Critical Mass is a global movement of cyclists riding together to celebrate bikes, reclaim streets, and build community. This platform helps you find a ride, start a ride, and keep it going.
Critical Mass is a monthly bike ride that happens in hundreds of cities worldwide. There's no organization, no registration, no fee. Riders meet at a set time and place and ride together through the streets. It started in San Francisco in 1992 and has since spread to every continent.
