The World's First Human-Powered Skateboard!PUMGO is the world's first human powered skateboard. There's no need to push; just PUMP and GO! You never have to put your foot on the ground to move the PUMGO. Just rock back and forth on the board, an off you'll go!Like regular skateboards, PUMGO has a regular sized 7-ply deck and four wheels, but that's where the similarities end. These boards are completely push-free, which allows you to drive the board forward simply by pumping the deck. A unique mechanism transfers this motion through a 4WD system that then propels the board. Not only is PUMGO fun, its great exercise!PUMGO was voted a "2004 Sports Product of the Year" by the Sporting Goods Manufacturer's Association.
