An ideal setting for mountain biking.
Our engineers have designed a new aluminum frame. Strong, light and dynamic, it's perfect for overcoming any obstacle on your mountain bike outings.
Don't be afraid of descents!
Brake progressively and powerfully with front and rear hydraulic disc brakes.
The disc brake acts on the wheel axle to deliver powerful braking in all conditions (dry, wet, muddy...).
Single-plate transmission
This bike is equipped with a thumb-and-index shifter for quick shifting through all 9 gears. The 36-tooth single chainring and 11-36 cassette make shifting gears a breeze, and allow you to cover routes with uneven terrain. With just one control to manage, you can stay focused on your trajectory.
AIR front suspension to cushion the terrain
This 24" ST 920 is equipped with an air fork, easily adaptable to the child's weight.
Face new obstacles (roots, pebbles, stones, etc.) in complete serenity thanks to the front fork's travel.
Steering comfort
A saddle with a sporty design, designed by us to adapt to children's morphology. Combined with a strong, flexible aluminum seatpost, it provides even greater comfort.
Pilot station
To refine your riding, we've fitted this mountain bike with a short (70mm) aluminium stem and 540 mm long "Oversize" handlebars. This means you'll be more precise and livelier in your turns.
Aluminum crankset
The new 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-wall rims
The double-walled aluminum wheels are strong and lightweight.
For transporting the bike, we've made it easy to assemble and disassemble the front and rear wheels. They are equipped with a quick-release system.
24" inner tube, section 1.7 to 2.2, schrader valve. Pressure indicated on tire sidewall (between 2 and 3.5 bar).
Bicycle equipment
This mountain bike is equipped with a bell, lights, wheel reflectors (reflectors) and flat pedals.
The frame is also compatible with other B'TWIN accessories:
- front and rear mudguards
- kickstand
