Answers to the questions:
1. Can you carry children in this trailer?
2. Can you carry them from birth right through until they can ride on their own or what is the limit age?
3. How many children can you carry in it?
4. Where can you use it, streets/roads, both?
We find the answer in the Reglamento General de Circulacion, article n°12, section 4c.
“It is strictly forbidden to take people in the trailer when you are cycling ON ROADS”.
In the coming months this will modified but until it changes you only can take animals, not persons.
In the cities this rule can be regulated by municipal laws. For this reason you can see this trailer in the parks of some cities (photo n°3), but never on the roads (photo n°4).
