Uno motorcycle.
A while ago a friend/colleague of mine and I did some concept work in the moto industry. For sh*ts and giggles we played around with the idea of a one wheeled motorbike full of gyroscopes like a
Segway, and eventually made a concept bike (Ducati branded of course). Well, some 18 year old made one it looks like. Ass ugly, but they say it works.
