this scale with pedal assist? Any comment welcome.

Glad to help! It’s an interesting time for ebikes because some states and cities place restrictions but the national law is < 20 mph unassisted and < 750 watt motor = bicycle. I've been to towns where citizens have challenged the local rules and won... and the rules are rarely enforced for people who are riding responsibly. If you were concerned about legality in the event of an accident it might be worth looking into bicycle insurance.

Hundreds of hours of testing on trails, both up and back down. By thoroughly testing every aspect of this electric bike kit we can assure you that you will not be disappointed. Whether you are after speed, torque, high battery capacity or build quality – everything has been measured and tested. To top it all off, you are no longer required to have a bulky rear rack mounted battery; instead, it is an attractive slim line frame mounted battery – with the option to mount it on the included rear rack Hi Court, thanks for the reply.

Bosch, the most prevalent purveyor of motors for the electrified contingent, reigned supreme as mid-drives dominated the scene; similar versions of their motor were promulgated by Brose, Yamaha, TransX and Shimano, all promising that their system was superior. One of the more interesting mid-drives was a coaxial motor produced by eProdigy, available on a variety of their bikes. Many manufacturers distinguished their e-bikes from the others with options for very large capacity or piggy-back batteries promising ranges which were unavailable previously.

While I can’t say for sure that the battery is in fact what it claims to be, the bottle batteries due come in different lengths to allow for higher capacities.

Moving on to the next motor type, gearless hub motors deliver smooth, quiet performance and are often considered “bulletproof” by shops due to their simplicity. That said… I’ve heard of the glue inside that holds the magnets onto the canister or frame coming loose due to heat and excessive vibration. Gearless hub motors rely purely on electromagnets and may not include a freewheel mechanism because when the magnets are powered off there is very little friction or magnetic resistance to overcome. Motors that do not freewheel are called direct drive and this actually enables regeneration (the production of electricity based on repelling magnets inside the motor).

Well the first thing to know is that not all electric bicycles are created equally. Even two ebikes that both claim to be the same power or ‘wattage’ level can actually be fairly different ‘under the hood’. I’ve written specifically about the myth of the ebike wattage, but I’ll cover it briefly here.

Electric Bike Kit Compatibility: The front wheel hub motor wheels are available in 16″ to 700c size wheels. Your fork must be the standard 100mm to properly accept these electric bike kit wheels. 100mm spacing is standard spacing for front forks for most bikes. Fat bikes likely have 135mm in the front in which case a rear motor can be used. Please call us if you have a fat bike you want to convert to an electric fat bike using an electric bicycle kit.

Bikee Bike systems are made to comply to most ebike laws of different countries. But why being limited by other countries’ law? You can choose the version that better fits to your law. About this consider that not only the power matters: e-bike should have safety features and comply to speed limits and comply to restrictions about the operation mode. For instance in Europe the motor must stop working if brakes are applied. Motors without this feature are illegal. At the same time, US law states ( HR 727 ) that the motor must be less than 750W, so all the 750W motors are not legal, as a 2000W one. 

The basis of the Brose e-bike System is a steering motor produced millions of times over for cars and manufactured in accordance with the strictest automotive quality standards. This drive has been consistently developed and perfected over recent years for use in high-quality e-bikes. Production of the drive system takes place at the Brose manufacturing plant in Berlin. We are thus proud to offer our e-bike motors truly ‘Made in Germany’.

It’s all good Ben, choosing an ebike based solely on the motor is tough because the strength and design of each motor varies. I wouldn’t avoid geared hubs just because there’s more potential for wear over time. I just tested one today that is 5+ years old and still going strong (along with the battery pack). I’ll look for your post in the forums and try to help out if you provide your height, weight, terrain and desired budget 🙂

Imagine a full suspension electric mountain bike with a mid drive motor. The front and rear wheels can rebound quickly and efficiently because their mass is lower and the overall weight of the bike itself is connected to the main section of the frame making it feel fluid. When approaching a large hill, the rider can shift into a low gear providing mechanical advantage making it “easier” to pedal and climb. Just as the rider benefits in this scenario so too does the motor. While the overall speed of the bike is reduced for climbing, neither the rider, nor motor will be over exerted thanks to the gears. In this scenario the rear dropouts also endure less strain because the weight and force of the motor are spread out and connected to the major tubing of the bottom bracket.

Samsung 26F cells (2.6AH, 5.2A max) – These cells are good for lower power applications where you don’t need more than 2C discharge. I built a lot of 48V 15-ish AH packs from these cells. Great for low to medium power applications. I get most of my 26F cells here. That vendor’s prices are a little higher but I’ve worked with them a lot and know they are great quality and have good service/communication. Recently I started getting cells from here in higher quantities because the price has been better.

Hi Bert! great question, you definitely can “lace in” a hub motor to work with a fat wheel… but that’s a lot of work and given the larger diameter and heavier tire you won’t get the same efficiency and might need a larger, heavier motor. In my opinion, a mid-drive can be a great solution to this and a company called E-Rad offers an excellent modification option specifically for fat bikes. You can choose the motor and battery size you want then specify the bottom bracket size and bam! You’ve got everything you need to do it yourself. Alternatively, you could buy a pre-built fat ebike and go for something affordable like the RadRover.

I have seen as much as 8000 watts going through a traditional derailleur gear chain (see astro ebike story) with little problems as long as shifting is done with care….but that is with quality shimano components and chain.

