Francois Gissy prepares for his world record attempt

On May 19 of this year, Francois Gissy claimed a new land speed world record by reaching 263 km/h (163 mph) on a rocket-powered bicycle. Now the flying Frenchman has gone even faster, hitting a peak speed of 285 km/h (177 mph) in just 6.7 seconds, making it the fastest anyone has ever ridden a bicycle.

The 285 km/h run took place at Interlaken, Switzerland, on October 7 on just 790 m (2,590 ft) worth of usable track. The acceleration phase of the Hublot-sponsored run took 350 m (1,148 ft), with the remainder of the track required for braking.

Gissy was straddling a canister of concentrated liquid hydrogen peroxide that provided the fuel for the rocket on the record attempt, which also saw him do the quarter mile (402 m) in 7.3 seconds. His rocket-powered ride outdoes the 268.8 km/h (167 mph) achieved by Fred Rompelberg slipstreaming behind a dragster in 1995, which if certified, will make it the fastest anyone has ever traveled on a bicycle.

The video below shows the run wasn't always smooth riding, with the vibrations from the rough track causing the rear axle to loosen significantly.

It's not a bicycle if it's got a rocket engine! It's a rocket propelled motorcycle, surely. Was he pedalling at 177mph? If this record stands it's a triumph for stupidity not derring-do! If he was catapulted on a bicycle that would be OK, but you cannot have a motorised, rocket-propelled or anything propelled machine and call it a bicycle, even if it has bike gears and brakes.

Nothing like straddling a bottle of organic acid be twine Ur legs. Cool record and good nothing went wrong as the pilot would have suffered some horrific acid burns. Most likely died having the lower part of the body eaten away. So brave pilot :D

A perplexifier as many articles are on gizmag, but quite an accomplishment.

When I climb up on Santa's knee next month, I'm going to tell him that I have been good all year, and I would like to find one of these under the tree on Xmas morn. Ralph L. Seifer, Long Beach, California.

I bet his insurance company loves him for the HUGE premiums he must pay!

Sorry "Master" but "bicycle" simply means "two wheels" NOT "pedal-powered"

Nutcase, I think Master-guy is right. There is a reason he mounted pedals and a chain on the vehicle even if he does not use them. I think his machine is qualified as "bicycle with motorised support". The word you are looking for is "two wheeler" as bicycle actively revers to it being propelled by human power.

That feat deserved a better Video coverage, even a local Marriage and event covering Video Reporter,from a Photo Shop, would do better.

He isn't the fastest person on a bicycle - I saw on Discovery an american being pulled by a car on that salt trail in the desert - he reached 300 km/h, but was not "self"-propelled, if you can say that about a rocketcycle

Isn't there a faster way to get to the grocery store and back before the ice cream melts?
