There are two types of rocket bike: a manual cycle with added rocket power (or what appears to be rocket power) and a motorbike with additional power. They are often thought of as stunt bikes, because they lack deceleration and are impractical for the highway, but stunt bikes is its own category, which just happens to also not be street legal. While most stunt bikes you won’t see on the road, it’s definitely just as well that you will not see a rocket bike of any description on the road.
Early Rocket Bikes:
Early versions of the Rocket bike include Germans Fritz von Hopel, and Richter. Fritz von Hopel bolted six booster rockets to what was a 22hp (horsepower) motorcycle called “The Monster,” but he was stalled by the German government. He finally created a rocket powered motorcycle in 1929. Richter in 1931 had a less than successful test run; his bike exploded. This was also in Germany.
Rocket Bikes Today:
You might expect that we have mastered the skill by now, but the thing about being a stuntman is that things can always go wrong. It’s best to always be prepared. Names currently associated with rocket bikes include Eric Teboul, Francois Gissy, Fred Rombelberg, Rick Jojatt and the most famous, Evel Knievel.
So, let’s take these doers of daring-do one by one.
Eric Teboul who gained the nickname “Rocketman” by achieving speeds of 220mph. The bike ran on hydrogen peroxide which is broken down into oxygen and a massive cloud of steam, coming out of its exhaust nozzle. It will accelerate until it runs out of fuel.
Francois Gissy sped up to 207mph, the bike was made to be lightweight, looking more than an e-bike rather than a motorbike. Silver powder provides the “secret ingredient” to the thrust. He also developed a bike which had a speed of 249mph called “The Spine Crusher” though it is difficult to maintain such speeds.
Fred Rompelberg reached a speed of 286mph, though it had to be towed by a racecar for a bit. He achieved 0-60 in 11 seconds in a home-built rocket bike.
Most infamous is definitely Evel Knievel whose rocket bike was developed by experts including US Robert Truax. The goal was to jump the Snake River Canyon. The jump took place September 8, 1974. It’s a little hard to think of a rocket bikes taking off at a trajectory, but not flying as such. As long as there is no wings it’s a power assisted jump—not a flight.
Technically the bike cleared the canyon, but a parachute was deployed too early; the high winds affected the trajectory causing a technical fall. The bike reached speeds of 250mph; he was lucky to have survived.
Rick Jojatt known as The Human Fly used rocket power to jump 27 buses. He may not have appreciated the fame as he disappeared soon after achieving the stunt.
What is the fastest speed of anyone on rocket bike?
The leader has changed hands several times. In 1999, The Mach 3 Challenger (sponsored by Gillette) piloted by Richard Brown achieved a speed of 365mph. Then along comes Rocky Robinson with a bike called “Jet reaction” which was powered by a gas turbine achieved a speed of 376 mph.
Several bikes are lined up with over 425 pounds of torque to make attempts at breaking the 400 mph mark, we’ll soon see.
Is it about the records? Francois Gissy says that when he gets old he may settle down to the comfort of a motorcycle. This is the kind of people we are dealing with; those who think the speed of a motorbike is too geriatric.
