The Cute 100 rear delivers as much power to the road as my Bafang SWXH rear.
I ordered the Cute 100 with the 201 rpm option for more torque for a 26" wheel - more winds.
The kit came with all sorts of junk I didn't use.http://www.bmsbattery.com/ebike-kits/426-250w350w-q-85100sx-motor-e-bike-kit.html
The Bafang is perhaps a bit better on a hill but the Cute 100 seems to go a bit faster. More on this later. I should really start a new thread for this but here it is for now.
Rocky Mountain Element Race 1999 19" Frame
2 x 6S Zippy 4000 mAH Lipo Batteries from HobbyKing
Methods LVC cell monitor battery protection boards with breaker board power cutoff.
BMSBattery Cute 100 Rear Kit includes:
Cute 100 Rear 201 rpm for 135mm drop out
KU63 15A Sensorless or Hall Sensor Controller. Good to about 15S/63V I think.
Waterproof Connector for Hall and Motor Phase wires - too cool.
I've run the Controller at 14S okay and BMS said it was okay. Haven't tried 15S/63V yet
but I suspect the limit is the 63V capacitors in the controller.
