Functional principle and advantages of Bafang M225 mid-drive motors

Compared to the hub motor, the mid-drive motor doesn´t transmit the power directly to the wheel, but the bicycle chain. This means, your rear bicycle gears can also be used with a motor assist, which is not only an advantage when riding uphill. Further advantages are ideal weight distribution, low center of gravity, and a very natural riding experience. Furthermore, the front and rear wheels can still be changed without any problems.

Bafang M225 motor function is very simple: The electric motor powers the front chainring with an internal gear ratio of 22:1. An integrated clutch makes it possible, that the crank arms won´t be moved while the chainring rotates forward.

Bafang M225/M325/M625 advantages:

The Motor is very silent.
Pedaling resistance is very low, even without system operation
Bafang M225/M325/M625 motors are very low maintenance
Spare parts available and easy to change for yourself
Magnesium alloy shell, better heat dissipation
