A cool video about Kerry McLean who is the inventor of the Monocycle, a one wheeled motorcycle type vehicle. Filmed in 2006 by professional filmmaker Stephen McGee. Given my lack of ability to even ride a regular motorcycle there is no doubt in my mind I would crash the Monocycle. As Kerry says in the video this awesome machine requires a lot of concentration and skill to operate.

WOW I just fell off the couch trying to ride the dam thing by watching the video.

Very interesting 'niche' vehicle.

Very cool video and Mr. Mclean is quite an inventor and not bad a piano player either!
