Super Light Bicycle

Lighter than carbon fiber.

Here's an example of new technology that is much lighter than carbon fiber.  These new bikes are filled with air and are collapsible to fit inside your pocket.  Each time you deflate it however, it does take a bit of time to re-build it.  If you happen to know a performing Clown, you may also have your Balloon Bike Mechanic.  Now riding them is a whole other story.  While lighter than carbon fiber, these Balloon Bikes basically have zero strength.  If you should try and sit on one, you would just fall to the ground thus making riding it impossible.  Visit Circle City Bicycles and get the real deal on light and functional bikes.
