When I built my rear hub motor MTB, I used a Freewheel kit. The original unpowered wheel hub was a Cassette type. It works perfectly, but the only issue was the Freewheel hub (wheel) was slightly wider at the axle than the Cassette version.

Dirt bike not E-Bike. I was using the o-ring/x-ring analogy.

I replace my dirt bike x-ring chain when the links become tight and/or the sprockets become hooked. Usually after about 30-40 hours of moderate riding. They certainly don't last more than 500 miles.

Ok, fair enough. Good luck with fixing the moped using the tips above ^ I think it might help if you post a photo of the whole moped?

You must be kidding, or else a troll. I'm out of this thread.

It's hard to say, depending on your skill level and how damaged they are. I've used a thread file but he also used a Wheel Stud Hub Thread Restorer**M12 x 1.25**M12 x 1.5**M14 x 1.5mm 3 Dies to repair threads. You will definitely need new nuts, and each time you thread the old ones back onto...

In post #3 the 3rd and 4th photographs both show significant damage to the threads on the fixed axle. I doubt that you will be able to tighten the nuts sufficiently, no matter how many locking washers, torque arms and split washers you put on, in order to stop the torque twisting the wheel out...

Funny, but I was looking at that too... I lust after a '60s rangefinder..

Well, I've got the front and rear light on order. Will let you know my thoughts once they've arrived...

Mornington Crescent :cool:

It'll be fine. I converted my ally with a 1500w rear hub motor.

I didn't think of the creak :) too early in the morning.

I'm not sure I understand how the spokes make a noise? Can you post a video clip from before you initiate the wheel turning up to the sound becoming evident?

Don't use a round file! Use a Flat file, since you do not want to round out the corners, other than to match the profile of your axle. The idea is to have as tight a fit as possible - you can take away material, but not add it back (easily...) Cut a piece of 5mm aluminimum, and trace your...

If your brake disk is correctly aligned on the left side, don't add any washers to that side.

I spread my aluminium stays apart using a tyre iron to wedge my hub motor in with the additional washers. No issues at all ...

Add another washer, the steel chainstay can definitely handle it. Reindex the gears after adjusting the end stops.

Is this a conversion, or shop bought? Usually the former requires a complete reindex and stop limit adjustment. If it is shop bought, then take it back for a service. If you want to try yourself, then see below YouTube. Usually with a crank motor, the chaingear wears relatively quickly and...
