Design details
Frame designed for mountain biking.
Our engineers have designed a new aluminium frame. Lightweight and responsive: designed for tackling any obstacles when out mountain biking.
CONTROLLED BRAKING
Effective braking thanks to the cable-activated disc brake at the front and a V-brake at the rear.
The disc brake acts on the wheel axle to deliver powerful braking under any conditions (dry, wet, muddy, etc.).
The V-brake is composed of 2 levers equipped with pads that exercise more or less pressure on the rim to slow or stop the rotation of the wheels.
Front suspension to cushion unpredictable terrain
Take on new challenging terrain (roots, stones, gravel, etc.) with ease thanks to the travel of the front suspension fork.
Changing gears (6 speeds)
This bike is equipped with a grip shifter to change between the 6 speeds: a safer and easier system because the child doesn't have to let go of the handlebar.
This makes changing gears to match the terrain simple and easy!
Why have we created a brake lever specifically for children?
Because kids 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.
A reinforced, ergonomic saddle
A saddle with a sporty design, designed with care to adapt to the morphology of children. Combined with an aluminium seat post (sturdy and flexible) for even greater comfort.
Riding position
We equipped this mountain bike with a short aluminium stem (60 mm handlebar) and an oversized 520 mm handle for more controlled steering. This makes you more precise and responsive on turns.
Aluminium chainset
The new aluminium chainset has a 140 mm crank that is designed for a child's leg length. This light chainset allows you to start pedalling more easily.
The double chain guard prevents the chain from derailing.
20" wheels and MTB SkinWall tyres
The tyres are designed for mountain biking. The side lugs provide good traction for cornering.
The tyres use SkinWall technology. This process reduces their weight and makes them more flexible, which increases 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.
