Drivetrain
-
Crankset
The new chainset has a 140 mm crank that is designed for a child's leg length. This 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 recommended tyre pressure is indicated on the side of the tyre (2 to 3.5 bars). 20" inner tube, 1.7" to 2.2" Schrader valve.
