Additional Product Information
Composition
Bike frame : 100.0% Steel
Frame designed for mountain biking
Our engineers have designed a new sturdy steel frame. The frame's rear chainstays are short, making the bike responsive 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 gear
This bike is equipped with a grip shifter to change between the 6 speeds: It's safer and easier for children as they don't need to let go of the handlebar to change gears. This makes changing gears to match the terrain simple and easy!
Controlled braking
2 V-Brake pads for effective braking.These brakes are composed of calipers 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 from any impact.
Storage instructions
Store the bike in a clean, dry place. Clean and grease the chain regularly. Our advice for before each ride: inflate the tires to the pressure indicated on the sidewall.
Guarantee
