Caution: video/sound plays right away. http://www.expresso.com/

My gym has these things. Cute idea, but the "paths" they have bore me. I prefer the video game mode that has you collecting coins and dragons in various colors. The more "expensive" dragons are at the top of steep hills, and the resistance on the bike goes up accordingly.

-- gnat! (I bike for silver dragons? What. Stop looking at me like that.)
