Grand Army Plaza
Critical Mass is a monthly celebration of bicycles and other nonpolluting means of transportation, exercising our right to the road. Critical Mass is a movement, not an organization; no two riders participate for exactly the same reason. Brooklyn Critical Mass started rolling in 2004.
Second Friday of every month, 7:00 p.m., meeting at Grand Army Plaza. Come out and join Critical Mass in Brooklyn. Celebrate cycling, and assert your right to the road — Brooklyn style!
