1. Wouldn't it work even better to make the wheel into the motor? (i.e., put the permanent magnets on the wheel as close to the rim as possible, further from axis of rotation, for more torque.) This would be like those stereo LP record players where the turntable is the motor.
2. Or, with vented disc brakes, to insert the magnets into the slots between inner and outer disc surfaces.
3. Would a pulse width modulator work to control speed and torque? It's on/off timing would control the length of time that electricity goes to the stator windings--longer for acceleration and more briefly for cruise. Would such a pulse width modulator also serve as a cruise control device?
4. How hard to rig it for regenerative braking?
5. How heavy a battery would be needed?
