Bafang Motor Cut Off Button


This small green button is used in place of the shift sensor for bikes with hydraulic brakes. In addition it is an important safety feature for all bikes as it instantly shuts off power to the motor in case of an emergency.We use this product on all of our custom bikes that have hydraulic brakes.


This is the  Bafang motor cut off button, also known as the “Green Button.”  A bike that comes with hydraulic brakes has few options when it comes to motor cutoff in order to shift without straining the chain. The Bafang motor cut off button can be used to cut power to the motor while shifting. Any bike with an electric bike motor kit needs a green button.

The Bafang BBS02 750 watt and the Bafang BBSHD 1000 watt electric bike motor kits are powerful motors and when that power is engaged and shifting occurs it can snap a chain under certain conditions. A rider has three choices: The rider can install hydraulic brakes with a motor cutoff switch preinstalled. A rider may use hydraulic brakes with adaptors attached to the external housing of the brakes. Or, you may time your shifts to coordinate when you stop pedaling. Or, a cyclist may use the Bafang motor cut off button. Prior to shifting, press the green button then shift, release the button. The Bafang motor cut off button is well worth the money and that is why we include it on all our builds.

Using the Bafang motor cut off button as a safety item is always a good idea. All eBikes need some way to shut the motor off in case of an emergency. For example, the bike falls over and engages the throttle by depressing the lever. How would you stop the runaway motor? Push the green button and the motor stops. This product works with the Bafang BBS02 and the Bafang BBSHD electric bike motor kit.
