## Description

Gear Sensor for BBS01 BBS02 BBSHD Electric Bike Sensor Shift Sensor for BBS Electric Bicycle Speed Sensor

Review: Works as advertised, everyone should probably get one of these for their BBS mid drive - I installed this on a new bike I was converting with a BBS02. The bike is for my wife, and I didn't want her to have to worry about the drivetrain binding/stressing during shifting. This device works perfectly and cuts the motor instantly when you move the gear lever. It seems to stay cut out for exactly the right amount of time, and it's hardly noticeable. I won't say the installation was super easy. You have to remove the sheathing from the cable, cut it, run the cable through the sensor, and then the tricky part is getting the sheathing back on. The cable wants to unwind, and if a rogue strand doesn't find it's way back in to the sheathing, it is kind of a nightmare. After some persistence and a couple of stab injuries to my fingers, I managed to get it in. Maybe you'll be lucky and get it on the first try. Anyway, besides that, the sensor was really easy to mount to the bike, and the plug fit perfectly into one of the reserved sockets on the BBS02. I'm really happy with my decision to get this for my build.
Review: Easy to install, plugs right in, really smooths out shifting - Purchased this sensor as part of an upgrade of a 2014 Bafang mid-drive system. The original BBS02 motor had started to skip and stick, so it was replaced with a new BBS02B drive unit. The new BBS02B has an input for this shift sensor, so I added it to the system. The sensor installs in the cable housing of the rear shift cable and momentarily shuts off power to the motor when sensing movement of the shift cable (either up or down). The attached cable plugs directly into the matching connector on the BBS02B. It works as advertised and smooths out shifting gears, reducing wear on the drive train. Not sure how well it will hold up over the long term, but for now it gets 5 stars for ease of install and function.

### ⭐⭐⭐⭐⭐ Just what we needed for our BBS02 BAFANG mid drive motor conversion
*by P***S on September 21, 2023*

We converted two bike to electric using BAFANG mid drive motors. This sensor works great and gives a smooth transition. This is the 2nd one of these we purchased. We have been very happy with the BAFANG set up and with the results. We're both in our 70's and we love riding again!
