Cyclobol It is a sport that takes place on bicycles on a hard ground court similar to futsal. It is practiced on special fixed-gear bicycles with particular geometry, seat almost behind the rear wheel and can be pedaled back and forth. Cyclobol is very popular in Germany, Switzerland, Austria, Belgium, Czech Republic and Japan. The International Cycling Union is the one who regulates this sport under the term "Indoor Cycling" and, like the other disciplines governed by the UCI, the world champions wear the Arco-Iri Jersey.
It was created in 1893 by a German-American, Nicholas Edward Kaufmann and the first world championships were held in 1929. The Czechoslovak brothers Jindřich and Jan Pospíšil won the majority of the world championships with twenty victories between 1965 and 1988.
