ErgoBike Premium 8i

From Germany's Daum Electronics, the Ergo Bike Premium 8i is a stationary bike that's outfitted with speakers, a microphone, monitor, camera, and an internet connection. Think of it as Facebook meets spin class - for a price tag of $3,500.

Users can compete against each other on virtual versions of famous race courses, or even team up for simulated races and talk smack over their headsets.
