  1. How can I compare the relative performance of bikes with different
    wheel sizes and gear ratios? I am particularly interested in
    estimating how my existing 21 speed 27" wheel hybrid would compare to
    various 20" wheel 7 speed configurations found in folding bikes and
    some of the new comfort bikes.