Additionally, while the previous models had one integrated lithium-ion battery pack, the X allows you to use anywhere from one to three replaceable batteries. The range varies from 16 km (10 miles) with a single battery, up to 48 km (30 miles) with all three. A new regenerative braking feature, which is activated by pedalling backwards half a revolution, helps boost that range.

A control panel in the top of the pack lets riders do things like selecting the amount of electrical assistance, and checking how much power is left. An electronically-limited top speed of 15 mph (24 km/h) is possible in the European version, or 20 mph (32 km/h) for the US/international model. The range sits at either 25 or 50 miles (40 or 80 km), depending on which of two available battery capacities are selected. Charging time is 3-4 hours or 5-6, respectively.

Toll: The two main benefits are price and custom specifications; you can save a lot of money and get the exact speed, range, power and other parameters that you are looking for. By not buying a retail ebike, you aren’t paying for all the R&D, markup and overhead that goes into selling those bikes. Instead, you can buy the same parts online for much less than the cost of retail ebikes with those same parts. Because you are buying the parts yourself, you can cherry pick from among hundreds of different types of batteries, motors and speed controllers to get the exact specifications you are looking for.

Since the wheels are 20″, 48V would be a good option. It would probably be too fast on a 26″ trike, but the small wheel makes the gearing more appropriate. You don’t want to make an e-trike too fast as trikes get unstable at high speed. I electrified one for myself a few years ago just for fun.

I am planning to mount an electric kit (like the 8fun mid drive) on my mtb in order to go to work on bike more often. In my case it is 35km one way consisting of a mix 1/3 kinda hilly gravel roads and 2/3 bike lane. I wonder about my power requirements, yet being a newbie I am still a bit confused about the figures in this discussion, since it is not always clear if they are pertinent to “pure throttle mode” or to “pedal assist mode”. I am mostly interested in the latter.

“electric bike kit review |electric bike kit with battery”

Loved your comparisons as I’ve been thinking about an e-bike. I ride rurally with gravel roads and lots of long hills, some up to 3 miles and some steep. The plan was to take my cross bike and install a kit but not sure what brands are out and what type would work for my setup especially after watching your hill video. The other issue is durability and dealing with gravel dust. I’d hate to wreck and break something and would gravel dust ruin internal parts? Thanks!

Based on everything you wrote, I believe that both the Bosch or Brose motor system would be a good fit. I have owned one of each and appreciate their wider cadence range. You get shift sensing with Bosch but it sounds like you understand how shifting works given your nice carbon road bike… the Brose is a bit quieter and gentler feeling. Perhaps it comes down to which models appeal to you and fit your body size. I didn’t see your height there? Either motor system would be capable of moving your standard 165 lb body.

Hi Jairus, I really like the BionX D-Series for power, reduced noise and the efficiency of regenerative braking. It’s a high quality kit with throttle and pedal assist mode with a solid warranty. You could also check out the e-RAD kits but they might not work on a recumbent setup. One final option could be the Ridekick but it’s a bit noisier and may be back ordered. Recumbent riders like that one because it doubles for power and storage 😉

By offering our customers the best products possible, along with an industry leading warranty and outstanding after sales service, we have grown exponentially, from a small local business to one of the largest international manufacturers and suppliers of quality ebikes and ebike kits.

I used to own an Easy Motion Neo Jumper and would commute to work 5 to 8 miles round trip per day and never ran out of batteries. Here’s a video of what I did and it shows my commute. Hope this helps!

There was a great charger vendor from China that I used but unfortunately went out of business last year. He was a young guy and just found it hard to compete with the bigger established countries. Since then, and with his recommendations, I’ve settled on a few other vendors that I use for chargers.

In my last post I wrote about how batteries for electric scooter was introduced to E-bikes. After considering a new factory build E-bike I decided to purchase a “kit” and convert my 30+ year old Diamondback Response Sport mountain bike over to electric. I decided on the Dillinger 350 watt front hub kit with the frame-mounted 36v 10ah battery.

Hi Court and thanks for all the info. I am in Montréal and would like to know in minus 15 and minus 25 what range may i expect? I am 160 pounds and would pedal, mostly flat and asphalt with 1/3 old railroad now small gravel. I am looking at a Surface604 Element 60 pounds 3 assist levels plus throttle. Weekly i go to a secondairy house 65 km away wich i pedal in 2.75 hours on my 18 pounds summer road bike.

In response to customer questions about the display, we posted a video detailing the basic setup of the LCD during installation of the kit. You will need to adjust the settings for the motor type, wheel size, and battery voltage in order to match your specific kit.  Detailed instructions are available in the E-BikeKit manual, E-TrikeKit manual and LCD Quickstart Guide

So hub motors take the place of regular light weight hubs, connecting the wheel to the bicycle axle. As they receive electricity and spin, the bike is propelled forward and some of this energy is exerted into the frame at the dropouts. Usually the sturdiest place to mount a hub motor is in the rear wheel because these dropouts are reinforced and have four legs connecting them to the rest of the frame instead of just two on the front fork. These four arms consist of two seat stays and two chain stays.

We named the product iMortor, and it was a good start, but was limited in ability. The wheel could only be controlled via a throttle, and was only available in 26″ sizing. The sensors in the wheel were not particularly advanced, and the battery was not as efficient as it could be. Finally, the wheel weighed 18 pounds. We knew we still had work to do, and we wanted to build a version that would be street legal world wide.

