A previous reviewer said to buy more, as they are very fragile and you will probably break one or two. True. When mine broke on the road, my bike would only go backwards. A long walk home resulted, and I had visions of money sprouting wings and flying away. The simple fix is to swap out two of the three sensor wires. I did that, and rode on for over a year before I broke down and fixed it. Videos are on YouTube. I foud it an easy fix, but I am a retired pro mechanic. Still, cheaper to fix than to trash. Keep on cycling, and stay out of the wheel wells.

Llegó a tiempo y es justo lo que pedi

was getting an error code on my bicycle and wheel motor functioned intermittently/stumbled. I took the plate off the motor and found a fragile and broken lead on one of the hall effect sensors. I pulled all three and replaced them with this part and the electric bike now works fine.

I just can't understand these distributors that ship goods from China and don't bother to add directions or just some simple paper that just shows you what's up. It really seems irresponsible to me that somebody would just ship you a product, especially something that's electronic and not have some type of documentation. And I'm not looking for a huge owner's manual or data I'm just looking for simple wiring diagrams and some installation device. I mean would that really be that hard sheet. Just looking for a simple wiring diagram and maybe some recommendations on installations. I'm also trying to ascertain of how much effective loss you get when you don't use these hall effect sensors. So far I can tell you my 1,000 watt hub runs pretty decent without the sensors with a pretty good controller. I think that if you have a sign wave controller, you don't need all sensors and if you have a square wave or box wave controller or at least a less expensive controller, you can't run it without your Hall sensors The only major problem with all of this in general has to do with the fact that the sensors themselves need to fit in these little cavities that are part of The stator and there's not a lot of room. If the hall sensor would stick out even a fraction of an inch, it would create havoc inside your hub motor. Need to throwing out or poking out or cleaning out the cavities to get the whole sensors in place and then mount the PCB the little board but it's a real mess and I can tell you you may want to just consider going hall less. Also, upon research, all effect is not the only way to sense the position of a stator on a brushless DC motor. There are other ways and you can read about those ways online. However, the controllers for those alternative sensors tend to run quite pricey. However, if you don't mind laying the money out for a different style controller, you can do well without these whole sensors. While I'm on the subject, the leads that go to the sensor itself are quite fragile and spindly. I'm really wondering why these hub motors are not put together with more robust Hall sensor assemblies. I guess if they could save a few pennies they'll do it. However, it all sensors

EDIT: Contacted the seller. He said talk to Azon so I did Azon made it good. They sent me a new set at no cost. Happy..First off this is the only seller on Azon that sells these PCB boards so far, that's good..PCB was bad. Only had 1 good hall sensor that worked.. Yea I did that thing everyone does. I tore down my hub, then fixed then put back together.. Nope not working so I had to go and find my tester. Then dig it out. Then test. Yep the yellow hall was the only one working. So after a loud (****) I preceded to take the hub apart again. So this time I lined every thing up and got a magnet. Turned on the tester yep all good.. Got my 1000 watt hub motor up and running again..So I got 1 for the price of 2. Messaged the seller so will see.. EDIT..^..

Hall sensor worked to replace a damaged hall sensor on a bafang 750w wheel. Soldering required.

Switches worked well and motor has a smooth start as well as performance
