I have a skyhwak frame with Skyhawk motor. I don't like it that the drive chain for the motor does not freewheel when I pedal, which I like to do a lot. I would like to get rid of the drag. I've seen the one kit where you have to take pins in and out too much work. I'm thinking of using a freewheel shifter kit which would alow me to use my derailer gears .the question I have is does the chain drive part of the shifter kit also freewheel or will I have the same problem with the drag from the motor chains?