The Semcon “smart engine” prototype relies on a decidedly low-tech method of getting the power to the wheel, namely friction, with a rear-facing 150W electric drive attachment secured to the seat tube that helps to spin the rear wheel. Also attached to the seat tube, although this time facing into the front triangle of the frame, is a removable battery pack, which Semcon didn’t specify the range of. According to the company, the electric drive system includes a “small computer” that could foreseeably run anti-theft or tracking applications, and the ‘smart’ engine adjusts its output to match the rider’s pedaling, actively assisting the cyclist at speeds between 7 and 25 kmh. Semcon says the device weighs in at just a bit more than a kilogram (1102g), but doesn’t state specifically whether or not that includes the weight of the battery.

The best bet is to try and locate the performance charts like these for each motor before you buy to compare. When you’re stuck with a 250W motor, there’s not a lot you can do to maximize torque though. You can aim for a lower speed motor which won’t have more torque, but you’ll feel like you have more effective torque because the motor will not heat up as much when towing as it is staying in a more efficient rpm range. Other than that, 250W are pretty much known for not being so torquey. You can always overvolt your motor (swap in a 36V battery instead of 24V or 48V instead of 36V) which will give you a boost in power and torque.

I have a Stromer ST1 and I just got my wife the Optibike Pioneer allroad. We both are short (5’6″ and 5’4″, 150 pounds and 100 pounds) but we pull our sons in the Weehoo Trailer. So that adds another 60 pounds. We have very steep hills in our area. We just took our first ride with the optibike and it feels like it has about 1/2 the power on the steep hills as the Stromer. I thought the mid motor would do better on hills (optibike is 500W mid mount, stomer is 600W rear hub). Can you help me understand this and help with a better option for more power? Thanks! Oh, and I should add. We want peddle assist and throttle modes.

THIS BIKE WOULD NOT COME CLOSE TO WHAT YOU WANT. YOU WOULD NEED A ROLLING BATTERY ON WHEELS. I have a Walmart bike with a 48 volt 1000 watt brush less motor. I use six 5000 watt 6 cell lipo batteries from Hobby King. I only charge to 4.05, and I only discharge to 3.7. even under a load. I have a little volt meter to watch the voltage so I never go below 3.7 volt, even under a load. I have two Reedy 1216-C2 chargers that can be set to max cell charge of 4.05 max per cell. Li-poly if treated right are safe enough for me. I always charge on a metal surface or inside a large pot or pan. If the battery were to catch fire there is nothing around to burn. Just nasty fumes and smoke. From my experience lipo batteries can put out a much higher current than lion, which can get me up the hill faster for less money. Six 5000 watt 6 cell lipo batteries can put out about 750 watt hours. Mine don’t because I don’t charge to 4.2 and drain down to 3.2 per cell. To get the watt hour rating (Ah × V = Wh).

One Con missing from from Rear and Front hub motors e-bikes is the frequent damage to rims (spoke pulls) due to high torque of electric motors. Also I prefer good mechanically (non hydraulic) Avid BB7’s Disc brakes easier to service and or repair on long hauls. Why disc brakes? E-bikes using a motor cause (Heat & Friction) wear and tear on Rim Walls, traditional rubber rim brakes will cause extra wear and tear possibly causing instant rim /wheel collapse, rather replace disc pads more frequently than rebuild wheels.

Our number one pick for a mid drive right now is the 48V Bafang BBS02, and for all the details, see our article, here. First of all, it can easily be installed on over 90% of the common frames available. The installation is simple enough that any average cyclist who is capable of fixing a bicycles flat tire…can install this drive by themselves.

Hi Court. Thanks for your prompt response. Based on your input and further consideration I have narrowed my selection down to three Bulls e-stream brose MTB models: Evo 3 29er, Evo 3 FS 27.5 plus, and Evo 45 FS. I selected Bulls for a variety of reasons but I have to admit I am a pushover for good looks. Bulls offers a wide range of models and there is a dealer in PA within a reasonable drive from my home in MD. Unfortunately, they do not stock any MTBs but may be getting one or two in soon I can test out. I am still on the fence with regards to a full suspension bike but I realize my back is not getting any younger and I may learn to appreciate the extra comfort on the paved and unpaved hilly roads I ride. One of the suspension seat posts you suggested would definitely help with the hardtail but these are heavy and fast riding bikes (especially the EVO 45 FS which you reviewed in February) so if comfort is of prime concern a full suspension probably is the way to go.

Since the power is being transferred through the drivetrain of the bike there can be more wear applied to the drivetrain components (chain, cogs, derailleur, etc.). The higher power systems will add significantly more wear and those components may need to be replaced on a more frequent basis.

