Mini Hub Motor Mountain E-bikes

August, 2012

Electric bike home builder Nader Alizadeh lives in Hamburg Germany, where electric bikes are popular, but restricted to a maximum watt limit of 250 watts. Unlike most home builders these days who focus on speed, range and affordability, Nader decided to focus on stealth and minimal weight, so that his E-bikes look and ride like bikes. Climbing hills is not an important consideration for him because where he lives is not very hilly.

To achieve his goals Nader uses small geared 250 watt hub motors which are light weight and small. He uses one of three manufacturers, either Tongxin,  Bafang or Cute but he prefers Tongxin because he finds them to be the quietest of the 3, and he has a local E-bike dealer who stocks them, so they are easily available (read our article on these 3 mini hubs ). He uses 250 watt hub motors  in multiple configurations: front wheel drives, rear wheel drives, all wheel drives (motors in both wheels)  and recently even began crafting the ultimate hub motor application .mid drives. (read our article on mid drives ).

How is it that one  home builder is able to make multiple  electric bikes out of his garage that look better and perform better than 90% of the commercially available e-bikes in the USA for a cheaper cost?

Well for one he is making some pretty big compromises, settling for relatively small (180 watt hour) battery packs and small 250 watt hub  motors. (read our story that asks: Is 250 watts enough ?) Since his components are so small they are easy to hide. Check out the $3500 Faraday electric bike for a commercial comparison.  Also he is starting with decent  and affordable platforms which are commercially available mountain bikes.

Although not speed machines, the benefits of Nader s super clean looking and light weight electric bikes are obvious to a bicycle purist. Looking at his bikes, you can barely tell that they are electric powered.

Notice a few key features of Nader s Bikes:

All of his bikes are based on mid to high end  mountain bikes.

Most all of his bikes run on 36 volts, and stay close to the legal limit of 250 watts.

Most of his bikes utilize custom built 36V / 5-Ah 180-WH water bottle battery packs which is adequate for most of his rides

When he needs extra watt hours he carries extra battery bottles

None of his bikes weigh over 45 pounds even when using 2 motors.

Most of the controllers are built into the rear seat bags.

Most of the bikes are equipped with quality Schwalbe tires.

Nader is a collector at heart, and once he found the right combination of controller, motor and battery he repeated that winning combination, resulting in a garage full of very beautiful, yet similar E-bikes.

Lets do a photo tour of Nader s stable of beautiful electric bikes:

This Bergamont bike has a Tongxin 250W hub motor in the rear. Notice how well the motor hides behind the rear disk and cassette.  Controller is in bag and battery is in water bottle.
