The event originated in 1992 in San Francisco (typically held on the last Friday of every month); by the end of 2003, the event was being held in over 300 cities around the world.

. It has been described as a "monthly protest by cyclists reclaiming the streets." Participants have insisted that these events should be viewed as "celebrations" and spontaneous gatherings, and not as protests or organized demonstrations. This stance allows Critical Mass to argue a legal position that its events can occur without advance notification of local police. Though they are sometimes described as political, they are not necessarily.


History

Critical Mass-like bicycle tours with hundreds of participants took place in Stockholm, Sweden in the early 1970s. But the first ride within the present wave took place on Friday, September 25, 1992, at 6 pm in San Francisco. At that time, the event was known as ''Commute Clot'' and was composed of a couple of dozen cyclists who had received flyers on Market Street. Shortly after this, some participants in that ride went to a local bicycle shop for a screening of Ted White's documentary ''Return of the Scorcher'', about bicycle culture in the Netherlands and China in comparison with that of the United States. In that film, American human-powered vehicle and pedicab designer George Bliss noted that, in China, both motorists and bicyclists had an "understood" method of negotiating intersections without signals. Traffic would queue up at these intersections until the backlog reached a "critical mass", at which point that mass would move through the intersection. This term from the footage of the movie, was applied to the name of the ride, and the name caught on, replacing "Commute Clot" by the time of the second event.


Organization and tactics

Critical Mass has a decentralized (rather than hierarchical) structure. Critical Mass is sometimes called an "organized coincidence", with no leadership or membership. The routes of some rides are decided spontaneously by whoever is currently at the front of the ride, while others are decided prior to the ride by a popular vote of suggested routes often drawn up on photocopied fliers. The term ''xerocracy'' was coined to describe a process by which the route for a Critical Mass can be decided: anyone who has an opinion makes their own map and distributes it to the cyclists participating in the Mass. Still other rides decide the route by consensus. The disorganized nature of the event allows it to largely escape clampdown by authorities who may view the rides as forms of parades or organized protest. Additionally, the movement is free from the structural costs associated with a centralized, hierarchical organization. In order for the event to function, the only requirement is a sufficient turn-out to create a "critical mass" of riders dense enough to occupy a piece of road to the exclusion of drivers of motorized vehicles. Authorities in New York, California and Oregon have expressed concern with the difficulty of coordinating with the riders, due to the lack of leadership. Critical Mass rides vary greatly in many respects, including frequency and number of participants. For example, many small cities have monthly Critical Mass rides with fewer than twenty riders which offer

, close to Budapest, a Critical Mass Ride has been held every month since 2006 and attracts up to 1,000 or more riders. In the Critical Mass practice of "corking", a rider breaks away from the group to block the side streets of an intersection as the mass crosses. This prevents traffic travelling through the intersection on a green signal and allows the riders to ride through red lights. This both contains cross-traffic while the mass passes and protects the mass from splitting or from drivers who might attempt to pass through the mass.
