I like my Jack
Not really a review - and I don't work for Dahon either. Just bought one after not riding a bicycle since before most posters were probably born 27 years ago, and as in the saying goes, you never forget how to ride. I still suck though, and can guarantee I am NYC's worst rider, but I am working on it.
Anyway, its an ideal, strong bike to absorb the dreadful streets of NY, and its almost completely upgradeable in all aspects. Much recommended, newbies...
