This fast past game takes from its original horse version.
The only true difference of Bicycle Polo and traditional Polo is the fact that the game is played on a bicycle than a horse. The field size is also different due to what is being ridden. The ball equipment, on the other hand, is similar to that of a traditional polo ball.
The arena polo ball will be used. The ball shall be not less than 12.5″ or more than 15″ in circumference and not less than 170 grams or more than 182 grams in weight. In a bounce test from 9′ on concrete at 70ºF, the rebound should be a minimum of 54″ and a maximum of 64″ at the inflation rate specified by the manufacturer.
