How do I find the right vehicle size?
When buying a children's bicycle, take care that your child can touch the ground with the ball of their feet in the lowest saddle position (not just with the tips of their toes), so they have the necessary stability. Base this on the minimum inseam length provided by us beside the bicycle product images.
Determining the inseam length
Place the child (preferably without shoes) upright with their back against a wall and ask it to clamp a book (or similar) firmly between their legs at the crotch. Now you can measure the correct inseam length using a tape measure or measuring ruler between the upper edge of the book and the floor.
