Additional Product Information
Composition
Bike frame : 100.0% Steel
A frame that is suitable 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.
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.
Changing gears (6 speeds)
This bike is equipped with a grip shifter to change between the 6 speeds: It's a safer and easier system for children so they don't need to let go of the handlebar. This makes changing gears to match the terrain simple and easy!
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 potential 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.
Storage instructions
Store the bike in a clean, dry place. Clean and grease the chain regularly. Our tips for before each ride: inflate the tires to the pressure indicated on the sidewall.
Guarantee
for life (frame, stem, handlebars, rigid fork). Find out more about the bike guarantee.
