Mine cut off semi-randomly a couple dozen times when I was well past the 300 mile mark. The worst/most annoying cases would be when trying to re-engage it when the traffic light would go green, but the onewheel wouldn’t re-engage and it’d just look like I was tripping forward in traffic. I’d have to step over to the curb and restart it a couple times before it ‘worked’
It was definitely the most fun I’ve ever had commuting, but the fact that I couldn’t trust it to simply just not shut off on me in traffic made it feel pretty impractical.
Apparently a couple causes for this could have been a bad battery and also a bad footpad. For now, I’m just sticking with my ebike, since a battery failure there is a bit less catastrophic!
