The specification of the new BBSHD includes a 12 fet Controller (30A), with a choice of Bottom Bracket Widths available.
Only the C961 currently Available
The Bafang BBSHD Mid-Drive kit includes the following. The standard controller settings are 30A, but it can be detuned in software to lower values:
- Motor with integrated controller.
- The bare BBSHD motor weighs 5.9kg (not including chain wheel, display, cables etc.). Shipped weight is ~8.3kg including standard Chain wheel.

- The kit can only be used on a 48V battery or 52vb battery. It absolutely cannot be used with a 36V battery (41V LVC), or any battery with a charge voltage of 60V or more. There are options for either either 13S Li Ion 47/48V batteries, or 14S Li Ion 50V Batteries.
We are able to adjust the controller software. Kits will be shipped with throttle configured for full power in all assist levels. There are also many user adjustable settings available in the display. The BBSHD is a more powerful version of the BBS02, it has a larger motor structure, which can deliver higher power levels than the smaller BBS02 and a larger 12 fet controller. See below links to view documentation on the kit and display.
The standard settings are as follows:
- 30A or 25A according to the chosen option.
- LVC (low voltage cut) 41V or 43V.
- number of assist levels are adjustable by the display.
- wheel size can be adjusted from the display.
