The gear sensor is a great way to get smoother shifting with your mid-motored electric bike. A common issue that folks run into is that when they shift their bike's gears when the motor is on power, the gears make a not-so-smooth transition - leading to loud bangs when the shift happens. This gear sensor recognizes a gear shift by monitoring shifter cable movement and temporarily cuts power - this leads to smoother shifts.
This gear lets your bike's derailleur cable run through it.
Note that BBSHD motors already have a connection spot for a Gear Sensor right on the motor. BBS02 DOES NOT have this extra Higo connection.
Options for adding Gear Sensor to BBS02:
1. Plug it into one of the brakes (this would mean that only one of your brakes had engine cut off)
2. Use our y-splitter to get cut off on both brakes and a Gear Sensor.
Note that this gear sensor only works on bikes with a derailleur. Does not work with IGH.
