Recently my Onewheel GT started getting error 15. I thought it was going to be an easy fix but I was wrong. Now I have to send in my onewheel gt to future motion for repair. let's hope it doesn't cost too much.
I'm afraid nothing that might soothe you. I sent it in for repair and was given a $897 quote to repair 3 things. I ended up trading it in for the credit ti get a GTS. Even though I didn't want to do that, I'm happy I did. The GTS is amazing. I'll share a video on that soon.
