            Description

            6 to 9-year olds (120 to 135 cm) wanting to start mountain biking.

            Frame designed for mountain biking

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

            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.

            Changing gears (6 speeds)

            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 cover at the back (a bumper) to protect from any impacts.

            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!

            Crankset

            The 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.

            20" WHEELS AND MTB TYRES

            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). 20" inner tube, 1.7" to 2.2" Schrader valve.

            MTB fittings

            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 - saddle bag - stabilisers: https://www.decathlon.co.uk/20-and-24-stabilisers-id_8550741.html
