About

Critical Mass Derby is a monthly steady-pace cycle ride that aims to gather as many people as possible to ride their bikes together with music on the streets of Derby. It is an independent event that forms part of a decentralised movement to promote cycling as transport and advocate for decent cycling infrastructure.

Beginning in San Francisco 30 years ago, Critical Mass has spread to more than 400 cities with some events amassing over 1000 riders.

Cities with regular Critical Mass events become measurably more cycle-friendly over time. As more people choose to travel by bicycle, the public attitude naturally shifts and reaches a turning point beyond which it is no longer the alternative but the norm — a first-class method of transport.

We believe everybody has the right to cycle from A to B in day-to-day life without feeling intimidated by motor traffic, putting themselves in danger or being regarded as an obstacle or hindrence.

The event aims to:

  • Communicate to the authorities the need for quality cycling infrastructure
  • Demonstrate the importance of cycling and its economical benefits
  • Create safer and more pleasant streets by reclaiming space for people
  • Reduce harmful noise and air pollution from motor traffic
  • Stop the active travel funding cuts
  • Tackle the climate emergency
  • Create opportunities for us to mingle and network with like-minded folk

Safety in numbers

Cycling on some of our roads can be daunting or downright dangerous. Part of what makes Critical Mass so enjoyable is its safety in numbers.

Riding in a large group at a leisurely pace completely changes the way it feels to cycle on the road. The slower pace and sheer number of participants creates an atmosphere where people of all ages and abilities have the confidence to go on two wheels where they otherwise might not.

By flooding the roads as one big unit, we command respect from motorists, taking back control of the streets and making the city safer for all.
