It's like polo, with a bicycle. Like with horses on grass, but with bikes and pavement.

A2 Bike Polo on Myspace

Hello we're the local ann arbor polo group.... in fact the only polo group. We normally meet on Sundays at 3pm at Elbel Field, which is at the corner of Hill and S.Division. There is the UM Marching band practice field there that we play on there, it's paved and plenty of room.

Bicycle Polo, Teeter Talk

when someone undertakes to infuse a park with some human hustle and bustle, it's worth mentioning. And cheering for. Here's some photos of this fall's third Bicycle Polo match, which took place at Wheeler Park on Sunday, 28 October at 3pm. Teeter Talk readers will recognize Jimmy Raggett in the first two photos, but perhaps not Matt Churches, who organizes these bicycle polo matches and provides mallets.
