Time Out says
This wacky one-wheeled weekend rolls into town and begins with a pitstop in Battery Park (10 am on Aug 29), followed by a ride over the Brooklyn Bridge and ending with a stage show at Coney Island (Aug 30, meet at 2pm in front of City Hall in Manhattan on the base of the Brooklyn Bridge). Don't miss the main event—a giant festival on Governors Island with races, competitions, exhibitions, unicycle sports (basketball, hockey and sumo on wheels!), music, live performances and more one-wheeled activities for the whole family (Aug 31 and Sept 1 from noon–5pm). Learn more about the lineup on the festival's website. All ages.
