If I only had one bike, it wouldn't be a recumbent. They don't climb well for the average person, they don't jump curbs, they don't fit on bus racks, etc. They are more of a specialized bike, like a good road or mtn bike. Most people have crappy uprights that barely work, I can't imagine using a bent that is in that bad a condition. When you compare the number of bents to other specialized bikes, like downhill or touring or cargo, they aren't that rare.
