My geared hub motor, front wheel 500W, bought from Ali about a year ago has developed a problem! When I apply the throttle it has a rattling sound and barely moves. Sometimes it comes around after a while and then works for the rest of the trip.
I'm pretty sure it's the freewheeling clutch that is the problem, altough I can't see anything wrong with it?! Everything inside this motor looks like new, which isn't surprising because it has only gone 800 km.
The clutch works as it should when tested by hand but of course it has to handle much more torque when used with the motor...I even took the clutch apart and checked/cleaned everything, lubed with oil and welded back together. Only difference now is the rattling sound is not as harsh, slips just as much!
Well, any suggestions on this? Is it a common problem? Should the clutch be un-lubed to work as intended?
