Germany has no mandatory helmet law, meaning that children here are not required to wear a helmet in the Croozer – neither as a bike trailer, nor as a jogger. Nevertheless, we recommend helping children get used to wearing a bicycle helmet as early as possible. There are even special “passenger helmets” with flat backs for use with bike seats and trailers (e.g. the Abus model “Rookie”). But this is only relevant for “older children”. It is not possible for infants in the Croozer Baby Seat to wear a helmet: It would be too difficult for them to rest their head safely and comfortably against the flat surface of the Baby Seat. Therefore, children should not start wearing a bicycle helmet in the Croozer until they are old enough to sit upright unassisted.
If you are planning to use the Croozer outside of Germany, be sure to read up on the laws that apply in the state or country that you live in or will be visiting: If there is a mandatory helmet law, then your child – and of course you as the cyclist – will have to wear a helmet at all times.
