The Bafang Ultra M620 is the ultimate motor for your heavy-duty eBike with incredible robustness, reliability, and power. We have upped the performance specifications to 230Nm and a maximum power output of 2500W — this motor can handle the heaviest loads on the steepest inclines. This is over 60% increase from stock!

With all-metal gearing, an integrated torque sensor, the ability to use a throttle, and a big, robust motor core, this is the equivalent of a diesel engine in the e-bike world.

This is the CANBUS version of the motor. The UART version can be found here.

Available in 48V or 52V versions — you must let us know what firmware you want us to flash prior to shipment. This will fit other brands as an upgraded motor such as Bakcou, QuietKat, Frey, Nireeka, etc., but you will have to know which version you have, UART or CAN. The easiest way to tell is to look at your display connector: a round connector is UART, a triangular connector means CANBUS.

This is a bare motor. Accessories like wiring harness, speed sensor, display, crank arms, etc. are NOT included and must be purchased separately. This is a very powerful motor system and requires a battery capable of discharging 50A.
