In an effort to not change too much, say for the sake or argument that electric motor(s) would work to drive the two front wheels/tires (as opposed to the rear). How beefy of a motor would be required for each wheel? Does it really change the motor power requirement for the motor to be in-hub verses not? Would the most likely motors have magnets or be fully induced magnetically run? I have heard of breaking generators which generate some electrical power as a factor of breaking. I have not heard much of this in a while. Has this tech been proven viable? Any consideration of using supercaps in conjunction with the batteries? If I recall, they are more efficient by a significant margin. Just soooo many questions...
