A lightweight frame for committed mountain biking:

Our engineers designed this aluminium frame to make this a lightweight bike, under 10 kg. Very sloping for better handling on challenging terrain. There are also 2 inserts on the frame so that you can attach a bottle cage for longer rides.

A rigid fork is a choice:

There is no suspension fork on this 20" EXPL 900 model. The goal is to save weight without compromising on shock absorption. To keep a suspension effect, we used a new pair of tyres with a wide cross-section of 2.2. Cushioning and traction guaranteed.

A 8-speed drive train designed for kids:

This bike is equipped with our innovative Easytrigger shifter, designed to make it easy to shift between the 8 speeds. The derailleur allows you to switch gears on the 11/34 freewheel. The 32-tooth chainset has 140 mm cranks and is equipped with a double chainguard to prevent derailment.

Controlled braking:

We have equipped the bike with front and rear mechanical disc brakes for progressive, powerful braking. The discs are 160 mm.

Breaking in disc brakes:

A bedding-in process is required. On a flat, dry road, perform 3 sets of 10 progressive brake applications at increasing speeds. 1) Ride at 15 km/h, brake down to 5 km/h, and repeat 10 times. 2) Ride at 20 km/h, brake down to 5 km/h, and repeat 10 times.3) Optional (kid's bike): Ride at 25 km/h, brake down to 5 km/h, and repeat 10 times.Between each step, release and ride for a few dozen metres in order to ventilate the disc.This bedding-in process optimises the pad/disc adhesion.

A comfortable cycling position:

The 580 mm oversize handlebars provide stability on descents, good balance when standing, and improved handling. This handlebar width also allows for better chest opening to optimise breathing.

A chainset with cranks adapted to children:

The new chainset has a 140 mm crank that is designed for a child's leg length. This chainset allows you to start pedalling more easily.

20" wheels and all-terrain tyres:

To transport the bike, we’ve made it easy to remove and attach the front wheel. It is equipped with a quick-release system. The 20" lugged tyres with a 2.2 cross-section provide traction and lots of comfort. They help compensate for the lack of a suspension fork. The recommended tyre pressure is displayed on the tyre sidewall (between 2 and 3.5 bar). The 20" inner tube is compatible with cross-sections of 1.7 to 2.2. It has a Schrader valve.
