Thank you, this helped me disconnect the pas. 👌

Most sensors on electric bikes are in inside the bottom bracket

I need help my controller is super basic with waterproof connectors 4 wires total with xt60 and pas slightly exposed the other 2 are the jolet waterproof plugs I think the pas plug with the red blue and black wires is faulty I have done a image search on Google of my exact controller and there is not a single one like this and I haven't seen a video on RUclips for this particular style either I can't complain I put this bike through hell lots of rain lots of bad weather lots of exposure

my motor kicks when I pedal backward too, 12 magnets pas, I don't understand if the sensor should be flipped, rotated, or the ring is somewhat wrong?

My ebike is also now doing this

[@fastandyc]

You need to change in your settings so that it says run f not run b​@@LoLErMan13

Do you know how I could install 2 pas sensors on 1 ebike for 2 motors and 2 controllers ?

[@128bike]

Hello Anio
You just caught me at my computer so a fast reply. This would be very difficult to do but it is possible.
Two options:
1. Use one sensor and spilt the cable onto two plugs, one for each controller. Must make sure you get the cables wired correctly otherwise to wont work.
2. Put one sensor on the left side as intended. Second sensor you can put on the right side but you need to do two things. Make sure you have enough space between the chainwheel and the frame to fit the sensor or change the bottom bracket to longer one (also must think about the chain line) Then you must rewire the two cables that give signals for direction because when you change the sides of PAS sensor (left to right side of BB) the signals for the direction are then in reverse meaning that the engine will start when you pedal backwards.
So not an easy task but still possible just some careful rewiring has to be done :)

Can it measure speed

[@michaelnoardo3315]

im trying to configure my pas with my S866 controller and ESC brainpower 866 but my wheel has no Hall Sensor , i cannot make it work
does PAS work with Motors with no HallSensor ?

[@128bike]

Hi Michael
As I know you can't use PAS sensor on motors without Hall sensor.
I am not an export on this topic, more a mechanical guy. But I have some basic knowledge from personal experience :)
If you have a way double check just to be sure.
