Hello, I had trouble with my second cheap chinese unicycle.. problem was: When I push "on" button, unit goes inclined. not perfectly straight. So after communication with the seller, I have the solution and make a video for you. I don't know if this reset manipulation can correct other problem.. But for this balance problem it's just magic!
