I'd like to test ride that Nyfti. It seems to have a relatively long wheelbase, which I like, yet the fold looks fairly small. I also can appreciate the thought put into the frame rod supporting the main hinge, the addition of roller wheels to allow the bike to be rolled around while folded and the addition of a rear rack... although the linkage/strut used to tame the serpentine chain while folded looks "interesting".

In short it looks like an honest attempt to design a folding bike for the utilitarian/commuting cyclist.
