- ADJUSTABLE CHILDREN’S BRAKE LEVERS
Lightweight aluminium children’s brake levers with adjustable reach are designed to suit a child’s grip. - CHILD ERGONOMICS
Optimised ergonomics for a child’s body are the result of our many years of experience with children’s needs. A shortened overall frame length, lower step-over and higher handlebars make riding more confident and feel more natural and safer for the child. - BELT INSTEAD OF CHAIN
Using a belt instead of a chain has many advantages. It is maintenance-free and does not need lubrication. The rubber belt is safer than a chain and sprockets. It is also lighter and quieter. - INTERNAL GEAR HUB
Simple, fast and child-friendly shifting with an internal gear hub brings a number of advantages. Compared to classic derailleurs it is more compact. Easier shifting thanks to gears in constant mesh. Longer service life than gears in a classic gearbox. Easy to achieve a wide gear range relative to its size. - DESIGNED IN BRNO
Designed and developed in Brno in cooperation with a leading retailer of lightweight children’s bikes, based on observing the first pedal strokes of thousands of children in specialist children’s cycling stores. - LIGHTWEIGHT ALU FRAME
The 7.9 kg weight combined with an optimal children’s gear ratio is a key bike parameter for easy learning and riding. - NARROW FRONT FORK
Thanks to the lightweight, narrowed front fork with a 75 mm hub, the bike is easier to steer into corners.

BASIC DIMENSIONS OF THE RASCAL 20" BIKE

Also worth mentioning is the unique transparent tinted lacquer finish, which lets the details and exclusivity of the precision-welded brushed aluminium frames made from high-strength lightweight 6061 aluminium alloy stand out. This paint finish gives the wheels the unmistakable character of pure materials. Each wheel is an original in its own way thanks to the hand-applied transparent paint.
