Ben J. Poss Gulak and His Uno 18-year-old Ben J. Poss Gulak invented The Uno. It caught our eyes because it's a one wheeled-looking motorcycle, actually its balanced by two wheels set up side-by-side and its footpegs. Operation of the 54.4 kg (120 lb) machine is simple, in fact it's so simple there are no controls except for an on-off switch. To go forward you simply push your body weight forward to tilt the machine. To back up, just lean back on the seat to tilt it backwards and back it goes. It reported by Mojo magazine.
