    Tire Inflation Survey

    We are three high school engineering students attempting to create a new, more efficient solution to inflate bike tires on the go. We would sincerely appreciate it if you would answer all questions to the best of your ability to help with the justification of our proposed problem.
    Thank you!

    Something wrong with the survey. Google returned a "Resource Unavailable" message.

    I'd like to see more solutions with combustibles.

    I've used gasoline in the past and posted about it. It works!

    I'm so sorry the link didn't work. It looked like it was only restricted to people within our high school by default. It should be good to go now with this link

    Thanks again,

    Do the Q's regarding 'portable' refer to on-bike type mini pumps or garage/car floor pumps as well?
    At any rate I did the Q/A assuming you are referring to mini-pumps only.

    If you can balance cost, size, speed, and reliability, you'll be famous. Don't forget about low-pressure, high-volume fatbike tires; and road bikes, which are the opposite.

    Good luck!

    Eatdrinkride, we are talking about mini pumps. We've changed the verbiage to be clearer. Thanks for the feedback!

    Combustibles are too slow, flammables are much quicker.

    Maybe a small pressure vessel combustion chamber that injects fuel-air reaction mass into the tire. Since frames have to be stiff anyway, it could be integrated into the down tube with little weight penalty.

    Actually I'm surprised somebody has not built an air-tank into a downtube, kind of like the pressurized air chamber pumps. Weirder crap has been tried in the past...

    Trapped moisture would be an issue...even more so when continuously repressurized.

    Interesting. The laws of physics dictate the use of a pump. A shock pump makes a poor tire pump, and a tire pump makes a poor shock pump, though they can look very similar to each other.

    I vote we all start using NO2 cartridges instead of CO2, and when we wreck and break ourselves we can just huff the contents of our tubes and kill the pain briefly.

    A pressure vessel that holds a sufficient number of moles would negate the need for a pump to be present.

    Can moles chew through aluminum?

    Yep, gotta use that mole resistant carbon

    Why dont you just make the bottom of the dropper post a pump? If you get a flat, sit on your bike, and pump your seat up and down 100 times, alone in the woods, looking like a pervert. Hahaha. Crack myself up.
