Do you need a helmet to cycle in Denmark?

Not the law on a bike, but a good idea.

Answered at: Checked at:

Short answer

No. In Denmark it is not required by law to wear a helmet on an ordinary bike or on an e-bike that helps up to 25 km/h, for adults or children. A helmet is still strongly recommended, because it lowers the risk of serious head and brain injuries. A helmet is required by law on electric scooters, electric skateboards and similar small vehicles, and on speed pedelecs that help up to 45 km/h. Riding these without a helmet has a fine of 1,500 kr. as of 2025.

Why

  1. No helmet law for bikes and 25 km/h e-bikes.
  2. Helmets are required on e-scooters and speed pedelecs.
  3. No helmet there costs 1,500 kr.

Details

More than half of all cyclists in Danish towns wear a helmet.

Tip

If you rent a city bike or an e-scooter, ask for a helmet; on an e-scooter you need one by law.

What may differ

The speed pedelec rules come from a trial scheme with no end date, so the helmet rules for fast e-bikes can change.

Common misconception

Everyone in Denmark must wear a helmet on a bike.

What actually happens

A helmet is only required by law on e-scooters, similar small electric vehicles and speed pedelecs, not on normal bikes.
