In the closing ceremonies of the Olympics, how were the bicycles with the big lighted wheels constructed?

Question

I could tell that there was a wheel within a wheel, but I couldn't figure out how it was connected to the pedals and stay stable. The big wheel didn't seem to have an axle.

Answer 1

I can totally answer this... Since I built them myself.

Answer 2

I read the lights came from monkeylectic, first link.  The type of bike is called a monocyle - / monowheel (second link)

Answer 3

The exact same mono-wheel you can get if you just write to me.

Soon (about mid of September 2008) there will be a website, where you can get more information about the mono-wheel, it will be www.monovelo.com
