Hi there. Had my bike for just over a month and noticed a sound in the rear. Nothing is rubbing and it still does it when I remove the rear break. It's a high pitched squeak. Not really a grinding sound at all. It does it even with the slightest movement even. I can rock the rear wheel like a DJ and it does it even. At first I thought it was just the break rubbing after I slightly adjusted the free movement at the handle. But it wasn't that at all. Do E bikes normally make noise or do they spin quiet? Should I be at all concerned?
Sometimes the rubber hub bearing seals can do that. Hard to diagnose online but that my 1st idea.
It is a squeaky rubber sound. I was going to say that in my post. But the as the tire is not rubbing on anything I didn't say that. Is it normal? Or should they have lube on them so they don't tear or melt from the friction? Thanks
This might be the same squeak-squeak problem I had with the front wheel of my MiniST - Rad support helped me diagnose and fix it over the phone. It correlated with wheel rotation but not application of the brake, or not.
As Radio Runner said, there is a rubber bearing seal on the outside of the wheel to keep dust and gunk out of the wheel bearing - it lightly rides on the brake disc as I recall and looks like a little black coolie hat, sort of truncated-conical. Rad had me apply a tiny bit of light oil under the lip of that seal and rotate the tire to distribute the oil - problem solved and hasn't returned!
Just a very tiny bit of oil is all it takes, the smallest amount you can apply with a fingertip - you don't want to get excess oil near your brake system.
Hope this does the trick for you.
Thanks all. I'll give that a whirl and see if it kills the noise
