Pneumatic bicycle help

  1. May 2, 2015 #1
    I wish to create a pneumatic bicycle but not sure if i should use high torque low rpm or higher rpm with lower torque.
    I am thinking that a low rpm with high torque will use less compressed air and make better use of the PSI.

    Welcome to PF.

    What exactly is a pneumatic bicycle?
    Does it simply replace the chain with pneumatics?
    Does it operate a compressor / motor to store energy?
    Does it have a fixed volume tank or in an inflatable bladder?

    Have you looked for designs on the web?

    I suspect you will need high internal pressure to get a solid drive.
    If you want efficiency you will need a variable displacement pump / motor.

    Welcome to the PF.

    Pneumatic energy storage is not an efficient mechanism for vehicles. How many such vehicles do you see on the road right now?
