BAFANG E-Bike Shift Sensor Mid Drive Motor Gear Sensor 3Pin Shift Gear Sensor Cable Electric Bike Parts BBS01B BBS02B BBSHD;

The Gearsensor acts like a speed shifter so you are able to shift your bike at full throttle and barely fill the throttle cut off.

It will make your BBS02 or BBSHD shift faster, smoother and safer. 

The Gearsensor is plug and play with any BBS02 or BBSHD in place of one of your ebrakes and is a 15 minute install. 

If you install it with our newest edition of BBS02 or BBSHD the controller has a separate ebrake connector so you can use both ebrakes and the gear sensor. If you go with this setup the shifting power delay is much shorter than using the ebrake connector.

However the gear sensor will work with all bafang mid drives by simply connecting it to one of the ebrake cut off switches.
