Why the term ’Critical Mass’ ?

Critical mass is a sociodynamic term to describe the existence of sufficient momentum in a social system such that the momentum becomes self-sustaining and fuels further growth. (Wiki) It seems that the term ’critical mass’ was applied to the cyclist movement following observation of road traffic in China, where in absence of crossing lights the cyclists wait to reach a sufficient number, to be a sufficient mass, to cross the road safely.

A large enough gathering of cyclists naturally imposes itself on the traffic ; participating members don’t have to put up with the traffic’s flow as an isolated cyclist does. By keeping together, cyclists create a car-free zone, which allows them to ride as they like, safely and according to their own rhythm. Furthermore this cyclists’ gathering, rather unusual within the daily traffic, entices the approaching car drivers to slow down. There’s then a reversal of the trend : cyclists reclaim the urban space for the benefit of non-motorised users. The critical threshold is reached !

How does it go?

Flexible and unpredictable, this movement has no real leaders or persons in charge ! Decisions are taken at the same time by nobody and by everybody, on a horizontal basis, without hierarchy, in order to ensure the event runs smoothly.

The itinerary can be prepared ahead, although most of the time it’s improvised on the day, and often very efficiently as cyclists have a far more precise knowledge of the urban space than the average motorist. This year in Paris it will be defined ahead (and the authorities won’t be necessarily informed), and it will be full of surprises!

Everyone is responsible for his/her own safety and for everybody else’s. When approaching a more or less dangerous crossroad, cyclists ensure the procession crosses safely by posting themselves in front of each incoming road, preventing motorists from infiltrating the rally.

Critical mass 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.

Objectives :

It all depends on the individuals who make up the mass. It sometimes doesn’t go beyond a meeting of cyclists and the creation of a new public space ; it can also take a more radical shape in order to bring the attention of the motorists and of the local decision-makers on the difficulties related to the use of bicycle in towns. Its primary aim is absolutely not to ask for more cycling infrastructures but before all to reclaim and occupy what is legitimately ours : the street.
