RecumbentWhat IS that thing?! Recumbents may be odd looking, but they have many advantages over a "wedgie" bicycle. Discuss the in's and out's recumbent lifestyle in the recumbent forum.
... these contraptions seem to be popular only among older smokers, some of them must be reaching their natural (or unnatural) expiration date.
I think this contention is valid in at least one respect: They're primarily used by older people, and since they've become so popular, there are a fair number on the used market; and the future market seems assured too. Ex-smokers? maybe around you; but what I see is any older people (mostly guys) who haven't ridden in 50 years and want comfort without having to worry about balance. I have one that I bought used and that's been a work-in-progress for several years. Maybe this year will be the year I put it on the road!
