My bike is a Commencal Meta 55 with a GNG 450w Brushless Mid Drive connected to a 9FET 3077 Mark II (Sensored) LYEN Edition Controller. I have just installed a PAS Sensor to the crank and the response is not what I expected. There is no continuous power as I pedal. I am only getting a very low power and brief motor response with each revolution of the pedals causing a slow forward jerking motion. I have the sensor less than 1mm from the magnet ring. I have spliced the PAS wiring into the throttle cable and have double checked my wiring colours and connections.
Can someone please advise where I am going wrong or is it that the controller I have is not suitable for a PAS system. Your advice would be appreciated but please keep it simple as my tech knowledge is only basic I’m sorry to say.
Many Thanks
