I had a recumbent. I won't have one again unless I suffer some injury that makes it impossible to sit on regular bike seat. They are very inefficient since you don't have gravity helping on the downstroke. Yes, you can get some good torque by pressing back against the seat, but that's really on good for spinning the rear tire in slick conditions.

A road bike is more efficient than a MTB, but I don't like the riding position anymore. My current ride is a Gary Fisher 29er hardtail. When I ride on road, I put 700x32 street tires on it and lock out the front fork.
