Critical Mass London: last friday of the month South Bank by National Theatre, 6.30pm

My flatmate has bought a single speed after not riding a bike since he was a little kid. He's mainly doing laps of the park at the moment, but I'm going to try and drag him along for the May version of this, for his first ride.
Hopefully I would of met you before then on the Lea river ride. Its always good to put faces to names.
