When does a bike stop being a bike? Apparently not when a rocket is propelling it to a world land speed record. French cyclist François Gissy used a hydrogen peroxide rocket engine to power himself to 163 miles per hour along an open stretch of road in Munchhouse, France, setting a new world land speed record in the rocket bike category, according to Road.cc.
You can check out a closer view of his start below. (The action starts at the 56 second mark.)
Before you try this at home, you should know that the hydrogen peroxide used in Gissy's rocket was at 90% potency, compared to the 3% variety sold at your local drugstore.
