The correct geometry of the bicycle is like a nice piece of garment – in order to be favorite and comfortable, it must have been made by a very good specialist, of quality material and be in the right size for you. All sizes (geometries) in this respect are in compliance with the kid’s body, so as to ensure proper posture when pedaling. In this way we provide the best balance between the correct seat height and the ability of the kid to step on the ground.
