About: Conflicts involving Critical Mass

There have been many conflicts during Critical Mass events since the founding of the worldwide bicycling advocacy event in 1992. The conflicts have resulted in injuries, property damage, and arrests, and both bicyclists and motorized vehicle drivers have been victims. Critics say that Critical Mass, held primarily in large metropolitan cities, is a deliberate attempt to obstruct automotive traffic and disrupt normal city functions, when individuals taking part refuse to obey traffic laws, while participants variously consider it a celebration of cycling, of cyclists' rights, and a practical re-imagining of urban space.
