Over a thousand cyclists and other human powered forms of transport congregated for the ride by the NFT on the south side of the river. In stark contrast to our mass, London's Mass has to tolerate the presence of cops on their ride. They attempt to steer the direction of the mass, 'manage' sections of the ride and intervene to 'cork' junctions. These are all things that we collectively perform as a mass ourselves.

The ride took in many of London's tourist attractions including Parliament Square, where riders lapped the square, some sat in the road and defiantly held their bikes above their heads. At Buckingham Palace a stretched limo, a rolls royce and a lamborghini were surrounded by hundreds of riders chanting, "more bikes, less cars!". On the way to Buckingham Palace a cop fell flat on his back - his back wheel had come clean off his bike.

Birmingham's monthly critical mass is this Friday 1st July. We meet up from 5:30 pm at St. Philip's Cathedral in the centre of Birmingham - the ride leaves at 6 pm.
