Critical Mass Wikia

The Critical Mass Wikia is for information about Critical Mass bike rides in cities around the world.

Critical Mass is a "disorganised coincidence" where a mass of cyclists ride together through the heart of cities. Although the rides have no set route or agenda, its broad aims are the promotion of cycling and sustainable transport and a show of strength in numbers. It is an international phenomenon and has been taking place since 1992. (As of: 17 January 2012)
