    To hell with internal combusion or electric assist...

    has anyone actually tried a pulse jet or turbojet assisted bicycle? It would be completely and totally impractical, but I can only imagine it would be a great deal of fun. Pulse jets aren't too hard to build, relatively speaking.

    Has it been done yet?

    Wouldn't a bicycle with a motor be a motorcycle? Anyway, a pulse jet is a type of ramjet and must be accelerated to a fairly high speed before it will function. The German V1 "buzz bomb" was powered by a pulse jet after being launched by a detachable rocket engine. A turbo jet is more versatile but more expensive, complex and heavier. Strapping a RATO bottle to a bike should provide a lot of excitement.

    To an extent, I suppose. But think 1970's and 1980's mo-peds, which really were more like bicycles with engines on them. Except those had some level of practicality. This would be something odd just for the sake of being odd.

    Anyways, a small pulsejet can be kicked off with a leaf blower or other high-volume air source.

    I've seen the video of two such experiments, I think on YouTube. If interested, search for it there. The one used a model airplane jet (turbine, not pulse, jet as I recall) and had video of it being ridden.

    I believe they are inordinately loud, for one thing.

    Here's one of them:

    Not impressive speed in the video, but these are real turbines and take RC model jets to 200 mph.

    I'm still making plans with some friends to build a pulse jet powered go kart by the end of 2008.

    I'll most likely end up in the burn ward, not the ER .

    Ron Patrick put two JFS 100 jet engines on his wife's Honda Scooter (scroll to the bottom):

    Kind of heavy to use on a bike though.

    Well, it seems that the thrill of these engines is that they can create soo much power. Making a small version defeats the purpose. I'd be inclined to just go for a two wheeled vehicle that could handle the power.

    Well, since you ask, I did try a jet engine experiment. Keep in mind that I'm a Navy aircraft carrier veteran, and I have a flame retardant uniform.
    Should I show a picture of the bike? It's the same bike that's in my avatar.

    Anyway, I tried building a fire inside the fairing, on the theory that expanding exaust gasses would help propel the bike.

    I found that there is forward force (propulsion) if I first pedal the bike to at least 12 MPH.

    I had it going good one night, with a fire in an aluminum baking pan in the compartment under the fairing.
    (kerosene and a rag, for a wick.)

    The bike was going 24MPH when I stopped pedaling, and accelerated to 28 MPH.

    It was around midnight, so there weren't many cars on the road, But Then; a blue Oldsmobile pulled out of a parking lot and started chasing me.
    I had to pick up the burning baking pan and drop it in the road. The Olds ran it over and burst into flames.

    Note:
    I used a mixture of 40% aluminum powder in the resin, to make the fiberglass fire resistant.

    Okay , I'll post the picture of the bike again. If you've seen this bike before, please don't complain, some of the readers may not have seen it before:
