Components
Parts found in a manufacturer catalog show their brand, model and key numbers, and the steps show how precisely they are identified: brand, series, model, or the exact product. The info button has every detail and the text the manufacturer published.
Suspension
-
Fork
Take on new challenging terrain (roots, stones, gravel, etc.) with ease thanks to the travel of the front suspension fork.
Drivetrain
-
Crankset
The new aluminium chainset has a 140 mm crank that is designed for a child's leg length. This lightweight chainset allows you to start pedalling more easily. The double chain guard prevents the chain from derailing.
Brakes
-
Brakes
Because children have smaller hands than adults, it's not always easy for them to reach the brake lever. This is why our engineers designed a brake lever that is closer to the handlebars and thus easier to hold.
Wheels and tires
-
Tires
The tyres are designed for mountain biking. The lateral lugs provide good grip on turns. The tyres use SkinWall technology. This process makes it possible to reduce their weight, provide greater flexibility, therefore increasing their performance, grip and comfort. The recommended tyre pressure is displayed on the tyre sidewall (between 2 and 3.5 bar). 20-inch 1.7"-2.2" wide inner tube with Schrader valve.
