Shift tricycle bicycle

The Shift bicycle is a kid's training bike with a unique design: its paired back wheels splay outward when the bike is at rest, and are drawn inward by an articulated hub when the bike is in motion, mimicing a single wheel. The device won its American designers Scott Shim, Ryan Lightbody and Matt Grossman, top honors in last month's bicycle design competition held by the Taiwanese government.
