Can you take a child in a bike trailer in Denmark?
Two seats, belts and a weight limit.
Short answer
Yes. A bike trailer or sidecar may be used to carry up to two people, and each must have their own seat with guards against the wheels. The people in the trailer must be properly strapped in, and the rider must be at least 15 years old. The total weight of the trailer may not be more than 60 kg, or 100 kg if it has an overrun brake. The trailer may be at most 1 metre wide, and the bike and trailer together at most 3.5 metres long.
Why
- Up to two people in a trailer.
- Everyone in it must be strapped in.
- Total weight up to 60 kg, or 100 kg with a brake.
Details
A trailer must have its own red rear light when you ride in the lighting-up period.
Tip
Weigh the trailer with the children in it once, so you know you are under the 60 kg limit.
What may differ
A trailer bike with its own saddle, handlebar and pedals is the one exception: the child on it does not need a belt.
Common misconception
There are no rules for bike trailers in Denmark, any trailer will do.
What actually happens
Trailers have rules on seats, belts, width, length, weight and a rear light.
