Flagstaff Critical Mass Bike Ride

Critical Mass is an event that began in San Francisco in the early 1990s and has since spread to hundreds of cities around the world. It usually occurs monthly in some places (sometimes weekly) as bicyclists spontaneously come together to ride the ordinarily car-dominated streets of their cities. Critical Mass focuses on the rights of bicyclists and the rights of pedestrians on our own streets.

It is a leaderless ride, free and open to all, where bicyclists take to the streets to promote bicycling as a fun and alternative means of urban transit.

Critical Mass is a bike ride, not an organization, and no two riders participate for exactly the same reason. "What is Critical Mass?" is a question that has as many answers as participants. The only real way to answer the question is to join the ride yourself.

Yes, Critical Mass is essentially a bike party.
