Technical information

Frame designed for mountain biking

We have designed a new aluminium frame for more comfort and less weight. Its pronounced slope, combined with 26" wheels, makes it great for kids from 140 cm to 160 cm tall. This low frame means that budding cyclists can easily get on and off their bike.

Why have 26" wheels?

Go anywhere with less effort! With its bigger wheels, this 26" mountain bike lets young daredevils (1.40-1.60 m tall) take on more demanding terrain. Because the wheels have a bigger diameter, they simply glide over roots and rocks. On downhill tracks, the frame stays more horizontal, making it easier to steer.
Bigger wheels are also more efficient because you travel further with each turn of the pedals!

Changing gears: A SINGLE CHAINRING LIKE THE PROS!

The single chainring is easy and efficient to use:
1 chainring guard and 8 speeds (11-34 MegaRange freewheel). With just 1 trigger on the handlebar, changing gear is child's play. The trigger lets your kids change speed just with 1 fingure.

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 80 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

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.
To hone your steering, we have equipped this mountain bike with a short aluminium stem 45mm and a 540 mm oversize handlebar. This makes you more precise and responsive on turns.
