i wanted to make an electric bike but i dont know how to make the chain spin... how does it work?

does electricity and battery make it spin or what how does this all work?

Answer
You are right. An electric motor and battery are what is needed.

But most electric motors are either direct drive in the rear hub OR there is a roller that drives the front wheel directly. With your level of expertise I'd recommend getting a kit. Australia do some good ones.

Looking for a forum dealing with home built electric motors?

Does anyone know of an active place to discuss and learn more about electric motor design? Specificaly, pancake or hub motors commonly used on electric bikes and newer hybrid cars.

Answer
Start by googling Beakman motors
