Celebrating 32 years of Critical Mass London.
 
Always free, fun and easy. Reclaiming urban space for hundreds of cyclists, with music and general good-natured chaos.
Meet up on the south bank under Waterloo Bridge at 7pm. Ride usually leaves approximately 7:30pm. Just show up on a bike (or roller skates, skateboard, etc.), no booking or ticket required.

The London Mass meets at 7:00pm, on the last Friday of every month on the South Bank under Waterloo Bridge, by the British Film Institute.
 
WHAT’S IS ALL ABOUT?
Critical Mass is often described as an ‘unorganised coincidence’. It happens when a lot of cyclists happen to be in the same place at the same time and decide to cycle the same way together for a while.
WHAT’S THE PURPOSE?
“Everyday, all over the world, people are resisting the problem culture of the car by getting on their bikes and riding, instead of driving.
Critical Mass is a celebration of the alternatives to cars, pollution, accidents and the loss of public spaces and freedoms.
Not an organisation or group, but an idea or tactic, Critical Mass allows people to reclaim cities with their bikes, just by getting together and out-numbering the cars on the road”
WHAT HAPPENS ON A CRITICAL MASS?
Each one is different and they follow no set route, with the direction being spontaneously chosen as people cycle along. Anyone is free to join or leave the ride as it pedals along.
The ride lasts no more than a couple of hours (depending on the weather!) and usually ends in a conveniently placed pub (or squat) for more drinks.
Most all, they are peaceful, safe and fun!
DO I NEED A BIKE?
Nope! Critical Mass is not just for bikes – skateboards, roller blades, wheelchairs, pogo sticks – in fact any form of non-motorised, non-polluting transport are all very welcome!
