Invented by Curtis DeForest
, this sci fi-looking gizmo has its rider standing up between a pair of cambered eight-foot wheels and pedaling with both arms and legs.
It can "easily" hit 50 mph and it much harder to tip over than a regular bike (and doesn't kill your sperm count, either). NASA is interested
in it for low-gravity environments.
