I own a few recumbents but my all time favorite bike is my Tour easy.

The bottom bracket being lower than the seat makes it a great bike to learn on, it's just so easy to ride. The center of gravity is nice and low yet you're basically sitting up with an excellent view of your surroundings. Mine is a mix between the SS and the EX model...I'm running a 406 up front, a 700 X 35 in back with 24-42-52 rings and an 11-34 8-sp. cassette.

It's comfortable, it's very stable, and it's plenty fast enough for me. I can easily ride along at 18+mph in the 42 tooth ring with plenty of more speed available without going to the big ring. (not that riding in the big ring is bad...I just find that my speed range in the middle ring meets almost all my needs)
