Might as well -- or even better, I'd say -- just buy a FnHon frameset and build the bike yourself,
if you have access to the Asian market. For the same money, perhaps even less, you'll end up with a bike with much better components and with the exact parts want. 100/135mm OLD on these quality
FnHon Zephyr disc framesets that sell for under $150 (handlepost included).
Or a Litepro Eno disc frameset which sell for under $120 (handlepost included). 100/135mm OLD too.
Something like this FnHon Gust 16" can be built with much better parts and components than a Dahon K3 Plus for
under $600.
As I've said before, these complete Dahon bikes have long become uncompetitive in the face of all manner (steel or aluminium alloy, rim or disc brake) of good, affordable Litepro and FnHon framesets. And you need not build them yourself. Tell a shop what your want and they'll build it for you.
