Batteries aren't exactly featherweight, and that results in rather heavy electric bikes that are in the market. The BionX conversion system helps solve that dilemma, as it can be fitted onto any bike and has a maximum weight of 15 pounds. This is made possible by replacing the rear hub with a seven pound, 350 watt gearless and brushless motor while the battery pack is fastened to the frame.

Perfect for those who love tackling hills, since going up consumes a whole lot of power while down hill is a great way to charge itself.
