Which motor is best for electric bike?

Rear motors are best for riders wanting or needing more power, or those looking to incorporate a throttle. There are also some new electric road bikes with small 250W rear hub motors that can be very stealthy with an integrated battery for a clean, traditional appearance.

Are e bike motors AC or DC?

How much power does an ebike need?

Just pedaling along at a typical cruising speed for a non-sporting rider (about 9 mph) takes about 30 watts, about the same energy as normal walking. Go up to 20 mph, and thus rapidly increasing aerodynamic loads, and 220 watts is needed—more than most non-athletes can sustain.
