Hello.

Thank you for your reply

before I tried to replace it, the original controller worked perfectly. The problem occurred when I put it back after trying the replacement.

I never disassembled the PAS sensor itself or touched the wiring. I simply plugged and unplugged the PAS sensor from each controller.

But what I did was connect the original controller with the display of the replacement controller. I'm afraid this may have disrupted the programming of my original controller, causing it to react in the wrong way to information from the PAS sensor.

Most likely, the problem is neither electronic nor mechanical. It seems to be the controller configuration that's at fault.

Is there any way to restore my original controller to its original configuration?

Thank you for your attention.

Hello. I have a problem with my rad runner plus ebike. The assistance only works if I backpedal (which is not particularly practical....). When I pedal forward, it doesn't activate.

However, it still works correctly with the trottle handle and the walking assistance (when you hold the downward switch).

I tried installing a new controller and screen, but they didn't work, and the problem appeared when I reconnected the originals.

I didn't touch the pedal sensor, except to connect and disconnect it from the controllers. So the problem seems to be in the software. Does anyone know how to reset the default settings on my original Rad controller, or does anyone have another idea for solving my problem?

Please excuse my English. Thank you for your help.
