When he's not racing 125cc baby strollers, Colin Furze, a plumber by day and mad inventor by night, is likely to be doing something even more mad. Take, for instance, his most recent project: building what he calls a "big-a** pulse jet."
Of course, once you have a pulse jet, you can't just let it languish in a shed. Which is why Furze decided to rig it up to a woman's bicycle that used to belong to his friend's mom, Norah, for whom the bike is now named. It has a certain ring to it, no? And Norah the Jet Bicycle is hot. Literally. Furze had to lengthen the bicycle not just to fit the jet, but also to keep the rider away from the heat.
"Had I binned the pedals idea, yeah, it could have been shorter, but the heat this thing chucks of is intense, and at times I've struggled to turn a valve of 40 centimeters away from it, so sitting on top of it would need some sort of heat shield, and I think it would start to look less bicycle like," Furze said on his Web site. "With all that in mind, we cut and stretched Norah by around a meter."
The gas bottle that fuels the jet sits just behind the rider, and is operated with valves. It has a few issues -- to go to full throttle, you need to wait until the jet is hot enough, but you can't idle waiting for it to heat up, because it will melt the bicycle tire -- so you can't just zoom off straight away. The bike itself is also really rickety and unstable.
But, as Furze said in his inimitable style, "Yes, we could have cured it with better frame better wheels etc, but I like it's a s*** bike [and] still is."
You can see it in action in the video below, and head over to YouTube to find out how Furze made the jet in the first place.
