This is an update, since I used to ride my folder to work, but now I ride my steel GT road bike instead. The Los Angeles Metro now has "bike areas" in at least one car per train; plenty of room for a couple of bikes (and their riders) without having to use a folder.

This bike is much more fun to ride, more comfortable and a bit faster. This is not my primary road bike, though I have ridden at least one double century on it.
