The Danish Transport Authority's Bicycle Order states the following:
Chapter 2: § 3. A bicycle shall not be designed for more than three persons. However, in addition, there may be room for up to four children not older than 7 years, cf. § 25.
Chapter 8: § 25. No more persons may be carried on a bicycle than it is designed to carry. Children not older than 7 years may only be carried on the bicycle when a special seat is provided for them.
Paragraph 2. Special seating for children shall be adapted to the weight and height of the child and shall be shielded from the wheels.
Paragraph 3. Children carried on bicycles shall be securely restrained.
Paragraph 4. The carriage of children shall not prevent the driver of the bicycle from having full control of the bicycle or from giving appropriate signals.
Paragraph 5. The driver of the bicycle must be at least 15 years of age when carrying children on the bicycle.
This means that if the children are under 8 years old, the law allows six children on a cargo bike - if it is equipped for it! So there must be a special space for each of the children and they must be buckled in.
For example, you can use our child bench or child seat with harnesses for the children, or you can attach a car seat or lift for the small child.
The driver of the Christianiacycle keeps the child/children safely in front of him/her on the load, so you can keep an eye on them at all times, and the solid box construction provides good protection for the children.
