BTWIN 20 Inch Kids Mountain Bike Rockrider ST 500 6-9 Years Old

This mountain bike is designed for children who are aged 6 to 9 and planning to go biking often. It’s suitable for kids with heights between 120 and 135 cm.For comfortable rides on rough terrain, we’ve equipped this 20″ MTB with a suspension fork. Easily overcome slopes with the 6 speeds.

Frame designed 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.

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 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!

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.

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.

Crankset

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. The crank is covered to prevent the child from coming into contact with the metal part.

The double chain guard prevents the chain from derailing.

Riding position

When mountain biking, it is important to control your path. To make it easier for children to learn, our engineers installed a handlebar and stem that are combined into a single steering block. This eliminates the needs for adjustments, so they can stay focused on the road!

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.

The recommended tyre pressure is indicated on the side of the tyre (2 to 3.5 bars). 20″ inner tube, 1.7″ to 2.2″ Schrader valve.
