Should I be concerned?
Been loving my bike, but today I noticed on my ride that there’s a sort of weird whirring in the back tire that I notice at higher speeds. It stops when I brake, and only seems to come up when I break 23 MPH. I don’t think it’s anything to worry about, since nothing seemed obviously defective with a cursory glance.
Edit: I have an XP4 750w Pine Green. Tires, wheels, and brakes have not been replaced. Seat post and seat have.
