designer's own words:
The Sideways Bike is a two wheel steering bicycle with independently steerable wheels that travels sideways. This steering arrangement affords a unique and distinct motion that is both entertaining and graceful; much like the motion of a Snowboard. This Sideways Bike is an instrument of fun/play and is best suited for children from age 7.
The Sideways Bike is recognizably a bicycle, but it is recognizably different.
