Case Studies

Every city’s Critical Mass is different. These case studies highlight how rides in different cities started, grew, and adapted to their local context.

Coming soon

We’re collecting stories from Critical Mass communities around the world. Case studies will cover:

• How it started — the origins of the ride in each city
• What worked — tactics and decisions that helped the ride grow
• Challenges — obstacles the community faced and how they overcame them
• Lessons learned — advice for organizers in other cities

Want to contribute?

If you organize or have organized a Critical Mass ride and want to share your city’s story, we’d love to hear from you. Reach out via the project’s GitHub repository.

Cities we’re documenting

• San Francisco, USA — where it all began in 1992
• Berlin, Germany — one of the largest rides in Europe
• Budapest, Hungary — a ride known for massive turnout
• Chicago, USA — a long-running tradition on the lakefront
• São Paulo, Brazil — a major ride in South America
• London, UK — decades of riding through central London

Full case studies coming soon.
