 Electric bike   Basically, electric bicycles can be categorized into two broad categories, depending on the location engine. If engines are integrated into the wheel hub, often back centrally located motors are directly integrated into the frame construction in the crank gear.  engined bike hub motor located in the hub back place, this system is known as "direct drive" enjoys a propulsion unit stronger and faster, but does not produce very high torque. And adding considerable weight and high air resistance, their efficiency is much reduced compared to the potential that they have. One advantage is that you can recharge partially disengaged when and because they are almost completely silent sliding parts. There and back motor hubs that allow mounting a gear block and appear completely different from normal hubs. Higher torque offset lower speed, but a big minus is the lack of recharging option of walking and sliding parts contribute to significantly highe
