That was our first design. But it did not cool as much. But I’m not stopping anyone from coming up with it. It’s all about designing and testing.
But I do highly recommend putting urethane sleeve covers on the middle part where we put our urethane covers. That part of the motor gets snagged easily when going on uneven surfaces. If you leave it unprotected and only with metal showing, it can actually stop you and make you go flying forward. With a urethane cover, it acts like a hubmotor just spinning and rolling on and over the road hazard.
