Technical information

Frame designed for mountain biking

Our engineers have designed a new aluminium frame. Durable, lightweight and responsive: designed for tackling any obstacles when out mountain biking.

Controlled braking

Effective braking thanks to the cable-activated disc brake at the front and rear.
The disc brake acts on the wheel axle to deliver powerful braking under any conditions (dry, wet, muddy, etc.).

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 easy triger to change between the 7 speeds:
an easier, safer system as the child's hands stay on the handlebars.
This makes changing gears to match the terrain simple and easy!

Why have we created a brake lever specifically for children?

Because children have smaller hands than adults, it's not always easy for them to reach the brake lever. This is why our engineers designed a brake lever that is closer to the handlebars and thus easier to hold.

A reinforced, ergonomic saddle

A saddle with a sporty design, designed with care to adapt to the morphology of children. Combined with an aluminium seat post for even greater comfort.

Riding position

We equipped this mountain bike with a short aluminium stem 45mm and an oversized 520 mm handle for more controlled steering. This makes you more precise and responsive on turns.

Aluminium chainset

The new aluminium chainset has a 140 mm crank that is designed for a child's leg length. This light chainset allows you to start pedalling more easily.
The double chain guard prevents the chain from derailing.

20" wheels and MTB SkinWall tyres

The tyres are designed for mountain biking. The lateral lugs provide good grip on turns. The tyres use SkinWall technology. This process reduces their weight and makes them more flexible, which increases performance, grip and comfort.
20-inch 1.95 tyre

Bike accessories

The frame is also compatible with other B'Twin accessories:
- front and rear mudguards
