If your bike has no rear rack to install the taillight, you can install the taillight on the seatpost tube, and we will provide you with the mounting bracket. 

The rear light is AC 6V input and you can connect to your Bafang mid motor directly, such as BBS, Max drive M400, M420,M300, Ultra M620 motor which has 6V light leads. If your motor is M620, MM420, M400 or M300, please make sure you have the motor light cable for connecting the front light or tail light.  The connector for the BBS01/BBS02, M620, M400, M420, M300 light is called 4.8 pins; for BBSHD light leads, there are two versions, at the beginning, BBSHD uses 2 pins SM connector for lights, later Bafang change to 4.8mm pins for BBSHD lights(they are going to use the same connector for all the Bafang motor lights), therefore, please double check your BBSHD light leads before ordering the light for your BBSHD motor.

If you prefer to power the rear light by the battery directly, we also have another tail light which can be used with DC6V to 60V batteries.

If you are going to use the rear light for Bafang Max drive or Ultra M620 mid motor, this rear light will also be suitable for them.

If your original bafang BBS motor has only a pair of light cables, while you want to connect both front light and taillight for your bike, then you can choose a Y cable for the light.

Bafang provides two types pinion gears to us; we identify them by shaft diamter of the iron gear. The old version(BBS01/BBS02) is 10mm diameter for shaft and the new version(BBS01B/BBS02B) is 12mm diameter. Please check carefully when ordering the BBS spare parts.   Bafang no longer stock the 10mm pinion gear and we now only have the 12mm pinion gear available, please be noted. Bafang BBSHD iron pinion gear is also available now. We will provide grease with the pinion gear freely, It would be better to add some grease when replacing the new pinion gear.
