You say Dahon is "poor function." I bought one for commuting. (If I am too tired, or drunk, or busy to ride home, I fold it up and throw it in a taxi) I find my Dahon Mu XL surprisingly good... The hub gear system is bombproof, the ride is stable and comfortable, and the fit-and-finish comparable to the average Trek MTB or whatever. My experience is that Dahon is quite a nice bike.
