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

Could you supply this ratio for your bike?

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.

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.
