I played bike ball, one of the most rare sports in Germany
As a kid and teenager I played bike ball ("Radball" in German), a sport played only by a very small number of people. Maybe more play it today but that time, it meant driving 2 to 3 hours for a tournament. The advantage of a sport with very limited competitors is that it is easier to get into the German championship finals. Even I was able to get in there, despite my limited skills.
