For the last four and a half years, [Anders] has been working on a motorcycle project. This isn’t just any old Harley covering a garage floor with oil – this is a gas turbine powered bike built to break the land speed record at Bonneville.
The engine inside [Anders]‘s bike is a gas turbine – not a jet engine. There’s really not much difference in the design of these engines, except for the fact that a turbine dumps all the energy into a drive shaft, while a true jet dumps all the energy into the front bumper of the car behind this bike. [Anders] built this engine from scratch, documented entirely on a massive 120 page forum thread. Just about everything is machined by him, bolted to a frame designed and fabricated by him, and with any luck, will break the land speed record of 349 km/h (216mph) on the salt flats of Bonneville.
As with all jet and turbine builds, this one must be heard to be believed. There are a few videos of the turbine in action below, including one where the turbine drives the rear wheel.

As a kid, [Tom] followed all the automotive land speed record attempts on the Bonneville Salt Flats. The cars used in these attempts were all built by guys in their garages, and as a bicycle frame builder, [Tom] is keenly aware of the land speed record for bikes. One thought leads to another, and [Tom] decided he would see how fast one of his frames could go.
Aside from a gigantic gear for his custom bike, [Tom] also needed a little help from a friend. The current land speed record on a bicycle was done by drafting behind a drag racer. [Tom] doesn’t have a drag racer, or a wide expanse of flat open ground in his native England, so he did the next best thing: drafting behind a Ford Zephyr on an abandoned WWII airstrip.
On the runway, [Tom] was able to get his bike up to 80 miles an hour. Wanting to see how fast he could go in ideal conditions, the bike was taken to the garage, put on a pair of rollers, and measured as it was brought up to speed. With a lot of effort, [Tom] was able to get up to 102 miles per hour, incredibly fast for something powered by human muscle.
