Mountain biking has considerably changed the bicycling world in the last years. Sporty wheels, short frames, low saddle heights are typical for this development. Therefore it became a buying criterion of a childrens' bicycle that even the smallest tike should fit onto the biggest bike. Such a bicycle normally does not at all respect childrens' anatomy. The body proportions of a child considerably differ from the ones of an adult. A "zoomed" adults' bike does not make an appropriate childrens' bike.
PUKY goes different ways:
A frame geometry in modern optics with orientation towards trends for adults which ideally respects the specific anatomy of a child. Maximum adjustable range of saddle and handlebar guarantees a long service life, respects the special ergonomic requirements of a child and guarantees a good handling and controllability of the vehicle. The high number of safety features are accepted by children and are easy to handle.
Regarding gear changing:
From approx. 5 years children are stronger and more careful. Normally they are able to control a 3-gear back pedal hub brake. It may sound useful to have more gears but mostly it is confusing and hinders children from learning "slowly-medium-fast" (gears 1-3). Children from 7 years are usually able to use a 7-gear back pedal hub brake or chain gears.
