Bike with Jet Engine

Postby Jet Bike » 23 Nov 2015, 5:43pm

I bought a bike to cycle with my son this summer and recently I had this crazy idea to use my bike as a test bench for a turbine engine. A bit of fiddling and two weeks later here it is.

Ill upload a link to some video footage shortly.

There's no such thing as a tailwind.
It's either a headwind, or you're going well.

Mine is a bit more sedate than that cycleruk, and possibly more practical if there is such a thing 8) .

here is the first video i took yesterday.

quite interesting watching the three videos - three very different takes on the theme - love that Colin Furze, wonder what would happen if he teamed up with Guy Martin sometime?

Brilliant, just need an afterburner now for when that following car gets too close. :wink:

Reminds me of the chapter in Frank Zappa's autobiography entitled "How I Almost Blew my Nuts Off."

Here is the second video. At around 40mph the steering felt a bit shaky might need a steering damper, or maybe it was me shaking because I was so cold. i reached 45mph and was still accelerating but didnt push it any further.

Can you estimate it's fuel consumption? Just for my interest, I expect it will be utterly dreadful.....
Pushbike hardware (chassis, steering, tyres, no suspension, bike brakes) really aren't anything like sensible for 45/50mph, I'm relieved you made discretion the better part of valour.... :)

This surely can't be legal on a public road?

This odd documentary also features a rocket-powered bike (trailer here):

(although can't remember if it really 'powered' the bike more than creating an exciting tail of flame, which in my book is also good).

not rocket powered, but I think my favourite "assisted" bicycle ever....

I know this is just a bit of fun but you have , in effect, entered the world of motorcycles.
The cycle helmet is unsuited to speed tests around 40mph, you will be wanting a motorcycle helmet (and leathers) to protect you in case of a fall. That fall seems much more likely than on a motorcycle because your bike hasnt got the right handling potential and the thrust is coming from a location likely to destabilise.

Add to that, if an unfriendly copper is called to the scene, you can have a few chapters of the book thrown at you, for riding a motorcycle without everything.

Despite those words, it is nice to see somebody doing something novel by themselves.
