ok lets start with this tidbit of info ....
Curve D3 is currently not available from Dahon, some dealers might have old stock, but the warehouse is empty .... that doesn't mean that they will be back any time, just right now ... no luck
Eezz is available same as Jifo in ONE speed only at least in the USA
the 3 speed model is neither in stock, nor is there any price for it ... maybe in 2017 ?
One thing which drives me nuts as a dealer is that the Dahon website is mostly International, whatever that means, but you really have to look for the USA website, and even there are model variations which do not exist...
