This review is for the gear shifting sensor that triggers the motor to momentarily shut down while you're shifting gears, so your chain and gears don't get damaged or worn excessively by hard, jarring shifts.This is a much-needed addition to the Bafang mid-drive e-bike conversion kit. Without it, every time you shift your rear derailleur the chain will slam into gear under power, shortening the life of both your chain and cogs. You could simulate this by slightly pressing on your brake while shifting (assuming your brakes have sensors on them), but it's nice to not have to think about it.This didn't fit my bike the way it shows in the video I saw. In the video, they show this being installed on a bike with cable casings. A section is cut out of the casing and this is installed where that used to be, with the remaining casing butting up to the sensor on both sides with a seal between the sensor and the casing. Although my bike has some casings, on most of the chain stay it is bare cable, and that is the only place where it was practical to install this.To get around the problem, I cut a length of old casing and installed it on both sides of this sensor, then zip tied the sensor and the casings to the chain stay. Without doing that, there is no way to keep water out because there is nothing to hold a seal in that would normally go between the casing and the sensor.But after getting around that problem and getting this installed, the bike shifts smoothly and without jarring the chain and gears.
This sensor works great. Although the shift sensor is considered optional, it really isn't if you don't want your drive train destroyed by over-torque'd shifts. This sensor takes the motor load off for about .5 seconds when you shift so cog changes can occur smoothly without banging up your cassette and chain. Works great and really should be supplied with every conversion kit. Installation is straight forward but be prepared to swap out your shift cable at the same time.....my original cable was too short after adding the sensor because I needed some additional sweep to the derailleur.
