Kidical Mass

KIDICAL MASS – Child friendly and
cycle friendly cities

90,000 children, young people, families and friends campaigned for safe streets and independent mobility for children at Kidical Mass on May 14-15 and September 24-25, 2022. At over 400 colorful bicycle demonstrations in small and large cities, people demanded a child-friendly traffic policy. In Barcelona and Cologne alone, 2,000 people each were on the bikes. But the Kidical Mass is not just a big-city phenomenon. In countryside regions such as Amt Schrevenborn 330 participants (19,000 inhabitants), in the north of Germany, or Rösrath 400 participants (28,000 inhabitants), in the mountains, young and old cyclists have also campaigned for a fundamental change.

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.”