Hi Jeffrey, I’ll do my best to answer this question based on my experience testing. Mid-drive motors get a lot of attention for being efficient because they can be empowered through gear shifting if they are setup to pull the same drivetrain as you, the rider, and the bike actually has gears. So a mid-drive on a single-speed electric bike might actually be less efficient than a hub motor because it’s transferring energy through a chain or belt before reaching the rear wheel. There several mid-drive designes out there which pull a completely separate drivetrain like this, and are therefore not as efficient as they might otherwise be but still benefit the bike design by balancing weight at the center of the frame. And so, if you have something like the Bosch Centerdrive, Yamaha, Impulse, Brose or others which pull a chain or belt and benefit from the mechanical advantage of a cassette, internally geared planetary hub or continuously variable transmission AND you actually shift appropriately… then you will generally go further, climb easier and even accelerate faster than most hub motors. Geared and gearless hub motors usually have a sweet spot for efficient operating speed RPM and that is usually translated to above 10 mph on the bike. So when you start from zero the motor is struggling and only once you’re reaching those higher speeds does the motor start to “relax” and perform optimally. I hope this helps, there are some excellent hub motor designs out there… they tend to be easier on the drivetrain and less expensive but increase unsprung weight (if the wheel is on a suspension) and can create imbalanced weight distribution compared to mid-drives.

Like the original Rubbee, this model simply clicks in and out of a mount on the bike’s seat post – that process is reportedly quicker now, taking just one second instead of the previous seven. This means the device can be taken off of the bike and carried inside to charge the battery, and to keep it from being stolen.

Yamaha’s newest entry into the electric bike market shows a lot of potential. It’s no surprise: Yamaha has been building electric bike systems for more than 20 years, has millions of systems on the road, and produces nearly 300,000 units annually.

I use heat resistant and non-conductive tape when building batteries. It’s not super strong so I don’t recommend using it in a structural application like electrical tape, but it’s a lot stickier than electrical tape so it’s perfect for cases where you need to cover exposed wires or contacts to prevent shorts, especially in an area that can get hot – like a battery.

Watts (W) = A derived unit of power or a measurement of power . I.e. 750 Watts = one horsepower. Hub motors will typically be advertised as 250watts to 1000 watts. To find the actual wattage your motor will be running at use the following formula. Volts x amperes = watts. Almost all of the motors being used in today’s e-bike kits are designed to work across a range of both volts & amps. Hence watts can be subjective number. 

I haven’t gotten to purchasing a GPS tracker, though I plan to very soon. I’m deciding between a simple one like this general purpose GPS tracker and a bicycle specific GPS tracker like this clever one hidden in the stem of the handlebars.

This element contrasts the torque generated by the motor to prevent it turning onto the bike frame. These can be anything from a flat washer with a bendable tab to a true “torque arm” consisting 3 or 4 parts. 

The second big change is that the motor now runs at 48V, making the motor both accelerate and regenerate much more efficiently and powerfully. Finally, the fit and finish of the Syno-Drive has been considered from the perspective of service. Instead of a bolt-on axle, the Syno-Drive uses a modern thru-axle for added rigidity and easy removal.

Cool! Glad I helped a little, it’s a fun journey creating something custom. I love doing the research, drawing designs and sharing ideas. If you do create a custom bike be sure to post some pictures and updates in the forum! I’m sure other people would love to see how it all turns out if you’re open to sharing 😀

For a pretty standard yet powerful 48V 1000W ebike, I like to go with a 9C-clone-style gearless motor like this one from Conhismotor, which also includes the controller, ebrakes, etc – basically everything you need except for the battery.

I don’t understand what you mean by 7.2AH/20hr batteries. Are they 7.2AH or 20AH? 7.2AH isn’t much, especially for SLA’s where you shouldn’t really discharge them more than 50% if you want long life out of them.

You charge up hills and down straightaways on your bike on a regular basis, but getting a little extra help never hurt anyone. An electric bike kit gives you that extra push you need on long hauls and up steep inclines by mechanizing the pedaling process. With electric bike conversion kits, you can take your favorite bike and adapt it rather than getting a new, pre-assembled electric bike. When selecting an electric bike kit, look for options that work well with the size and structure of your bike’s frame. You can also choose from throttle-controlled units that give you manual control of the system, models with pedal sensors that use your pedaling to turn on the system, and kits that combine both features. Also, look for electric bike kits with batteries that can mount easily onto your particular bike and suit your riding style. Both new and used kits are available via the sellers on eBay, so look through these listings and convert your bike into a motorized machine that helps you take on any terrain.

The 250-watt motor manages a top electric-assisted speed of 25 km/h (16 mph). If you go for all three batteries, however, you can opt for a 350-watt motor upgrade, which makes possible a top speed of 32 km/h (20 mph). A smartphone app is used to select how much eletrical assistance is provided.

I’m not sure I understand the question. If you run a generator off of an ebike, you’ll probably end up getting back around 75% of the energy that was stored in the battery, after efficiency losses. The second law of thermodynamics is a cruel mistress…

For instance in your response to Carlos W you say “A 100kg total (bike and rider) setup with a 250W motor and 36V battery would get 20 km/h on a 5% grade, but only 7 km/h on a 10% grade. On the 5% grade, the motor would overheat in 6.5 minutes, and on the 10% grade the motor would overheat in 1.4 minutes!”. I take the overheating figures are meant without pedal assist, so how would this scale with pedal assist? Any comment welcome.

Of course, I enjoy a sportier, faster accelerating ebike so I ride an ebike with a 48V battery and 20A controller, giving me about 1,000 watts of power to my direct drive hub motor. That’s more than I need at my weight in a flat city, but if I lived in a really hilly city, that would be a quite appropriate power level. As it stands, in my flat terrain city, 1,000W leaves me some wiggle room for strong accelerations and occasionally towing a bicycle trailer, though I generally don’t use anywhere near 1,000W for my daily driving needs.

