French Cyclist Sets 333 km/h Speed Record

French cyclist Francois Gissy has long been riding rocket-powered bikes but he broke his own world speed record last Friday when he reached a heart-pounding 333 km/h (207 mph). The bike, from Exotic Thermo Engineering, was designed by Gissy’s friend, Arnold Neracher, and was powered by highly concentrated hydrogen peroxide. Watch the video below.
