Thanks all.  I'll give that a whirl and see if it kills the noise

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

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?
