Bafang Gear Sensor Installation

- Video showing how to install the Gear Sensor on Bafang Mid Drive Motors. The Gear Sensor momentarily cuts motor power when shifting. It mounts inline with the shifter cable and detects the cable movement. It sends a signal to the controller to cut motor power while shifting gears.
This video is very well done, as are all of your installation vids. In this video you mention two options for installation, but you only show the rear installation. I would love to see how it is installed near the front shift mechanism. I just ordered a BBS02 kit from you. I'm looking forward to installing it!
Same idea but different part of the exposed cable I'd wager.
Not only was this a helpful video it was totally chill, soothing and relaxing. FYI in my instance I didnt even have a cable covering so I was able to just install it without cutting anything. Zip tied it up nicely and hopefully it works! Thanks!
Do you have to undo it at the top .or just pull the outer casing out. Also do you have to undo the chain
I see lot of videos of this install and I've seen where the sensor wire is installed in both directions. My question is does it matter which way the sensor is placed or does it have to be placed a certain way.
I think it doesnt matter. as it's goal is to cut power when a change is detected
You are not the only video that yada-yadas over this, but could you show where the connector to the motor is?
I dont have any of these caps or "ferrules". Are they necessary for a proper install?
Question: the cable from the motor with the yellow plug. Usually is for the speed the speed sensor, are you able to run a speed sensor and shift sensor off the one rear yellow plug?
Bafang kits com with a speed sensor. Can that act as a substitute for a gear shift sensor or do you need to install both ?
How does this happen when the cable housing is internally routed?
Hi! Is it possible to adjust the engine shutdown time from the controller? I am thinking of installing a 750W bafang with the LINKGLIDE system from DEORE, but apparently changing gears is slightly longer. It probably doesn't matter, but I have a slight concern.
Excellent tutorial. thank you.
Break and shift sensors are optional? I have mechanical brakes and shift sensor is extra install?
Yes they are optional, however the motor won't stop when braking or shifting gears. You'll have to stop pedaling to stop the motor. I suggest reprogramming the motor to istantly cut power when you stop pedaling.
Hello!
Do you know in which cases you need the second cable with two ends that plugs on the end of the sensor?
Anyone know if this works properly with hub gears like the Shimano Nexus 8?
Very well, my good man! Thank you!
I’m having a hard hard time getting the cable to push through. Would a small amount of some sort of lubricant help? Would it alter the performance of the sensor if I put a small dab of grease on the cable to get it to slide through? Also, there are two screws on the sensor … is it possible to temporarily open up the sensor, feed the cable through and then close the sensor housing?
This should have been the default way to do it though: open housing of sensor and place on top of wire then close it back. we
would only have to strip a small part of the wire ...but i'll admit we risk cutting the wire inside doing that
"Use appropriate cable cutting tool". Folks, you can get a serviceable cable cutter online for the same price as a decent diagonal cutter. Use a cable cutter for cables and housing, please.
Yea thought that was funny myself. This guy must not work on bikes a lot :)

step 10 a coffee great video
Can I use the gear sensor socket to cut power to second motor instead?
Is the gear sensor compatible with the befang bbs02 please?
Yes it is
Hi, Do we need to have a Y-splitter as well or only the grear Shifter? And Does it work with 1000W (BBSHD) motor?
Thanks
You only need the splitter if you version of BBSHD doesn't have a dedicated gear sensor cable.
All newer ones of BBSHD and BBS02 have the dedicated cable coming out of the motor/controller.
@@MicroRCFiend Do you know if Bafang M400 250w mid drive have gear sensor option/wire?
@@ViljamiDrumming I'm not sure. I can't see clearly enough online pictures and also can't find the manual. Do have the motor or manual?
I'd expect it to have this function since it has to be used in various bikes with various setups. I'm also under the impression it's only older non torque sensing setups that didn't have the function.
I still don't actually know if it has the same higo connector for it though.
Why do you install it with the connection cable backwards? Is this a must?
No.
I was installed it in front.
Hallo! Entschuldigen Sie bitte, ich verstehe nicht so gut Englisch, könnten Sie mir bitte erklären, wofür Gear Sensor? Welche Funktion macht er?
The Gear Sensor momentarily cuts motor power when shifting. It mounts inline with the shifter cable and detects the cable movement. It sends a signal to the controller to cut motor power while shifting gears.
bei dem Gangschalten sollte die Kraftübertragung unterbrochen werden. Es könnte sonst die Kette, die Kettenräder oder der Kettenwerfer ruiniert werden. Fallst Du beim Schalten zum pedalen aufhörst stoppt der Motor auch und Du brauchst das Ding nicht. Aber niemals vergessen! VLG aus Kalifornien
no link for where to buy?
Can you install the gear sensor either way, with the sensor wire facing rear of forward?
I'd like to know this also
FOrgot to put the nub back on. The next person who works on this bike will have a fun time....
Hi,
I'd like to know if I need to buy an extra T cable for my motor (bbshd) or just plug it in?
If your motor is the older one, you need the 2-1 wire, if your motor is the newer one, it would have a dedicated wire like in this vid.
@@kaikart123 mine is the bbshd, but its new. By the new you mean the M625?
@@luist76 no, there are older BBS that do not have dedicated shift sensor connector and you need the tee wire to tee from one of the brake wire.
@@kaikart123 how can I tell if i need it or not? My motor has a 3 pin yellow female plug, a 3 pin black female plug, a 8 pin female plug (all round shape), a 2 pin female plug (square) and the battery plug. Also have a T cable with male 8 pin on one side and 2 female yellow, one male yellow (all 3 pin) and a green 5 pin male plug. All of these are accounted, 2 yellow for brakes, green to display, yellow to accelerator and 2 pin to front light. I can't see how to connect the shift sensor...
@@luist76 you don't need the tee
please reply as I'm planning to get one real quick.. is this a must needed for the bafang mid drive?
No its not needed
In my opinion yes.. Or shift like a Grandma
This bike was really easy to assemble ua-cam.com/users/postUgkxMesz3KOGEmwmvyKQfLfrRSUXLFzfVHZA and required very few adjustments out of the box. The wheels did not require any truing/adjustments. The frame had some small scratches, but nothing major.I did replace the seat though - the seat it came with was very uncomfortable. The tires need to be re-inflated every 4-5 days, but this appears to be quite common for the narrow 700x25 tires.Overall, in my opinion, this bike looks and rides like a much more expensive bike.
How is it different if installing up at the shift mechanism?
Maggie and David Cogswell It is no different. It's just a little wheel that detects the movement of the cable and triggers a sensor. That cuts the power. I don't bother with them. They are pretty crap really. You can use a brake cutoff to do the same job much better.
Going to be installing one of these on a Terra Trike Rover I-8. Was wondering the same thing. Do we have to split the sheath on the shifter cable closer to the shifter to install this thing? And with the I-8 you stop pedaling to shift gears. Wonder if I will even need it? Can't see where I would unless I was running non pedal assist and only using the battery.
Bowden cables and housing should be cut with Bowden cable cutters, not wire cutters
you installed it backwards...
Custom built bikes great bunch sent me here , I think what I’m trying to say is anybody can do this , HELP 🥳🥳🤡🤡🥴it ain’t that ard
