I have a problem with my TSDZ2 motor, it suddenly has very little power when pedalling or when using the throttle. I can pedal or throttle very lightly to build up speed but the moment I put some effort into it there’s a horrendous loud friction whine that comes from the motor. I can feel the motor trying to grab but it’s not quite able to, it spins but the crank doesn’t move any faster. Here’s a short video of what’s happening when I use the throttle only. https://youtube.com/shorts/-ujgU_7KKN8?feature=share
Now I can tell you the moment it happened, I was walking the bike up a few steps and decided I’d use the throttle to help me - because why not I thought. After that I noticed the whining noise when pedalling and things quickly got worse from then on.
I replaced the sprag clutch thinking it must be that but it’s made no difference. I had a metal gear (not the blue nylon one) fitted to the motor at the time. I’m thinking because it didn’t fail here like the blue one might have, the stress has been transferred somewhere else in the motor and caused damage elsewhere, but I just don’t know where. I’ve also put the original blue gear back in just to rule out any chance the metal gear could be the issue. I can’t seem to find any reference to this same problem anywhere in the universe. Any help will be greatly appreciated, I’m out of ideas.
