You know, the two wheel standup vehicle. lean forward go forward, lean backward, go backward. Very fun machine. 5 grand a pop, I don't think I will have one anytime soon but if I were very wealthy........Anyone else ridden one???? Tricky at first, but if you relax and don't get too jerky, very steady leaning, I almost had it mastered in less than a couple of minutes. Very, Very coool!!
