I thought about getting a bent when I firt got back into cycling. Tried a Semi recumbent Giant Revive. Very comfortable and I would still have it if one of my friend's wife hadn't fallen in love with it when she discovered she could ride it without wrist pain. Still even after getting into a better shape and going to a DF road bike I considered a bent as a N+1. I have seen some of them out on the flat moving at least as fast if not faster than I do on a road bike. But hills are another story and I live in a valley. However if I ever get to the point where a DF is too hard for me to ride I am interested in a Cat Trike. After all you would always have your chair with you even on a hill.
