Some noise from rim or hub

Q:After running for a couple of weeks.Sometime you can find there is some noise from bicycle rim while you are riding.

A:Now you should check spoke nipple.If can’t find 36 pcs nipple on spokes.There must be some nipples inside the rim,if not,maybe some aluminium impurity.

Solve:Disconnect your hub motor wheel from your e-bike,remove the tyre,you will find there is a red gasket round the rim,also take it off.Then make the valve hole down,shake rim,the impurity will be out of the rim.Re-install them.

Solve this noisy problem.

Advice: We suggest after running several days,had better to tight 36 pcs nipples.

Q:Can you help me?I am very disappointment.
I ordered a motor from the other supplier,the HBS36F — Front Motor.Sent several emails,haven’t gotten any reply in 2 weeks.

I have just tested it and it makes a noise once every turn and it gets stuck (or at least much more friction) at the same angle. It feels like it could be some magnetic effect but more likely it´s some mechanical contact that´s disturbing the rotation. Have you heard of this problem before or is the electric bike motor constructed to act like this? Could we do something to fix it, like open it up and remove whatever that´s making the noise?

A:The noise comes from some metal impurity on the magnet.

Solve: Disconnect hub and remove it
