Cycle polo, bicycle polo, or bike polo is similar to traditional polo, except that bicycles are used instead of horses. Invented in Ireland in 1891 by a retired champion cyclist, the sport was initially played on grass, but the hardcourt game was later introduced and gained more interest around the turn of the 21st century. The original owner of this mallet, Irving Arzeta, made the shaft out of a pair of crèches and the head is carved from a cherry tree branch. The grip is a bicycle inner tube taped off at the ends. Arzeta was a Seattle bike messenger and most likely used this mallet in games played in and around Seattle.
