Yes, it is a bit heavy but for my purposes it is okay. But you do raise a good point and one additional benefit of staying smaller was to minimize additional weight.
Thanks for the links! Great stuff.SlowCo wrote: ↑Mar 27, 2018 5:57 pmThere are ways to cool hub motors:

Because the steel scooter rim is welded onto the hub. The car hub motor has 4 bolt on the outer plate to mount a rim over the hub. If you can find a 10" steel ATV rim that can go over the car hub motor you can use that. I wouldn't try to weld that rim onto the hub as the heat could demagnetize the magnets inside. Instead remove the inner steel ring of the rim and (have someone) make a steel ring with the hole pattern of the 4 hub motor bolts and an outer diameter that matches the rim. Weld it as far to the outside of the rim as possible so the rim can go over the hub as much as possible. Maybe relocate the air nipple hole if needed. To stiffen up the rim fill the room between the rim and the hub on the axle side with pieces of rod.jaybee9 wrote: ↑Mar 27, 2018 6:34 pmHmm... They have the same motor mated to a 10 inch scooter rim:

Why is 10 inch okay for scooter but recommend 12 inch for car?
I was planning to put the motor inside the rim as shown below. Obviously, the fit would be tighter radially as they are probably showing a 12 inch rim.
