Kidical Mass

KIDICAL MASS – Child friendly and
cycle friendly cities

40,000 children and their families demonstrated their idea of mobility at the Kidical Mass on 14 & 15 May in more than 200 cities in Germany and 14 other countries.
Kidical Mass is more than just a protest, it gives children a voice, creating a positive vision for the future, connecting the young and old across the cycling community. On 24 & 25 September 2022, there will be the second action weekend in even more cities.

What is it?

Kidical Mass is a worldwide movement. Cyclists from 0 to 99 years old take over the streets to reclaim the road space in colourful bicycle demonstrations. The format focuses on children and sustainable mobility.

For Whom?

Everyone is welcome to join our inclusive events: Small and large cities feel addressed. Old and young. Parents and singles. Cycling initiatives, local groups of large environmental and cycling organisations, private individuals and initiatives.


The vison of Kidical Mass is that all children and young people can safely and independently use cycles as a mode of travel. We demand child-friendly, green places where there are many and varied open spaces for play and social interaction between all generations.

Our demands

Road traffic law

  • Focus on the vulnerability of children and aim for Vision Zero – zero road deaths and serious injuries.
  • Enable children’s independent and safe mobility – on the way to school, to friends, to the sports club or playground.


  • Protected or structurally separated, wide cycle lanes on main roads and country roads as well as protected crossings (based on the Dutch model).
  • 30 km/h speed limit on main roads in town.


  • School streets and traffic-free zones
  • Bicycle lanes and bicycle zones as a comprehensive network and basis for a safe route network to school
  • Roads without through traffic in residential areas (e.g. Kiezblocks Berlin, Superblocks Barcelona) 

Why is the Kidical Mass so important?

„I support the Kidical Mass because I think that cycling with children must be possible without worries. For this, we urgently need a modern, child-friendly road traffic law.“

„It’s time we gave back to children what they have had to do without for decades: to be able to move independently and safely, freely and carefree in their environment. They own the street!“

„We have to make city centres safe for cycling! Cycling not only means mobility, but is also important for child development – and independently mobile children protect our climate at the same time. That’s why I support the Kidical Mass.“
