Rocket-Powered Bicycle Does 263 KM/H [Video]
Of course, you need to do some modifications to the bike, and install a rocket engine: François chose a Swiss one manufactured by Exotic Thermo Engineering, running on liquid hydrogen peroxide. Yes, the one you can get at the corner drugstore, only way more concentrated: 90 % versus the 3% in the convenience store bottles.
The engine breaks the peroxide (H2O2) down at high temperatures and generates high-temperature steam, so this is not the kind of tinkering you'd do in your backyard. The process happens at 650 F (343 Celsius) and it's obvious that toying around with rocket engines is not exactly the safest way for non-professionals.
While the previous landspeed record was around 150 mph (242.6 km/h), François Gissy and the Swiss rocket-guys managed to pull a nice 163+ mph (263 km/h), changing the books and opening a new door for the thrill seekers. And yes, it looks like the Ninja guys will no longer be a concern for François Gissy. Talk about rocket science...
