I understand (second hand) that the founder and CEO of FNHon was a former Dahon management team member. FNHon is not the first or last to set up shop building Dahon copies, knockoffs and look-alikes, sometimes using Dahon patented designs without permission or paying royalties.

Dr. David Hon's original mission was to green the earth by putting the maximum number of bottoms on bikes and Dahon the company rarely takes legal action against other bike companies (the Brompton used the Dahon-patented 45º folding handlepost throughout the life of that patent). For this, he's regularly cast as a villain here on Bike Forum - Folding Bikes.

Never seen one in the metal, but reports here and elsewhere on the 'net indicate FNHon bikes seem to be pretty well turned out and now have some innovations of their own.
