From about 7 years on, it is on average fun and challenging for the children. If you now think: 'But my child is 4 years old and can already ride a bike very well!' Then the following points apply to make a good assessment yourself whether your son or daughter is skilled enough! It is especially important that the child; Can cycle for 1 year without training wheels and is skilled enough to perform pedaling and steering at the same time Can brake in situations where it is necessary, for example for a sharp bend or an emergency stop Has a little bit of experience in the forest, i.e.; has not only cycled at home on the sidewalk or the flat road Not afraid of stones, steps and curves Cycle on an (own) suitable bicycle with pedals and brakes, our smallest children's rental bike starts at 20", which fits approximately for children from 110 cm Does not pose a danger to other cyclists (for example by stopping and dismounting unexpectedly) Accompanied by at least 1 parent on a bicycle (accompaniment on foot is not allowed) Obviously, employees always keep an eye on things and children really don't have to be able to do it perfectly (there is every opportunity to practice!) but a solid foundation is nice to prevent fear and possible accidents.
