    Ratios

    I would really like to gather some information and hope to find some willing among you.

    Could you supply this ratio for your bike?


    Distance from rear-hub to BB
    -------------------------------------
    Wheelbase (hub to hub)

    On my built-to-order NWT:

    16 13/16"
    ---------
    42 3/4"


    On my Dahon Boardwalk S1

    15 3/4"
    ---------
    41"

    .....and the inevitable question: Why are you doing this???

    Thanks for the info.

    That's approximately 427mm/1086mm for the BF and 400mm/1041mm for the Dahon Boardwalk.

    Why? Just to get a sense of the range and how much deviation from 60/40 there may be in the various folding bike models.

    Flying an airplane is really very simple...Push the stick forward, the house gets big. Pull the stick back, the house gets small. Keep holding the stick back, the house gets big again.

    Thanks for these additional measurements. The CarryMe is almost 50/50!

    size large NWT 2007 (effective top tube 60cm)
    425:1067

    size small NWT 2007 (effective top tube 50cm)
    425:970

    In other words, the rear triangle stays the same throughout the NWT range of sizes.
