    I'm going to put a jet engine on a bicycle.

    Two and a half years ago I built this bike. And ever since, people will not stop asking me if it's electric, or telling me that I should make it electric. So now just to get everyone to shut up about making it electric, I'm going to put this jet engine on it. It has 36lbs of thrust. The internet will not give me a straight answer as to how much horsepower this equates to, but hopefully it's enough.

    Jets + rockets are measured in thrust. They are generally constant force engines. You get the same acceleration at all speeds!!! 0-100, 100-200, 200-300 all the same. Ok the aero drag increases to offset this.
    The power then depends on the speed, the faster you go the more powerful.

    Internal combustion is best modelled as constant power (assume the average power thru the rev range that the gears allow).
    But this means that acceleration drops as speed increases.

    Assuming you and your bike weighs about 200lbs and ignore aero drag as you speed up, you might achieve 0-60 in like 16s?

    Good luck!

    So I guess you finished your van?

    Is it an electric jet engine?

    No sir, at maximum thrust it consumes 0.6L/min of either Jet A, kerosene, or diesel.

    I looked into the electric jets (ducted fans) but it seems like they would consume way too much electricity to be feasible.

    Yeah the van is basically finished at this point.

    Here's another photo of the engine.

    Dude, why are you SLM? You are too awesome... after this bike experiment, you should try to build a jet pack or something.

    Transform yourself into an Iron Little Man!
