Gear Sensor for BBS01 BBS02 BBSHD Electric Bike Sensor Shift Sensor for BBS Electric Bike Gear Sensor (Black 2 (Metal))

Sensor arrived much earlier than expected and appeared to be of good quality, but with no instructions. I found a video online, but it was more oriented to a more professional installer. This is my first ebike. Some tips. First, you have to cut the sleeve the shift cable runs through, but YOU DO NOT CUT THE SHIFT CABLE as it goes through the body of the sensor. What I wish I had done. First, you need something to cut a small crimped end off the shift cable, as well as to cut the housing the shift cable runs through. On my bike(a GT) this housing looks like a plastic tube, but it is really a steel coil with plastic over it. I’m not sure what a bike shop uses to cut these, but a cutoff wheel on a Dremal grinder works fine. Side cutters not so much. After cutting the crimped end off the shift cable at the derailleur, loosen the bolt attaching the cable to the derailleur, then use a permanent marker to mark the exact location of the place the bolt clamped the cable. The video I saw then showed how to remove the shift cable from the shift assembly at the handlebar. This was a mistake on my bike and it would have been much easier to simply slip the cable sleeve out of the shift assembly where it leaves at the handlebars and then pull the cable out of the sleeve from there. The video said to pull the cable clear out of the sleeve, but it is easier if you don’t. Just pull it out to the place you marked and then you don’t have to restart it in the sleeve. Next, Plug the sensor into the little plug on the motor or controller so you know where you you have to mount it. I put mine on the down tube. Measure the internal length of the sensor (the cable sleeve inserts in both ends and you only want to cut out the internal length of the sensor body). Cut the cable sleeve and then insert the cut ends into the sensor. Both the ends of the cable sleeve and the sensor it self must be firmly attached to the bike frame or you will need more hands than you have to complete the installation. I used a small piece of 3M trim tape to stick the sensor to the frame and then ran several nylon wire ties over the sensor and the ends of the cable sleeve. Until you do this every thing just comes apart when you try to insert the shift cable. Once everything is firmly positioned, reinsert the shift cable from the handlebar end. Mine slipped right into place. Reinstall the bolt that clamps the rear derailleur to the cable and crimp something over the cable end to prevent it from unraveling. As a final step, I suspended the rear of my bike from the ceiling in my garage and used the pedals to ensure proper operation of the derailleur. This took a very minor adjustment. Then did the same thing with the motor turned on at assist level one. System worked perfectly. Hope this helps someone avoid a couple of my mistakes. When the weather improved I was able to road test the sensor and it definitely improves shifting. I have a mid drive motor and had to use a brakelever to cut power a get a shift when climbing.

My cable is a smaller diameter I guess. Frankly I'm kind of thinking that this part isn't that necessary. Bike shifts well while riding and haven't really experienced a time when it would be a necessity so far.

Wish it had mounting instructions, but no problem as I was able to come up with a functional solution.

Works smooth while shifting.It can be installed either direction. (Print down)I ordered ferals and a cutter. Don’t use wire cutters, the cable is harder material and it nicked my dikes. I found a Dremel cutoff worked best and a finishing nail to open the inner sleeve.To use the old feral, cut the out plastic cable housing and slide it off. I see a drill bit in my fingers to clean out the plastic from inside the feral.Installed on BAFANG BBS02B kit on a mountain bike.

When I shift gears, I feel a noticeable slowing as the gear sensor momentarily shuts off the motor to allow the chain to move to the cog I'm shifting to. I'm sure the slowing is as noticeable as it is due to the weight of the bike (substantial with the added weight of the motor and battery) and its rolling resistance. The brief loss of momentum isn't a problem, but it is a little disconcerting. I'm used to being barely aware of the mechanical aspects of shifting, as long as everything is adjusted properly. I didn't try my ebike without the gear sensor, so I don't know how much it improves the smoothness of shifting. I trust that it works as intended, reducing chain wear by easing mid-shift chain loading.

The listing clearly states that the brand is "Bafang." NO IT ISN'T. Bafang's gear sensors are made in the Czech Republic. This one is marked "Made in China." So, it's a knock off. I really don't like it when a product is deliberately misadvertised. I can't give this product five stars.Fortunately, the sensor is more functional than it is honest. I have about 80 miles on it and I haven't noticed any missed shifts yet.

I purchased my first Bafang mid-drive without an electronic gear sensor. At almost 10% the price of the motor/controller package, I wanted to check out how everything worked before making the added investment. Shifting worked fine under normal low load conditions. Climbing or accelerating, or riding under PAS or cruise control modes, was a different story. Drive train stress was obvious in spite of different strategies used to shut off power. (Results would vary under 'throttle only' conditions, but I like PAS and cruise control.)It doesn't seem like Bafang's OEM gear sensor could be any better than this. Pinching pennies, you might like to consider this source rather paying for it in the motor package, but I would highly recommend a gear sensor for any multi-speed medium to high powered mid-drive system - especially if you find yourself frequently running over 350-500 watts.

Out of stock from Bafang, but this worked fine for my build/

Protege la cadena y el cambio de velocidad

シフトチェンジ時にモーター動作が切れるのでギア周りの高い負荷が減る。ブレーキセンサーでブレーキ使って手動で似たような操作はできますがシフトセンサー利用の方が段違いに楽になる。標準装備にしてほしい必須のアイテム。モーター側のセンサーコネクタ自体はBBSHDには標準で付いているので加工も不要で取り付けも手軽。海外発送の場合到着日数は10日配送保証しているaliexpressの方が速かったりしますが、個人輸入するのと大差無い価格ならサポートが優秀なAmazonでの購入はオススメできます。

Definately worth doing to save some wear on the drive train.

works well

Ne fonctionne pas toujours😆
