TECHNICAL INFORMATION

A frame for off-road cycling:

Our engineers designed this aluminum frame. Strong, light and dynamic, it's designed to overcome any obstacle on your mountain bike outings.

Powerful braking :

Brake smoothly and powerfully with front and rear hydraulic disc brakes.

Running-in disc brakes :

Running-in is necessary. On a flat, dry road, perform 3 series of 10 progressive braking operations at increasing speeds.

1) Ride at 15 km/h, brake down to 5 km/h, repeat 10 times.
2) Ride at 20 km/h, brake down to 5 km/h, repeat 10 times.
3) Optional (child's bike): Ride at 25 km/h, brake down to 5 km/h, repeat 10 times.

Between each step, release the brake and ride for a few dozen meters to ventilate the disc. This run-in optimizes pad/disc adhesion.

A 9-speed single-plate transmission:

This bike is equipped with a trigger shifter that can be operated with the thumb and forefinger, for quick shifting through the 9 gears.
The bike is fitted with a 32-tooth single chainring crankset and a 9-speed 11-36 cassette, making it easy to select the gears.
They make it possible to cover the course's gradient with just one control to manage.
You stay focused on riding.

Front suspension to cushion the terrain:

This mountain bike is equipped with an adjustable fork to overcome obstacles (roots, pebbles, stones, etc.) serenely thanks to the 50 mm travel.

A child-friendly saddle:

A saddle with a sporty design, designed by us and adapted to children's morphology. Combined with a sturdy, flexible aluminum seatpost, it provides comfort.

A precise cockpit:

To refine your riding, we've fitted this mountain bike with a short 50mm aluminum stem and 620 mm "Oversize" handlebars. You'll be more precise and livelier when you turn.

Aluminum crankset:

The aluminum crankset has a crank length of 152 mm which is adapted to the child's leg length. This lightweight crankset makes it easier to start pedaling.
The double chain guard prevents chain derailment.

Double-walled rims:

The double-wall aluminum wheels are strong and lightweight.
To make transporting the bike easier, we've fitted the front and rear wheels with a quick-release system.
The wide 24 "x1.95 Skiwall tires are lightweight.
The 24" inner tube is compatible with 1.7 to 2.2 section tires, schrader valve. Inflation pressure is indicated on the tire sidewall (between 2 and 3.5 bar).
