Frenchman François Gissy has laid claim to a new land speed record using a rocket-powered bicycle. Yes, you read that right. A rocket-powered bicycle. Gissy and his bicycle managed to hit a mind-boggling 163 miles per hour (263 kilometers per hour) over a vacant stretch of highway in Munchhouse, France over the weekend.

The rocket was built by Swiss company Exotic Thermo Engineering, and it provides its thrust using liquid hydrogen peroxide – much more concentrated than what you'd find at your local drug store, so don't go trying this at home tonight – that is broken down to generate steam at 650 degrees Fahrenheit.

Watch Gissy's record speed run in the trio of videos below, and take special note of the speeding cars and motorcycles he lines up against in two of them.

      What speed rating are those tires? slight steering input would send you into the fields. That guy is nuts!

      you know you've got it bad when your car gets absolutely spanked by a man on a bicycle, truly a sad day for sti owners.

      I'd never let an experimental rocket fuel tank sit two layers of fabric away from my jewels. That's just nuts.

      Not terribly impressive when the fastest pedaled bike was 152mph (drafting a car)

      163 mph on spoke wheels and bicycle looking tires. He's got balls.

      Holy Crap! That guy has more cojenes than imaginable. Can anybody fathom what that speed feels like on a skinny-wheeled bicycle?
        • 2 Years Ago
        Balls of Steel! What I am curious about is where did he get bicycle tires that could take that much punishment?

      I dunno if I would put my nuts so close to that thing....

      I did something similar (well, not quite) a few years ago by strapping a leaf blower to the rear rack of my bicycle. I hit 10 mph on a level road. Fun time!