A person riding a bike cannot usually output more than 200-250 W of power for more than a minute or so. If you use the motor only as an assist, I think that 250 W would suffice even in http://huntneqip.com terrain and for a 100 kg person. Can you please explain why my reasoning is wrong?

Also is there anyway to tell how much max amp my controller is. I am trying to do the math like you easily explained in a different page (thanks for that) to figure out the actual wattage of my bike now and if i were to switch the setup. Thanks

running 2 hubs from one controller is possible, you must make sure that the motor controller can effectively power your hubs. for example if you had 2 hub motors that were 48v and 500w each you would need a motor controller that is able to output 48v 1000w. The hubs also have to be set for the same voltage, the wattage could differ from hubs but not recommended, its best to use 2 hubs that are the same. a good controller to use is the one offered by goldenmotor (canada), it works with 24,36,48v hubs and goes up to 1000w continuous or 1500w peak the controller is also programmable, also allows for regen. also make sure your battery can handle the current draw.

A Swedish technology firm, Semcon, has developed just such a product, which can be used to turn just about any bicycle into an electric-assist bike, at an estimated cost of about €100. There’s just one hitch – it isn’t for sale. Yet. But with any luck, some forward-thinking investors will put one of the most potent motive forces in history (money) behind it, and bring a low-cost electric mobility add-on to the market.

Some mid drive systems can sense when you are going to shift the gears and they will reduce the power for a smoother shift.  There are some systems that don’t have these sensors and that can lead to abrupt shifts when the motor is applying full power.

I’ve been building electric bicycles for nearly a decade now. A few years ago I started this website as a place to freely share a lot of the knowledge I’ve accumulated over the years. One of the questions I get asked most often is about recommendations for specific parts.

There are a lot of different controllers out there and they all have their specific uses. I build a lot of medium power ebikes so I don’t need anything too fancy. For the most powerful ebikes I build, I reach for a Lyen controller or an EM3EV controller, which are comparable for quality and price. Lyen ships from the USA while EM3EV ships from China, so that may affect your decision depending which country you live closer to.

Climbing is where mid-drive motors really shine. Unlike a hub motor, this design lives at or near the bottom bracket (the point where the crank arms attach through the frame for pedaling) and drives the chain forward instead of the wheel itself. Mid drive systems benefit from many of the same mechanical drivetrain systems as the rider (the use of gears for climbing or going fast) and reduce unsprung weight. This is the optimal setup for efficiency (extending ride distance) and climbing.

Ultimately, I have a love hate relationship with mid drive systems because I appreciate their efficiency but miss some of the zip and instant gratification that hub motors offer. They are often noisier as well… Some mid drive systems can feel clunky and frustrating to shift but others are actually very satisfying to use. I’m talking about the Bosch System and similar high quality offerings which can actually sense that you’re trying to shift and gently cut the motor so you won’t strain the drivetrain. The final advantage with mid-drives is that the motor weight is located centrally on the frame in addition to being low. This is going to provide stability when riding or lifting the ebike for transport or storage. One quick downside is that the motor may be vulnerable to rocks and logs on the trail with a mid-drive because it’s not surrounded by spokes and a wheel like hub motors are. In my experience, most mid-drives are protected with some plastic or metal casing that can take a few hard hits before suffering damage.

Hi Lisa! Front hub motors can be fine, they do tend to impact steering a bit and can spin out easier but are way simpler to either install or service because they aren’t surrounded by gearing cables. The fork on most bicycles isn’t as strong as the rear dropouts (especially if there’s a suspension fork) and this is another reason why most purpose built models don’t use them. Some simple city bikes do however and you can get a good example of this with EZ Pedaler. They opted for front motors because they put geared hubs in the rear which makes shifting at standstill possible, reduces exposure to bumps if the bike tips and is generally cleaner and less likely to need tuneups (but only offers 3 gears in this case). I hope this helps you to find the perfect ebike, feel free to post in the forums if you’d like more info or some help from fellow electric bike owners 🙂

This bike only needs to get me to and from work on paved roads (and some sidewalks) and I don’t plan to ever take it on any trails but it does need to be able to handle hills. I have a local bike shop near me, but they currently don’t sell anything electric (the guy did warn me against Pedego bikes, though…saying they were not good quality. I mention that to say this: I don’t know how good any local service options are going to be for me, so simplicity and having a bike that works are important. Also, I’m on disability and don’t have much money, so price is a factor (that’s why the Flux on Indiegogo appeals to me).

A more fleshed out and finalized prototype, on which both the iMortor and the UrbanX is based. The iMortor could only be controlled via a throttle. It was exclusively available in 26″ sizing, and it weighed 18 lbs. For UrbanX, we added an entirely new, 350W motor option. We added and improved sensors for speed, motor braking, and pedal assist functionality. We increased available sizes to 6, and we reduced weight to 15 lbs. We developed our Sinus Algorithm Controlling System to improve battery efficiency, and limited speeds to road legal speeds for global regulations.

Has anyone found a battery case maker that makes cases that will fit into the main triangle of a men’s mountain bike? I find having the hub motor and rack battery in the rear makes the bike feel awful to ride.

