Rockrider ST 100 Kids' 24-Inch 9-12 Years Mountain Bike - White

A frame that is suitable for mountain biking

Our engineers have designed a new, robust steel frame. The frame's rear chainstays are short, making the bike responsive and easy to handle.

Controlled braking

Two V-Brake pads for effective braking.

These brakes are composed of callipers that exert more or less pressure on the rim to slow or stop the rotation of the wheels.

Changing gear

This bike is equipped with a grip shifter to change between the 6 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!

A reinforced, ergonomic saddle

A saddle with a sporty design, designed with care to adapt to the morphology of children. It is equipped with a plastic section on the rear (a bumper) to protect against any impacts.

Riding position

To provide you with maximum comfort, this mountain bike is equipped with a high-rise stem. Your position on the bike is slightly raised so you can better anticipate your trajectory.

Crankset

The new chainset has a 152 mm crank that is adapted to the length of your child's leg. This chainset allows you to start pedalling more easily.

The double chain guard prevents the chain from derailing.

24" wheels and MTB 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 tyres are designed for mountain biking. The lateral lugs provide good grip on turns.

The recommended tyre pressure is indicated on the side of the tyre (2 to 3.5 bars). 24" inner tube, 1.7" to 2.2" Schrader valve.

This MTB is equipped with a bell, lighting, wheel reflectors and platform pedals.
