Bafang Shift Sensor For BBSHD BBS02
This is the Bafang shift sensor. We sell more shift sensors than any other small part. There is a very good reason for that. It does not matter what bike you are building the shift sensor make it shift smoother and will protect and preserve the entire drive train. The shift sensor shuts the motor off at the same time you shift gears. That relieves the pressure off of the drive train. Remember, there is a lot we can get away with riding a bike under our own power when it comes to shifting. When you add the power of a Bafang BBSHD or a BBS02 every shifting error will be magnified a hundredfold. These motors can snap chains under poor shifting. We use the shift sensor on all of our bikes. They are not expensive and easy to install.
