Di-Cycle is a remarkable concept that was recently unveiled at Bicycle Exhibition 2008, Designhuis in Eindhoven, the Neatherlands. The motion of the driver much resembles to that in the paddle boats – of paddling the pads horizontally opposite the driver’s seat but at almost the same level. The giant, spokeless wheels traverse the road like regular bicycles and would act as manual ores on water surface. There’s no threat of loosing balance on this one as the wheels completely bear the weight of central mass so that even toddlers could enjoy the ride of the Di-Cycle.
