Bafang BBSHD BBS02 Motor Stabilizer Bar
The Bafang BBSHD BBS02 Motor Stabilizer Bar is very important if you are installing a Bafang 1000 watt motor on any bike. The Bafang BBSHD has so much torque it will eventually come loose and begin to move in the bottom bracket. All Bafang kits come with a fixing plate and a M33 locking nut. It does not matter how tight you lock down the fixing plate the motor will still come loose. This motor stabilizing bar holds the BBSHD in place in such a manner it cannot come loose.
If you are building with the Bafang BBS02 750 watt electric bike motor kit on a bike with a steel frame you will need this Motor Stabilizer Bar. The steel on many bike frames is harder than the fixing plate that comes with the Bafang kit and it cannot bite into the bottom bracket sufficiently enough to hold the motor in place. Please note that some bending may be required to get a perfect fit.
We use this product on as many bikes as is possible. It just makes for a better build when the motor is being held in place without the fixing plate. The fixing plate is literally crushed into the bottom bracket shell and that is what holds the Bafang mid drive in place. This products eliminates that need of the fixing plate altogether.
California e-Bike makes this product and it comes in two types. This is the one that attaches to the downtube. The other attaches to the seat tube or the chainstay.
We also carry the stabilizer bar flat model that attaches on the chainstay or the seat tube.
