Knobby Tired Purple Bike: Bounce For Glory

Peter William Wagner bounces across the fairgrounds at Maker Faire Bay Area 2011, delighting everyone whose path he crosses. The big purple eccentric-axeled bike has two inflated all-terrain wheels that can also function as flotation for the aquatic parts of the annual Kinetic Grand Championship in and around Arcata, California, where this “whim-cycle” has appeared for the last six years. Even Peter’s baby granddaughter enjoys the ride.
