  • Critical Mass is NOT a race.
  • The CM movement aims to raise awareness about the viability of bicycles as a form of transport; the cyclist's right to share public space safely and the need for cycling infrastructure. Critical Mass Joburg aims to bring more people back into the city. CM is about having fun, in a group, on wheels.
  • CM makes an impact because it is a group. The group moves slowly and must not be separated. When the mass moves through a traffic light, the mass must stay together, even when the light changes, or it is dangerous. If cars get caught in the mass, allow them space to exit to the right. Always try to keep a lane open to the right of the mass for cars to pass safely by
  • For CM to be safe and fun, we need to abide by some consensual rules:
  • Answers to FAQs
  • There is parking on the street at the start, or in a public lot on Juta 1 block from the start, for R20,00
  • The route changes, but is around 20kms and as easy as a Jozi route can be.
  • The ride is free
  • All you need is you and your bicycle - please make sure your bicycle works and that you have basic spares
  • This ride is unofficial. There are no marshals, support or sweep vehicles, no medical support on the scene. We recommend that you ALWAYS ride with friends
  • We will post the route before the ride. Any questions about the route, and where we ride, please see the website