This article first appeared in Electric Bike Report in June of 2013. Since then, we’ve made some changes to our motor selection – our Direct-Drive motors are now all High-Torque 6×9 wound, so they run slower (approximately 15mph at 36v or 20mph at 48v), and our Geared Motors have been replaced by a 500w version, (approximately 20mph at 36v or 28mph at 48v). The Direct-Drive is now our Heavy-Duty motor and the…

In fact, all the e-bikes that have a “hub-motor” ( or “hub wheel”, which is basically the electric motor inside the rear or front wheel ) are operating at one fix gear, which is usually high so that the e-bike can achieve its top speed. In these conditions the motors needs to generate a very high torque during acceleration or going uphill and that has a negative effect on all the e-bike components ( such as battery, controller, motor), reducing the e-bike autonomy.

I’ve heard that newer hub motors have heat sensors to protect the system and they automatically shut themselves off if overloaded (is that what yours is doing?) mid-drives can be a great solution if you shift properly, it makes the job a lot easier for the motor (just like it does for you pedaling) and works pretty well in my experience.

Original Equipment Manufacturer Parts (OEM) have been designed by the manufacturer to be compatible with your scooter, folding bike or electric bike. That holds true for parts made by Brompton, Tern. Bulls, Stromer, Dahon  and many other brands. Find original replacement parts for the BionX electric bicycle conversion kit, like batteries, chargers, consoles, motors and wiring. NYCeWheels sells parts for Brompton Folding Bicycles whether you need to replace a part or just want to stock up with a spare, just in case. NYCeWheels even sells some hard to find replacement parts and accessories, like those for the eBike that is no longer in production.

The basis of the Brose e-bike System is a steering motor produced millions of times over for cars and manufactured in accordance with the strictest automotive quality standards. This drive has been consistently developed and perfected over recent years for use in high-quality e-bikes. Production of the drive system takes place at the Brose manufacturing plant in Berlin. We are thus proud to offer our e-bike motors truly ‘Made in Germany’.

I have a Bafang Mid-drive motor it run at 48Volts with an 11 amp hour battery. It’s fitted to a Giant hybrid bike . To give people an idea of how reliable it is I travelled over 8000 kilometers last year without any problems. I used three rear tyres and 3 sets of Disc brake pads. I have fitted hydraulic disk brakes. At 5000k I replaced the chain and rear cluster just because I want it reliable due to the fact I often do trips in excess of 60 kilometers and don’t want to breakdown 30 kilometers from home. I also live in a very hilly area. I ride in all weather I have fitted a watt meter so I can monitor the amps left and how many watts I am using. Only once after 70 kilometers did it warn me low battery I do pedal all the time and use the motor a little bit often I think this helps me with my distance. I love riding the bike since I batteries electrical brought the bike it is saving me nearly $50.00 a week in petrol so it has paid for itself and I ‘m .much fitter and healthier.

@Charles Avent: This is an easy problem. You need to overspec your motor controller. ie: If you have a 500W motor, get a controller capable of handling 1500W. The larger controllers will have more power mosfets (the electronics actually handling the power to the motor) and more heatsinking. This shouldn’t cost you any more than about $200. People selling quality upgraded controllers will also usually advertise having replaced “no-name mosfets” with quality mosfets with a “low RDS” (ask them about this, if they don’t know don’t what RDS is don’t buy from them, if they do know they’ll be able to solve your problem).

Hi Jeff! The three companies that come to mind for me are Electric Bike Outfitters out of Denver Colorado, Dillenger out of Australia (but also sell in the USA) and possibly Luna Cycles out of California. I hope this helps point you in the right direction. You can also ask around in the kits section of the EBR Forums here.

Moving on to the next motor type, gearless hub motors deliver smooth, quiet performance and are often considered “bulletproof” by shops due to their simplicity. That said… I’ve heard of the glue inside that holds the magnets onto the canister or frame coming loose due to heat and excessive vibration. Gearless hub motors rely purely on electromagnets and may not include a freewheel mechanism because when the magnets are powered off there is very little friction or magnetic resistance to overcome. Motors that do not freewheel are called direct drive and this actually enables regeneration (the production of electricity based on repelling magnets inside the motor).

One of the biggest questions about electric bikes is “What’s the difference between motors?” and that’s because there are several different types including geared and gearless hubs, mid-drives and shaft drives. Not to mention brushed and brushless… I’m hoping this post can help to clarify the space a bit so you can focus in on finding the right ebike for your intended use.

My second question is what drive train you would recommend? I am leaning towards a mid-mount motor (Bose or Bosch) primarily for the added torque and extended range. The mid-mount systems also seem to be the trending direction for major e-bike manufacturers even for city bikes. I love the integrated look of the Bose models but appreciate the design and simplicity of the Bosch system. Since I come from a recreational road bike background, which mid-mount motor do you think would feel more natural to me the Bose or Bosch? A single front sprocket has its appeal for reduced shifting/complexity but 2X have their advantage also. Alas, a very difficult decision. Since this an expense endeavor, any insights you may have to guide me down the right path would be greatly appreciated.

I don’t actually have one of Lightning Rod’s kits, so unfortunately I can’t comment deeper right now. But I sure don’t find it valuable to just rag on the cost without examining other factors of the component quality and design. Lot’s of owners of the GNG kit went to lightning rod’s dev to purchase upgrade components because of lack of quality on the “cheap” kit.

