Richter’s Rocket Bike: When An Engineer Attached Rockets To His Bicycle In 1931
In pre-war Germany, during the 1930s, there was no shortage of wild ideas when it came to transportation, especially when rockets were involved. From rocket-powered cars and aeroplanes to boats, motorcycles, and even skates—both roller and ice—engineers were fascinated by the potential of these explosive innovations. However, one of the most unusual and least practical applications of rocket power emerged in 1931 with Herr Richter’s rather daring Raketenrad, or rocket bike.
Imagine this: you’re at the famed Avus race track in Berlin, and instead of a roaring sports car or a sleek motorbike, what comes into view is a man on a bicycle—except this isn’t your average two-wheeler. Attached to the back are twelve solid-fuel rockets, designed to propel this ordinary bike into something far more extraordinary. The man behind this ambitious and slightly mad creation was a German engineer named Herr Richter, who apparently thought, “Why not strap rockets to a bicycle and see what happens?”
The result was nothing short of a spectacle. With a battery hanging from the top tube of the bicycle acting as the ignition system, Richter lit the rockets and set off down the track. Spectators watched in awe (and probably a bit of horror) as the bike accelerated rapidly, reportedly reaching a top speed of 55 miles per hour. For a brief, exhilarating moment, it seemed like rocket-powered bicycles might just be the future of transportation.
But as one might expect, controlling a rocket-propelled bike isn’t exactly an easy feat. Herr Richter soon discovered this the hard way when he lost control of the Raketenrad, tumbling off in what must have been a spectacular crash. Miraculously, despite being thrown from the bike at high speed, Richter was not seriously injured. The rockets may have been unpredictable, but Richter’s luck certainly wasn’t.
It’s unclear whether Herr Richter ever attempted another ride on his Raketenrad, though given the outcome of his first foray into rocket-bicycle innovation, one can imagine he might have thought twice about it. Around the same time, the focus in Germany shifted toward more promising rocket technology, particularly with the advent of liquid-fuel propulsion. Visionaries like Hellmuth Walter and Wernher von Braun were developing more advanced rocket systems, leading to revolutionary innovations like the Me-163 Komet and the V-2 ballistic missile.
While Herr Richter’s rocket bike never quite took off (pun intended), his adventurous spirit fit right into the era’s broader enthusiasm for experimental rocketry. Between the world wars, rocket clubs were popping up across Germany, the United States, Russia, and beyond, with enthusiasts eager to push the limits of speed and technology. Many of these early experiments used both liquid and solid-fuel rockets, the latter of which relied on the gradual burning of fuel to create pressure, pushing hot gas through the nozzle and generating thrust.
In hindsight, the rocket bike may seem like an eccentric footnote in the history of rocketry—more of a daredevil stunt than a serious technological breakthrough. Yet, it perfectly encapsulates the spirit of innovation and, frankly, the sheer boldness of the engineers and inventors of the 1930s. The Raketenrad may not have changed the course of rocket science, but it certainly gave Herr Richter a story to tell—assuming he could hear over the ringing in his ears after that wild ride!
