I bought a MXUS XF08 rear geared hubmotor off ebay. Cheap at $93. Maybe too cheap.
https://www.ebay.com/itm/MXUS-Ebike-Hub-Motor-Wheel-XF07-XF08-250W-Brushless-Gear-DC-36V-Electric-Bike-/163913340500
Put it in my 20" bike, using a 20A KT sinewave controller and LCD3. The motor only pulled 250-280W on 36V and around 400W on 48V. My BMS Battery Q100H would draw 500 and 800 watts respectively on the same batteries. I set P1=88 for the Mxus and P1=210 for the Q100. I haven't found P1 to do anything but provide the right speed display, but maybe I'm wrong and it's it's a bottle neck here.
Anyway, that's a bummer. I had planned to stick in my 9FET 25A kT-controller if the MXUS was any good.
Any comments appreciated. I put the Q100H back in the bike.
