Look for product information, frequently asked questions, opinions...

Question:

Hi. What is the weight of this bike?

Answer:

We do not offer wieght for our kids bikes, but If I had to guess I would say 19-20lbs. Our bikes are typically much lighter than cometitors models.

Question:

When choosing shipped to home, is the bike preassembled? I am mostly worried about fixing the brakes myself

Answer:

The bikes arrive 95% pre-assembled. You should not have to adjust the brakes when the bike arrives.

Top children's mountain bike!

Very solid and nice mountain bike. My son has been riding it for almost three years now and has never had any problems! Now the bike has unfortunately become too small. He wants the same bike again for the next bike, only one size bigger!

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

Lifetime (frame, stem, handlebars). Find out more about this bike's warranty.