Most of the electric wheels we’ve seen have been quite heavy – this is because they contain not only a motor, but also a battery pack and the associated electronics. That extra revolving weight makes them difficult to move if pedalling without electrical assistance, so the bike’s original unpowered wheel needs to swapped back in when using the bicycle in non-e-bike mode.

Hub motors were the first type of drive systems for bicycles to be patented and they continue to be popular today. Instead of trying to integrate a motor into the bicycle drivetrain (complimenting the gears and chain that the rider uses) hub motors stay completely separate. Electricity is run through copper wires to create electromagnets which repel traditional rare Earth magnets and create force that rotates the hub forward (and sometimes backwards). In the early days brushed motors were used because they are inexpensive and require less sophisticated control systems but the brushes wear out over time and require replacement. These days, nearly every hub motor (geared or gearless is brushess and uses direct current DC).

This drive is new and is VERY similar to the recently popular Bafang BBS02. This pic was taken at the April 2014 bicycle show in Shanghai, China. Pic thanks to ES member d8veh. On Alibaba, these have been seen being sold under the “BTN” label (Back To Nature). Thanks to the German pedelecforum.de member “airbox” for the link. Danke Schoen!

This kit is a converted geared hub-motor that is listed in the GNG catalog as a 36V/350W, or…as a 48V/400W. Its a great choice for a street commuter, see the details in our article about this drive, here. It’s just as easy to install as the BBS02, and..although it has less power capability than the BBS02, it also costs less. It makes the same amount of gear noise as any common geared hub-motor.

At the Interbike 2015 convention, Bafang introduced a larger version of their popular mid drive, and the “HD” stands for “Heavy Duty“. The bottom bracket on the standard HD drive is 100mm wide, so it drops right into the 100mm wide BB of the increasingly popular fatbikes and off-road bicycle frames. There are several BB widths available with the BBSHD drive, so you are not restricted to just using it on a 100mm BB width.

Check out the falcon-ev triangle bag, and try to find a good lipo battery with bms which should fit easily in that bag. I have fit as much as 48v 20ah in one. Please read our story on geared hub motor 250 watts for the 2 hub motors i would recommend in this power configuration…either the Bafang or the Cute. https://www.electricbike.com/three-250-watt-hub-motors/ Also there are 2 other stories on this site focused on 250 watt motors written recently. Good luck.

Lastly, think about cargo. A loaded backpack shouldn’t be an issue, but if you want to carry child seats or pull a trailer, consider bumping up to the next higher power level to ensure you have the power you need when it counts. I personally like to err on the higher power ebike side. If you don’t use the batteries for electric bikes power all the time, that’s fine of course. But when you really need it, you’ll be happy that extra power is there.

Court- Excellent article (and I have read a lot). I wonder if you can weigh in on a system I am trying to build. I have a Montague Paratrooper (a bike that folds). I need to fold it and put it in a drift boat. It needs to weigh as little as possible and must have a removable battery and about a 10 mile range with an average speed 20+ mph. I had sort of “settled” on a Bafaang 750 or 1000 watt with Dolphin 52V battery (kit at Lunacycle). Now I am not so sure after reading the pro/con of your article. Cost is certainly an issue and ease of installation. I have been biking with out the motor, and I have numerous fairly steep (6-8%) hills. What do you think I should do? Rear hub, smaller battery. Thanks !

Hi Derek, most engines produce a bit of drag when power is not being exerted because the pistons are still rotating (unless you shift into neutral) and this is why large trucks downshift to “engine brake” down hills. Electric motors are different and don’t produce as much drag, instead, direct drive gearless motors possibly like the one you rode with create a bit of “cogging” which is the staters repelling the magnets inside and this resistance can be increased by actively generating and storing electricity like a little power generator using regenerative braking but most electric bikes don’t offer this. Some motorcycles and higher-end ebikes do but most light weight low speed electric bicycles opt instead for standard brakes… usually disc brakes that do offer enough power to stop but require the user to apply them actively (usually the brakes also cut power to the motor when pulled for safety). I hope this information helps to guide your use of the mobility scooters and I wish and your wife you safe riding! It’s difficult for me to be any more detailed with feedback as I do not know the exact vehicle you’ve got and may not have tried one similar.

So, I’ve been doing some research about eBikes (I started looking at them back when Lee Iacocca was pushing his eBike). I’ve recently become interested again and I’m looking for some advice about what kind of bike to look for.

And that’s the majority of the electric bicycle parts that I buy on a regular basis. As I think of more ebike parts that I’ve left out I will be sure to add them. I’ll also update as I find better prices in the future.

Hi Joseph! Sorry for the confusion… I realize it can be overwhelming when you really dig down. Two things come to mind for you regarding a good mid-drive system available after-market and the internal shifting question.

The BionX P350 Electric Bike Kit keeps the weight of your bike as low as possible and has a 350W motor and a 48V Li-ion battery. The fully automated pedal assist and throttle modes of BionX kits are intuitive and blend speed with power in a lightweight conversion package that weighs just 17 pounds. The BionX D500 Motor Kit comes with a 500W motor and a 48V Li-ion battery and is great for the rider who seeks for lots of power and torque. It boasts the most powerful BionX motor available in a package that is lighter and more powerful than previous BionX designs thanks to a wider diameter, lightweight casing and a design that put the magnets at a greater distance from the center of the motor than previous models. This makes climbing hills and getting up to speed a breeze! 

