A common issue that folks run into is that when they shift when the motor is on power, the gears make a not-so-smooth transition - leading to loud bangs when the shift happens. Thi s gear sensor recognizes a gear shift by monitoring shifter cable movement and temporarily cuts power, leading to smoother shifts. This gear lets your bike's derailleur cable run through it. * Note 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: Plug it into one of the brakes (this would mean that only one of your brakes had engine cut off). Use our y-splitter to get cut off on both brakes and a gear sensor. * Note this gear sensor only works on bikes with a derailleur. Does not work with IGH. Show more
