Jet Engine Bike
The archived story of the day I mounted a miniature diesel jet engine to a bicycle.
One day I found a miniature jet engine online and immediately wanted to understand it. I bought it, used it as a demonstration at school and then started wondering what else I could build around it.
The answer I came up with was a jet-powered bicycle.
Mounting the engine
I attached the engine using aluminium straps and sturdy threaded fasteners. It ran on diesel, so I fitted two 250 ml tanks. The original setup gave me roughly two to three minutes of runtime.
The engine included a telemetry display. I mounted that on the handlebars so I could monitor it while the engine was running.
The test
With hearing protection in, I started the engine. It produced the sound, smoke and heat you would expect from a tiny jet. The original post reports that the bicycle reached about 60 km/h during the experiment.
It was exciting, but it was also clearly unsafe. This project belongs in the archive as an unusual experiment—not as something to reproduce on a public road.