I’m buy a emotion bike 350 watt I’m going to ride it back and fourth to work going to work Is 7 blocks and 7 blocks back will it be fast enough or have the power I’m spending 3 grand I just want to know if I’m doing the right thing we don’t have many places to buy bike like this in Alaska so there hard to find

Choose a Hub Motor kit for mostly street riding or if you are looking to get as much speed as possible! Mid Drives are lighter in weight (save about 6-9 lbs), and are better for very steep terrain, such as single track off road since they are able to utilze the bikes native gearing in the back. 

Almost every person to whom we introduced our Smart Wheel idea liked it much more than buying a traditional E-bike. To achieve our mission of getting more people enjoy the fun and convenience of E-bikes while saving resources of the planet, our biggest stumbling block is spreading the word about our product.

The Semcon electric drive system looks to be easily swappable between bikes, as it is merely mounted to the seat tube, and not integrated into the frame or the wheels, with no external controls to install or remove. It’s a simple solution, and one that could make electric mobility a bit more accessible, assuming it will be developed and get to market for anywhere near the claimed $100 cost. There are some issues with friction-type drive motors, most notably the potential wear on the surface of the tire, as well as any drag from the drive unit on the wheel at lower speeds (when the motor isn’t running), not to mention the possible weak point of needing to get the device mounted at the optimum spot on the bike frame for maximum efficiency, and the question of whether the device will work as well on skinny tires as with fat tires.

Hi Lara! Sounds like a neat project… I hate to be the bearer of bad news but I’m not sure any standard electric bike drive system will work with the trike I saw in Google image search. I can’t be sure I’ve found the exact model you’re describing but the tiny front wheel is too small to be swiched out with a hub motor and so far up front that it would likely spin when activated (most body weight tends to be distributed through the rear wheels on trikes and the one I found was super long). The rear wheels might work with a hub motor swap but there appear to be axles fixed to the frame (not poking through on both sides like bicycles), a hub motor would require no axle on the bike, just a dropout like on the fork of a bicycle. You might have luck with a system like the RideKick that pushes you but I’m not sure if those are still for sale? Consider buying a purpose built electric trike vs. doing a conversion, it will tend to work much better and sometimes people post them for sale on Craigslist or in the forums here. Hope this helps!

Mounted on your bike’s front fork, the Electron Wheel is a breeze to install and takes most users around 30 seconds.

Alternatively, you could simply connect the discharge wires in parallel when you want to use them together, and then disconnect them for charging separately. If you go that way, just make sure you never plug them in parallel when they are at different states of charge. A good method would be to only parallel them when they are both full.

According to some quick research I did, a city block is about 100,000 square feet which means that you can fit 17 blocks per mile. Given your round trip distance of 14 blocks… that’s way less than one mile and in my experience the new EVO line of Easy Motion bikes (which have ~417 watt hour batteries) will get upwards of 15 miles per charge even after hundreds of uses and on uneven terrain. Of course, your weight and the hills and wind all have a factor but you should be very good for just a mile or two of use.

My questions are regarding Torque: How to know, or calculate torque power delivered? The manufacturers tend to give a higher torque on the specs than the real one, it seems. How to be sure I get what I am paying for? I would like my next build to be stronger, as my 500 w/ 20 A/ 36V gets quite warmed up when I pulling trailer with two kids in it. Living on the west side of Norway, the next hill is not far away! And 1000 w seems a little much to me, as max power allowed on the roads in Norway (EU-regulations) is as little as 250 w.

Regarding a 40AH battery, are we still talking 36V? That’s a big battery for a bike, but if it’s for a pedicab, you might even consider lead acid batteries. Generally I advise against them for ebikes, but since a pedicab is stable and the extra weight isn’t a deal breaker in a flat area, it’d be a cheap way to get a lot of battery. If you can afford it though, there are some big batteries on Aliexpress that could be good for you. Lithium is of course more expensive, but it will last longer too. Here’s a 36V 40AH and here’s a 36V 25AH for comparison, both LiFePO4 batteries so they should last well over 1000 cycles – years even if you’re doing a complete discharge every day at your business.

Hi Wesley, the Easy Motion electric bikes are some of my favorite. They use quality battery cells, have a good motor (that feels more powerful than comparable 350 watt designs) and their range of models offer good on or off-road capability. It would be easier to help you determine range if you could approximate mileage vs. blocks.

Duke Eco-Marathon Team using an Electric Bike Technologies hub motor for the 2014 Shell Eco-marathon. The E-BikeKit motor provides optimal space saving because it does not require a chain (this makes it great for converting road bicycles to electric bicycles, which is what it is designed to do) but we hope to determine if it provides us with a better overall vehicle efficiency than our outboard motor.

I hope you did not, because that wouldn’t be a good idea: you’d probably  waste a lot of gasoline in acceleration and your engine would not be happy at all! But that’s what happens constantly with most of the existing electric bikes in commerce. 

I need your input on a trike conversion. I’m disabled, and working on converting a trike I got on the cheap to electric powered. I’m unable to petal, and handcycles are sooo out of budget it isn’t funny. I have a Trailmail Joyrider Junior. (i’m rather short so it’s a good size for me. The way it’s designed I can do a chain drive, mid drive or a hub (since I’m really just working with the frame) Which would be better for a full assist situation? I do have some graded hills around me too. Which one would be best?
