portability of a dahon is not bad, but getting the handlebars to fold up properly is slightly tricky, which could be a demerit for trying to fold it up before the bus arrives.
ride quality for dahons are not bad at all. Although you might want to change out the tires for quality 1.75" over the standard dahon 1.5" tires.
there are a few key maintenance points on the dahon, but nothing a home mechanic can't do. Hinges and latches can all be serviced by regular tools.
My only real complaints about dahon are the seatpost setback (not enough in my case) and front wheel (replacing the front can be a hassle).
I can't really say too much about the swift.
