Po-Chih Lai is a recent graduate of the Royal College Of Art. For Show RCA 2012, the Design Products student exhibited "The Stair Rover," which modifies traditional skateboards and makes them more adept at bombing stairs. An extra wheel is added to the corners and a flexible chassis steadies the board on uneven surface. [Deezen]
