What is Critical Mass?

Critical Mass is a mass bicycle ride that takes place on the last Friday of each month in cities around the world. Everyone is invited! No one is in charge! Bring your bike!

Next San Francisco Critical Mass: December 29th, 2017, 5:30pm, at Justin Herman Plaza (foot of Market Street).

Sep 28: The Sun Will Really Never Set (Milan, IT)

September 7th, 2012 by Russel

Hallo everybody,

Here in Milan we are planning to have a special ride just while you’ll be running your Interstellar ride on Fri September 28th.

This means we will gather at about 2 AM local time (Sat September 29th) and will ride up to about 5 AM in the morning. Then we’ll have breakfast together at dawn right before going to sleep: the sun will really never set that night.

We plan to be a group of about 30 to 50 people, while our ordinary rides gather up to 500 people every Thursday (that’s right: Critical Mass rides in Milan take place weekly).

Maybe some friends of us will be in San Francisco and we’ll try to call them on the phone just before moving from our meeting point at 2:30 AM.

This is just to let you know you won’t be alone: some friends will be pushing their pedals on the other side of the world :-) ))))

Read all about it! Shift Happens: Critical Mass at 20 (excerpts)

September 7th, 2012 by LisaRuth

The 20th Anniversary Critical Mass Ride is 3 weeks away!  And that’s not all — the much-awaited 20th Anniversary book, Shift Happens!: Critical Mass at 20, will be in our hands in a couple weeks! As we count down to 28 September, we want to highlight some of the book’s contributions from the various cities worldwide where the conversation is HOT about Critical Mass.  As the editors, we wanted to know what has changed over the past 20 years, how Critical Mass has altered the landscape for bicycling, bicyclists, bike culture and the urban physical landscape. So, our book has contributions from 31 cities, and we’re gonna try to feature all of them in daily posts excerpting the essays here.

Today we focus on where it all started, here in San Francisco.  Contributors Hugh D’Andrade, Adriana Camarena, Lusi Morhayim, Mario Bruzzone, and Jason Meggs reflect on (respectively) personal transformation, our own limited perceptions of the ride, the move from counter publics to counterspaces, gendered performance within the CM culture, and the benefits and wrong turns of Critical Mass in SF. This selection of SF writers is a good indication of the diversity of style, angle, and topic of the essays in the book. Here is a taste of what you’ll read… Read the rest of this entry »
