B'TWIN
We've designed this mountain bike for kids aged 9 to 12 (135 to 150 cm) wishing to improve their MTB skills. Equipped with the same aluminium frame as the 24" ST 900, this mountain bike has an air suspension fork to adjust to the child's weight and hydraulic disc brakes for effective downhill braking

TECHNICAL INFORMATION

A frame that is suitable for mountain biking.

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

Don't be scared of riding downhill!

Powerful, progressive braking thanks to the front and rear hydraulic disc brakes.
The disc brake presses on the wheel axle to produce powerful braking under any conditions (dry, wet, muddy, etc.).

Single chainring

This bike is equipped with speed controls that are controlled using the thumb and index finger, allowing effortless changes between the 9 speeds. The 36-tooth single chainring and 11-36 cassette make it easy to shift gears and deal with any kind of hill. With just one control to manage, you can focus on your trajectory.

Front air suspension for cushioning on uneven terrain

This 24" ST 920 bike comes with an air fork that adapts to the child's weight.
Take on new challenging terrain (roots, stones, gravel, etc.) with ease thanks to the travel of the front suspension fork.

Comfort when riding

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

Riding position

To hone your steering, we have equipped this mountain bike with a short aluminium stem (70mm) and a 540 mm oversize handlebar. This makes you more precise and responsive on turns.

Aluminium chainset

The new aluminium chainset has a 152 mm crank that is suited to the child's leg length. This light chainset allows you to start pedalling more easily.
The double guard over the chain stops it jumping.

Double-wall rims

The double-walled aluminium rims are light and durable.
For transporting the bike, we've made it easy to attach/detach the front and rear wheels. They are equipped with a quick-release system.
24-inch 1.7 to 2.2 cross-section inner tube with Schrader valve. Pressure indicated on the tyre sidewall (between 2 and 3.5 bar).

Bike accessories

This MTB is equipped with a bell, lighting, wheel reflectors and platform pedals.
The frame is also compatible with other B'Twin accessories:
- front and rear mudguards
- stand
- bottle cage
- bag
