A frame that is suitable for mountain biking.
Our engineers have designed a new aluminium frame. Durable, lightweight and responsive: designed for tackling any obstacles when out mountain biking.
Don't be scared of riding downhill!
Powerful, progressive braking thanks to the front and rear hydraulic disc brakes.
The disc brake acts on the wheel axle to deliver powerful braking under any conditions (dry, wet, muddy, etc.).
Single chainring drivetrain
This bike is equipped with speed controls that are controlled using the thumb and index finger, allowing effortless changes between the 9 speeds. It is easy to shift gears and deal with any kind of hill. With just one control to manage, you can focus on your trajectory.
Front air suspension for cushioning on uneven terrain
This 24" ST 920 bike comes with an air fork that adapts to the child's weight.
Take on new challenging terrain (roots, stones, gravel, etc.) with ease thanks to the travel of the front suspension fork.
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 guard over the chain stops it jumping.
Double-wall rims
The double-walled aluminium rims are light and durable.
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.
