Michael Robert Ryan Posted March 11, 2021 Share Posted March 11, 2021 (edited) New rider here. Bad wobble starts at about 20 MPH and I nearly wiped out and bit it. Is it me or the EUC? Wheel seems a bit out of true, tire a bit eccentric, but it's no worse than on bicycles I've owned that never gave me any trouble.

Tawpie Posted March 11, 2021 Share Posted March 11, 2021 Speed wobble usually goes away as the pilot gains experience and gets the necessary muscles in shape. But it is affected by tire pressure so muck about with that (probably lower pressure). Try carving and most importantly, try to relax and not be tense and stiff. But if the tire isn’t running true, it won’t help you at all. How does it look when you free spin it? (turn it on, put it CAREFULLY on a stand and let it wind up to full speed and shut itself down) 1 Quote Link to comment Share on other sites More sharing options...

Tawpie Posted March 11, 2021 Share Posted March 11, 2021 (edited) Carving is going side to side like a skier instead of just following a straight line. I’ve read the wobble tends to happen because the wheel is “perfectly balanced” and has a chance to set up oscillations as a result. Carving keeps your weight moving right left right left and that keeps the oscillation from starting. Free spin is basically getting the wheel to go to its max speed while you’ve got its tire in the air (so it doesn’t go anywhere and also so it has minimal load on the motor). If you disable the lift switch and pick up the wheel, it’ll spin to its max speed and then beep and stop. Alternatively you can set the wheel in a stand being careful that the tire isn’t touching anything, then steady the wheel and turn it on. It allows you to see the wheel spinning which makes mounting problems pretty evident. But be cautious when free spinning—there’s a lot of energy and gyroscopic and torque forces in play and you don’t want the wheel to touch the ground and tear itself out of your hand etc. Edited March 11, 2021 by Tawpie 1 Quote Link to comment Share on other sites More sharing options...
