It's done. Peipei motor + tire (60v, 800w), Raptor original swingarms, Raptor drum brake just moved from original wheel to the new one. Screw holes and everything is identical, so it's simply a matter of swapping the flange for the Raptor's. I got the tire + motor yesterday, did everything tonight. Just came back from a 25 km test drive. Acceleration is perfect, no disturbances between the front and rear motors (front is still original, but not for long). Just left the hall wires of the new motor untouched.
