Monthly in cities around the world, bicyclists take over the streets in an "organized coincidence" called Critical Mass. Riding along several hundred strong, hooting and hollering, whistling, laughing and singing; it is a coup on wheels, a clever tactical strike against our oil-dependent culture.

Containing writings from participants worldwide, this colorful book bundles together 10 years of legendary debates, photographs, artwork, and life-transforming experiences evolving from the celebratory, visionary revolt on bicycles called Critical Mass.
