I have been wondering this question ever since I got my electric scooter (Volta 401) and I plan to upgrade it’s motor to 3000w from the original 1500w version. And since the wheel had the same configuration on the front and back I don’t see the reason to put another motor in the back and put the old one in the front. I put my ideas based on dual motor configuration for e bike where each motor have it’s own controller and connected on 1 throttle. Is there a reason why this might not work?
The speeds of each wheel need to be controlled precisely. So two separate controllers or motors might not work well if you just hook up two different motors.
