Axle Electronic the key thing may be that this part is faulty, note that in this photo there are two different components that you have? with two processors or one
ll components were moved from the new engine, only the electronics was left over from the old one I made 19k km
So yes, the first motor damaged the bearing and the motor housing, everything else was good except for one thin washer that broke.
I put on a second engine that I bought a year...
I had the same, a new motor drove 300km, I bought a new battery holder but it didn't help, the pressure sensor is probably broken, I put all the electronics from my old motor and it works.
You could still wear a shimano ep8, or a bafang m500 or m600
