Thanks guys! I think the general consensus is the EX is a gorgeous bike but probably priced a few hundred the wrong way. However if they sell all 250 allocated in the limited edition in this country, I guess it fulfils its purpose for Dahon. It has expensive and very high grade components but I'd have thought around £1700-1800 was more realistic!
I don't think I could let go of my Brompton really but this is the closest to temptation I've been. If I had the money I'd buy it even at £2100 as it's so unusual, never mind the spec. Dahon do make some absolutely gorgeous and capable bikes at the top end.
