As seen on Adbusters and Rage Against the Machine!

Critical Mass is a monthly bicycle ride to celebrate cycling and to assert cyclists' right to the road. The idea started in San Francisco in September 1992 and quickly spread to cities all over the world. This site attempts to be the most complete guide to all Critical Mass rides around the globe.

Critical Mass has a different flavor from city to city -- there's a big variety in size, respect of traffic laws (or lack thereof), interaction with motorists, and intervention by police. So if you want to know more about Critical Mass, you'll really need to find out what your local ride is like. For those who must know more right now, here's a link to Chicago CM, which I suppose is a "typical" CM ride, if there is such a thing.

Critical Mass has no leaders, and no central organization licenses rides. In every city that has a CM ride, some locals simply picked a date, time, and location for the ride and publicized it, and thus the ride was born.

CM is an idea and an event, not an organization. You can't write to "Critical Mass" -- certainly not by writing to me.

CM is intended to be a celebration, not an opportunity to cause trouble. Those who want to try to tie up traffic as much as possible and be confrontational with motorists are missing the point. We can assert our right to the road without being rude about it. Focus on the ride, not on the cars that also happen to be on the road.

Don't have a CM in your city? Then start one!

Police vs. Critical Mass:
Latest incidents

Winnipeg, MB, Canada. Riders say police used excessive force in arresting five peacful Critical Mass riders. (More: Winnipeg Sun) May 2006

Denver, CO, USA. Police confiscated riders' bikes on the Denver Critical Mass ride. Until the police start impounding people's cars for minor traffic infractions, this is just completely inappropriate -- and an obviously childish exercise of power. (More: Westword) April 2006

Spokane, WA. The police tackled cyclists and arrested almost all of them for "Disorderly Conduct". (more) Dec. 2005

New York. Cyclist victory! The police crackdown on CM for "parading without a permit" has been declared unconstitutional. (more) Jan. 2006

New York. Cyclists filed a lawsuit against NYPD, which has responded with a counterclaim. (more) Oct. 2004

More cases of Police vs. CM
New NYC CM documentary
See a trailer for the documentary about the controversial police crackdown on NYC Critical Mass coinciding with the 2004 Republican National Convention. (Or visit the filmmakers' website.
Good news from Portland
"Exciting things have been happening for Portland's CM. We've had regular meetings with the Portland Police to reach compromises and understanding on some things, and have achieved a ride with less harrassment, more bike officers and fewer in autos / motorcycles, and a much more "feel-good" ride with less tension. This has been largely the result of a few dedicated CM riders willing to go to meetings and print up flyers for riders, etc." -- Brian

Energy & Pollution

The Oil Crisis is coming. Life as we know it is about to change, forever. Believe it. (More: Guardian article, PeakOIl.com, and Life After the Oil Crash)

How much energy we use. Overconsumption of oil means that more people will die as more wars are fought over an increasingly shrinking supply. The U.S. alone uses 46% of all the gasoline used in the world. (more...)

The true cost of gas. Americans whine about the "high" price of gas while not realizing what a sweet deal they're getting.

Pollution by cars causes lung cancer, respiratory problems, urban smog, and acid rain. Greenhouse gases emitted by cars causes global warming, which is not just a concern for the future, it's happening right now. (more...)

The True Costs of Cars

Autos on Welfare. While most motorists think that their gas taxes and registration fees pay for the roads and for other related costs, the truth is that infrastructure is financed mostly by general taxes paid by everyone, which means that those who don't drive are subsidizing those who do.

Societal costs of cars & highways. Our relationship with the automobile causes pollution, noise, congestion, sprawl, big expenses, injury, and even death. The cost is greater than we realize....

The typical American family spends almost $8000 a year to own and operate a car, when you count the car payments, gas, oil, maintenance & repairs, licenses, parking, and insurance.

If you took the money you'd save by getting rid of your car and invested it you could have $2.3 million by the time you retired. (more...)

Art Ludwig shows that AAA underestimates the cost of car use. (more...)

I was born into a cult.

The Aesthetic Realism Foundation is a small psychological cult in New York city. My grandparents were members, so my mother was born into it, and so was I. Recently I created a website about the cult to get the word out. I hope you'll check it out.

We'll cry if you don't link to us.

About this site

There is no such thing as an "official" Critical Mass site. CM is an idea, not an organization. Nobody licenses the individual rides, there are no leaders. This site is just a volunteer effort by a guy who tried to put together a helpful directory of all the rides.

Our links & info are only as good as what people send to us. CM rides often die out or change times, and often nobody bothers to let us know. CM webmasters are also notorious for not updating their pages -- and often don't even list meaningful ride dates, times, and locations -- much less a "last updated" date. We can only print what we know. We're not psychic. So the ride you see listed here might be dead or changed. Sometimes we'll link to a very outdated page or a simple archived email message announcing a ride time if that's all we could dig up for that city. You can help by feeding us corrections & new sites when you know about them.

Finally, here's some hate mail we got.
