So I made my own electric mountainboard. I used and MBS Colt 90. I rode it for many kilometers without any problems.
But the wheels are very unbalanced. I balanced them with weights and that improved the riding experience a bit, but the tires are also not round at all.
Here’s a video of one of the wheels. All of of them are pretty much the same.
I can go up to 20km/h quite comfortably but I can feel the wobbles almost constantly at any speed. Is this normal? Is there a way to make them more round?
I inflate them to 3 BAR.
