A frame that is suitable 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
Brake effectively thanks to the mechanical disc brakes at the front and rear.

SINGLE CHAINRING DRIVETRAIN
This bike is equipped with speed controls that are controlled using the thumb and index finger, allowing effortless changes between the 8 speeds. The single 36-tooth chainring and 11-34 cassette make it easy to shift gears and deal with any kind of hill. With just one control to manage, you can focus on your trajectory.
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. Suntour fork with 50 mm of travel.
Comfort when riding
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
To hone your steering, we have equipped this mountain bike with a short aluminium stem (70mm) and a 540 mm oversize handlebar. This makes you more precise and responsive on turns.
Aluminium chainset
The new aluminium chainset has a 152 mm crank that is suited to the child's leg length. This light chainset allows you to start pedalling more easily.
The double chain guard prevents the chain from derailing.

Double-walled rims and SkinWall tyres
The double-walled aluminium rims are light.
For transporting the bike, we've made it easy to attach/detach the front and rear wheels. They are equipped with a quick-release system.
The tyres use SkinWall technology. This process allows you to reduce their weight, therefore increasing performance, grip and comfort.
