Recently I have noticed a weird noise coming from the axel of my Nikola Plus. It almost sounds like its its the tire rim itself. It seems to make a noise right as the air pressure valve hits the 6 o'clock position. This literally just happened today and is now noticeably loud enough when I and just walking with my EUC. Seems to be getting worse and louder. Actually is louder when the wheel is turned off.
It is not the normal motor noise from stopping and starting. I know what that sounds like and this is not that. I have not have any crashes or falls. When I am standing on the wheel and picking up speed I do not hear anything. If I do a spin test I do not notice it either, maybe because the wheel is rotating too fast.
Unsure if it is safe to ride and do not want to break anything. Sounds like it needs a good cleaning and some WD-40.
PLEASE HELP! Videos below....
