1994 saw jungle music move from the underground into mainstream consciousness, the hated Criminal Justice Act was passed at the end of the year, and the Tories were clinging on to power after a disastrous 14 years in government, hollowing out public services and destroying the social fabric of the country. And Critical Mass London had its genesis on the 15th of April 1994, as the CHARM ride, occupying space around dangerous roundabouts in central London. It then morphed into the Critical Mass ride, mirroring the "last Friday of the month" occurrence from cities in the US.

It has been through thick and thin, had its highs and lows, been subject to harassment and surveillance, mass arrests and prosecutions, and legal attempts to shut it down. But still it endures, every month without fail, an unbroken line for three decades. It celebrates the diversity of cycling in this city, to temporarily re-occupy our city streets which have been near monopolised by hyper-capitalist car fetishism. It is a living, breathing example of an anti-authoritarian, non-hierarchical event that has seen so many other movements and organisations come and go.


And what better way to celebrate THIRTY YEARS of this than a huge coming together of all participants, past and present, young and old, all genders, all colours.


Let's celebrate this milestone! This birthday meetup will allow us to ride, laugh and dance together, to reminisce about the past, and think about the future.


If you have friends who used to come, please let them know! If you know other riders who've never been before, invite them! If you are still connected to networks from the past, please spread the word! If you have any ideas that you think will make this party even better, then just do it!

Q: Why not have it on Monday 15th (the exact 30 year anniversary), or Friday 26th April? Many riders have left the city over the years, or find it difficult to come out at night with caring responsibilities, or just with age! People from other CMs across the UK have also indicated their interest to visit. A Sunday afternoon ride allows more people to travel to London, and makes meeting up far easier. It also facilitates us all staying together for a party afterwards! But if you want to organise another birthday party ride, on either or both of those other evenings, please do!


More information will follow over the coming weeks!
