Watch This Guy Go From 0 to 207 MPH In Under 5 Seconds On a Rocket Bicycle (Video)

François Gissy is a bike enthusiast with an insatiable appetite for speed.

In May of 2013, the French daredevil set a bike land speed record by reaching a top speed of 163 mph (263km/h) on his rocket-propelled bicycle.

Gissy smashed that record this past Friday (Nov. 7), hitting speeds of 207 mph (333 km/h) while dusting a Ferrari 430 during a test run at Circuit Paul Ricard in southern France. The most incredible part: he reached that top speed in less than 5 seconds!

Check it out in the video below:

The rocket thruster on Gissy’s bike, which was built by Swiss firm Exotic Thermal Engineering, is powered primarily by hydrogen peroxide.

Andrew Tarantola from Gizmodo explains the science behind how it works:

“Concentrated liquid hydrogen peroxide (H2O2)—about 90-percent concentrate, compared to the 3-percent stuff sold in drug stores—is fed from a storage tank into secondary chamber filled with a catalyst, typically silver.

This causes the chemical bonds to break down and the hydrogen peroxide to decompose into heat, water (H2O) in the form of 650 degree F steam, and oxygen (O). The steam is then forced through a rocket nozzle to provide thrust.”
