hey,
look at this:

put the motor and the electronics to the front; batteries into the center of the frame. you will need a big outrunner, at hobbyking they have som 8cm monsters with about 250 r/min.
you could design a mount, where the motor gets - by pulling a lever - contact to the tire. so when you don't want to use the motor, no problem when going downhill very fast.
they have now designed a e-velosolex:
anyways, cool idea, btw!!!!
just recently I saw a high-end e-bike on tv, fast like a motorbike.
