B If the pedal crank arm length of a bicycle increases....

  1. Dec 2, 2016 #1
    You have 2 bikes. They only differ in 1 way.
    The length of the crank arm (where pedal attaches)
    https://en.wikipedia.org/wiki/Crankset

    How will these bikes differ when riding?
    Is one harder to pedal than the other? Why?

    Hi Rip,

    Make an assumption !
    If one crank is twice as long as the other, with which one can you deliver more torque ?
    And with which one you have to press over a longer distance ?
