07PG2 - Photon Gen 2: Motor noise

Symptoms

Motor sounds abnormal. 

Troubleshoot

If the noise persists, please follow the steps below to troubleshoot the issue and find the source of the noise:  

1. Kindly turn off the system and rotate the rear wheel backward. Please check if the rotor is rotating smoothly.  If there’s no noise from it, then there’s no issue with the gearbox and drivetrain.  
2. If there’s no noise under no load, please remove the 219H chain and tensioner and proceed to run the motor, if it produces noise, then the noise is within the gearbox.  

*Please note that when you rotate the rear wheel backward, the center of the motor (rotor) should be rotating. When you push the pedal and the system is turned off, the rotor should not rotate.  

Solution

Contact CYC or your local dealer for further advice and replacement if needed.
