More than just a bike, the Hammacher Schlemmer Velocipede is marketed as the first human powered vehicle with a carbon fiber chasis. At $14,000, you're paying for it, but it's a pretty cool looking ride.
If the picture isn't enough to convince you to buy one, check HS's write-up, which explains, "This is the first human powered vehicle (HPV) to have a carbon fiber monocoque chassis, the same material found in the fastest high-performance Formula 1 automobiles, making it the worlds most advanced three-wheeled velomobile."
See, ti's safe.
The Velocipede was designed by Michael Goretzky, who wanted to make something awesome, as you can tell by his end result.
