Thanks, I didn't appreciate the variants of speed control. Any KT controllers/suppliers you would recommend?

Thanks, opened the controller up and it looks pretty water damaged so I think it's time for a new controller. Note that the controller changed both power and speed with different levels so wasn't pure speed control. So the question is, what controller do i replace a 36v 24a bafang controller with?

Thanks, would it be a DIY fix with a bit of soldering? Also just realised the 370w is way higher than level 1 was, I think it was about 230w before and 2 was 300 ish. So it seems to have defaulted to 10A regardless of setting.

Just realised I could lift the wheel off the ground and run it on the throttle with the brake on to limit speed. So didn't have to wait till tomorrow. I was getting 370w max (c10A) in any power level, so same power in all levels.

Thanks, will give it a try tomorrow, although hill climbing today I wasn't getting more power out of the higher assist levels. That's not how this has behaved until today, which is what's confused me. Normally increasing assist level increased both power and the cut off speed. I think it's actually a 20A controller so should be getting >700W at full power (which I was till today).

Hi, new here and need some help to diagnose a fault/identify a fix. I have strange behavior from my Bafang hub drive controller which means it wont give me any more power that level 1 assist. I can select different power settings (1-5) from the display, however regardless of power setting I get a maximum of about 10A (c.400w) output from the controller, which is equivalent to setting 1, but the speed setting at which power drops off increases at each level as it did before so the display is talking to the controller. It was working OK three days ago. Previously I would get a max of c.750W output from the controller in level 5 (rarely used). Any inspired ideas would help, or if my controller is done some suggestions for where I can get a like for like replacement.
