Gissy developed the bike with help from Swiss company Exotic Thermo Engineering who made the hydrogen peroxide powered propulsion unit.  Speed was measured with a GPS unit on the hydrogen peroxide powered mountain bike, reported French news agency AFP.

In the understandably short video, Gissy holds on for dear life as the rocket powered bike – blasts past a car on the runway.

The unverified 263km/h (163mph) – other sources suggest lower speeds of 180km/h and 163km/h – would still shy of the 268km/h achieved by Fred Rompelberg, who was motor-paced to the absolute bike speed world record in 1995 on salt flats in Utah, America.
