In addition to the normal commercial e-bikes, there are lots of conversion systems available. "Bafang" is one of the leading manufacturers in this area - both for e-components and complete systems.
Note: The M625 drive systems with CAN protocol, this motor is only compatible with the BT F22.960.C/BT F23.480.C batteries. Bafang M225/M325/M625 drive systems can only be used on vehicles intended for off-road use and designed to travel on unpaved surfaces. Please make sure to comply with local laws and regulations.
This conversion kit contains the following components:
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 M625 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.
The conversion is very easy and can be done by anyone with a little manual skill. Briefly described(In our video, we have shown this in detail):
