A New Bicycle Design

Here's a truly great stroke of genius to solve the problem of teaching a child to ride a bike.

A new tricycle-bicycle design could take the fear out of a child's first solo two-wheel ride. Three Purdue University industrial designers have built a bike that ditches the training wheels, but keeps rookies stable. It's called the SHIFT. Under the new design -- a tricycle slowly transforms to a bicycle configuration as the rider pedals faster, then returns to trike formation as the rider slows down.

Here's a picture of the bike.
