what's to explain? you are on a bike, mallets made out of ski poles, two goals on each end, teams of three players. it's like polo on a horse, but on a bicycle. you use a roller hockey ball on hardcourts, softer ball on grass courts, and you try to score on the other side. each game is played to five points. its really fun, you should try it sometime.
