I purchased a OneWheel, gently used for less than 10 miles, from a coworker a few months ago. I haven't had the time to play with it for more than 20 minutes of trying in vain to learn to ride outside my apartment one day. Between travel and health issues, I haven't been able to play with the one nice thing I've gotten myself all year. It's very sad, but my health issues have now impacted my employment and I need to sell the OneWheel.
I'm open to offers, I paid $1200 + shipping and the OneWheel hasn't seen more than a few hundred more feet of use since than.
