Thanks for this video it really helped me right now to service my motor, thought it was complex but I did it and eliminated the weird noise I was hearing

I was looking at you tear my wheel apart. Its exactly the same except for the tyre brand. I suspect there is a problem with mine too, so best I take it off and have a look. Thanks for showing us how.

Dude! How old is the bike??!! Regular maintenance is the key to longevity like everything else.

Tip: Have an old speaker near to hand for keeping bits safe as they come off. Just stick them to the magnet, a quick win!!

When I first learned these motors had nylon plastic planetary gears, I thought I might swap them out for steel gears. After some time to take my motor apart, it appeared to me that the gears are not so difficult or expensive to replace when worn and the nylon plastic gears are much quieter than the metal gears. I think you've done a great job on your videos showing us how these powerful little motors work and can be serviced back to good as new again.

Thanks as always for the kind words - they can be replaced in around an hour if all goes well and you don't have to clean *too* thoroughly*

I intend to change the bearings of my motor, the one on the cassette side is shaky while the other is perfect, the only issue now is how to get it out as I don’t have the right tool, do you think is should just let the bearing stay?

@EbikeRepairs 2 ай бұрын

Your local bike shop should have a bearing extractor, you could ask them for help? It makes sense to change it 'while you're in there'

mine is doing a similar noise to the left side but wheel spins as normal when motor is not engaged but soon as i peddle even with motor off the noise come back also my disc brake come loose as soon as it started i thought that was the noise till i tighten it back up so im thinking its the bearing closest to disc brake has given up after 3 year/ what are your thoughts?

after taken apart im afraid it was the gears it has the odd tooth iver missing or warped looks like most of grease has dried up

How is the throttle thing you used to text the motor designed? I would love to make one for my shop.

It's just an old ebike controller, brainpower with s866 display with integrated throttle...

I experienced a problem that suddenly the direction of the BLDC motor's rotation changed so that the motor rotated but the wheels did not rotate. Has anyone ever experienced something like that?

@EbikeRepairs Ай бұрын

Sometimes self learn wires on controller have shorter and need re learning I correct direction

@Boediprasetya Ай бұрын

@@EbikeRepairs My controller doesn't have a self learning wire. the only thing there is is a cable to the BLDC motor/hall sensor and to the SW900 LCD monitor/break sensor with a Julet connector. I use a BLDC rear hub. I have replaced/bought the controller 3 times and the last time it worked normally. Thanks Bro

I recently bought a rear hub motor from ebay, but the rear cassette won't spin backwards after tightening it onto the hub, any ideas what it could be? it spins freely off the wheel but as soon as i tightening it i locks solid, and won't spin backwards, the company sent a replacement cassette and that one is doing the same problem, any advice would be much appreciated.

@EbikeRepairs 3 ай бұрын

You need a spacer behind the cassette! Bottom bracket shims work perfectly.
