Big Wheel

Ride inside a seven-foot-high unicycle

Can't let go of the Olympics? While it's unlikely you'll be able to purchase 2008 Chinese drummers to play at your next barbecue, apparently the big human-powered wheel from the closing ceremonies can be yours for the bargain price of $1690.

The Monovelo claims to be the first commercially available human-powered monowheel. Built from ASB plastic combined with a steel frame and a rubber tire, the contraption measures just under seven feet in diameter and weighs in at 84 pounds. The device claims a maximum payload of 220 pounds, so lay off the burgers.

Monovelo claims it could be a great advertising tool and is even street legal in most countries. With a top speed of 12.5 miles per hour, that's a lot of good exposure time.
