US$1,690 monovelo.com
This 21st century hamster wheel for humans takes the relationship between man and the all-mighty wheel to a whole new level. Riders sit at the centre of this pedal-powered contraption and steering is taken care of by the shifting of body weight. The Monovelo was used in the opening of the 2008 Beijing Olympics and you can even nab a glowing LED model for nighttime riding – you know, just in case you didn't think you were going to stand out enough.
