If you like the idea of exercise through cycling, but also enjoy the camaraderie of riding with others, here's a product for you. The Ergo Bike Premium 8i is an exercise bike that keeps you inside away from dangers such as fresh air all while providing you some companionship while you ride.

It does this by letting you talk to fellow riders via VoIP, ride on "virtual courses," and keeping you up to speed on your heart rate as well as those of your buddies. Sure, at $3,500 it'd be a lot cheaper to buy a real bike and go riding with real friends, but if you're in a place with lousy weather or you have no friends, I guess this is better than nothing. — Adam Frucci
