Bafang BBS02B BBS01B Controller

This controller is for the Bafang BBS02 750 watt motor. It is not for the Bafang BBSHD 1000 watt electric bike motor kit

This a replacement controller intended for the 48V 750W Bafang BBS02, it can be used with either the 350W or 500W or 750W version. The controller includes a section of the motor housing and all connections. It may be necessary to change the battery supply connections, it does not come with the molded waterproof supply connection. The connections, housing etc do add quite a bit of cost, so it is relatively expensive. The sealed PCB makes them rather difficult to do a DIY repair, so it is much more practical to simply swap the controller section. Installing the Bafang BBS02B or BBS01B controller can be done by anyone who has the patience required for the job.

It might be added that there are many instruction videos on the web to assist with this task. This is one of the reason why the Bafang is such a great choice. About the only thing that can go out on these motors is the controller. When it does go out it is a simple and inexpensive fix.
