Golden Motor Magic Pie 5 1000W Fat Bike Hub Motor Kit (26" x 4")

The FATBIKE Magic Pie 5 1000W hub motor kit brings Golden Motor's all-in-one Magic Pie 5 to fat tire bikes. It comes laced into a 26" x 4" wide fat bike rim, with the Vector sinewave controller built inside the motor. You get strong, quiet power for sand, snow and trails, with regenerative braking and Bluetooth programming.

For off-road use only. At 1000W, this kit exceeds the 750W limit most US states set for e-bikes, so it is intended for off-road trails and private land.

Designed and supported by Golden Motor, with a 1-year warranty handled directly by our team.

FAQ

Hub motor or mid-drive for a fat bike?
A hub motor is simpler and puts no extra load on your chain. A mid-drive like the Bafang BBSHD climbs better on very steep ground.
