We've fitted this 24-inch mountain bike with a suspension fork and V-brakes. Thanks to its 18 gears, you can tackle hilly trails with ease and enjoy the terrain!

TECHNICAL INFORMATION

A setting suited to mountain biking

Our engineers have designed a robust new steel frame. The rear chainstays are short to make the bike dynamic and easy to handle.

Front suspension to cushion the terrain

Tackle new obstacles (roots, stones, rocks, etc.) with complete peace of mind, thanks to the front fork's long travel.

Changing the 18 speeds

This bike is equipped with 2 twist grips for easy shifting of the 18 gears.
Left (chainrings): you manage the upshift/downshift.
Right (gears): you adapt your effort more precisely.

Master braking

Brake efficiently with 2 V-Brake brake pads.
These brakes consist of 2 calipers fitted with brake pads that apply varying degrees of pressure to the rim to slow or stop wheel rotation.

An ergonomic, reinforced saddle

A saddle with a sporty design, designed by us to adapt to children's morphology. It features a plastic shell at the rear (bumper) to protect it from impact.

Pilot station

For maximum comfort, this mountain bike is equipped with an inclined stem. Your position on the bike is slightly raised, so you can better anticipate your trajectories.

Crankset

The new crankset has a crank length of 152 mm which is adapted to the child's leg length. This crankset makes it easier to start pedaling. The crank is covered with a protective cover to prevent you from coming into contact with the metal part.

24" wheels and SkinWall MTB tires

For transporting the bike, we've made it easy to mount/dismount the front wheel. It features a quick-release system.

The tires use SkinWall technology. This process reduces their weight and provides greater flexibility, thus improving performance, grip and comfort.
Recommended tire pressure is indicated on the tire sidewall (between 2 and 3.5 bar).

24-inch inner tube section 1.7 to 2.2, schrader valve.
