Whisk

Whisk is a modified bicycle that is apparently as stable as a bike, and won a finalist position at the 7th annual Taiwan R&D bicycle design competition in 2003.

Combining the agility of a unicycle with the stability of a bicycle, Whisk is the ultimate inter-city commuting vehicle…Maneuverable enough to ride on crowded city sidewalks and small enough to carry on to mass transit or store in the trunk of a car.
