Additional Product Information
Composition
Frame (for bike): 100.0% Steel
A frame that is suitable for mountain biking
Our engineers have designed a new, robust steel frame. The frame's rear chainstays are short to make the bike dynamic and easy to handle.
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 between the 6speeds
This bike is equipped with grip shifter to make it easy to change between the 6 speeds - more precise control over your pedalling.
Controlled braking
Two V-Brake pads for effective braking.These brakes are composed of callipers that exert more or less pressure on the rim to slow or stop the rotation of the wheels.
A reinforced, ergonomic saddle
A saddle with a sporty design, designed with care to adapt to the morphology of children. It is equipped with a plastic cover at the back (a bumper) to protect against any impacts.
Riding position
To provide you with maximum comfort, this mountain bike is equipped with a high-rise stem. Your position on the bike is slightly raised so you can better anticipate your trajectory.
Crankset
The new chainset has a 152 mm crank that is adapted to the length of your child's leg. This chainset allows you to start pedalling more easily. The crank is covered with a guard to stop you coming into contact with the metal part.The double guard over the chain stops it jumping.
24” wheels and skinwall mtb tyres
To transport the bike, we’ve made it easy to remove and attach the front wheel. It is equipped with a quick-release system.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).24-inch 1.7 to 2.2 cross-section inner tube with Schrader valve.
