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?
Torque steer on a bicycle does NOT sound fun
You need front wheel drive with both a left and a right front tire contact patch to induce torque steer.
A contraption having these traits would be called a “tricycle”.
(could be called a “tadpole”, except tadpoles have a single rear drive wheel)
You also need unequal length driveshafts to induce torque steer. The absence of any driveshafts will lead to the absence of torque steer.
