I am sure this is a bit of a newbie question, but I was wondering what kind of drive system would be used with a mountain bike with a rear suspension.
Friction drive has no resistance while pedaling, which would be good for me since I want to pedal only a lot of the time, but it seems like the engine would be a lot weight bouncing up and down with the wheel. Also the forward mount could be a problem.
It would think a chain drive to a engine mounted in the frame (over the pedals) would have trouble with the chain changing slack as the wheel went up and down, since the front sprocket would not be on the same axis as the suspension arm.
