Gearsensor for Bafang Mid Drives

Gearing System Options *

Current stock: 0
  • Intelligent sensor that will power down or shut off the motor during shifting to avoid chain grinding and cassette breaking 
  • Extend the life of your gears indefinitely with the gearsensor
  • An absolute must for mid-drives
  • Made for both deraillers and internally geared hubs


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. 

Here is a link to the manual and installation guide on the Gear Sensor

Luna Cycle is proud to be one of 2 distributors of the Gearsensor in the United States.

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 ones with the luna cycle logo engraved on the side) 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.

Support notes: 

Please see this documentation to protect your gearsensor from mud and debris for long-term reliable use.

See this documentation to service your gearsensor in the event an unprotected gearsensor gets clogged up with mud.

Very good

I was not sure at first but it makes a huge difference. My next step is to buy a controller with the gear sensor plug as I have mine connected to the brake connector and the delay is a bit too long.

Essential for middrive

Thought I wouldn't need this (optional but recommended) accessory. I probably wouldn't if I rode mostly on the road, but for off-road - essential
