About Critical Mass: On the last Friday of September, 1992, a group of San Franciscan cyclists showed up on Market Street for the first ever Critical Mass. This leaderless ride became a monthly “organized coincidence”, and in the years that followed, spread around the world. Celebrating a shared sense of rediscovering urban spaces, Critical Mass riders cross borders and find common cause to have a good time on foot-powered wheels. These uplifting rides also challenge the use of city streets and the domination of cars and oil in our transportation system.
