Description

We have designed this mountain bike for children aged 6 to 9 (from 120 to 135 cm) who want to get started with mountain biking. Frame adapted for riding Our engineers have designed a robust steel frame. The rear chainstays of the frame are short to make the bike dynamic and easy to handle. Why have we created a brake lever adapted to children's hands? Since children's hands are smaller than those of adults, it is not easy for them to grip the brake lever. Therefore, our engineers and designers have devised a shape closer to the handlebar, which is easier to grip for braking. 6-speed gear shifting Bike equipped with a twist grip to shift the 6 speeds: an easier and safer system, as the child does not let go of the handlebar. Changing gear to adapt to the terrain becomes a simple task! Braking control Effective braking thanks to the 2 V-Brake type caliper brakes. 2-caliper brakes with pads that exert more or less pressure on the rim to slow down or stop the wheel rotation. Ergonomic and reinforced saddle We have designed a saddle with a sporty design, to adapt it to the physical constitution of children. It features a plastic frame at the back (bumper) to protect it from potential impacts. Cockpit In mountain biking, it is important to master the trajectory. To facilitate learning, our engineers have mounted a one-piece handlebar that merges with the stem. No adjustments, so they can stay focused on the trail! Bottom bracket The length of the bottom bracket crank is 140 mm, adapted to the length of children's legs. This bottom bracket allows pedalling to be started more easily. The crank is covered by a guard so that the child is not in contact with the metal part. The double chain guard prevents the chain from coming off. 20" wheels and MTB tyres Tyres adapted for mountain biking practice. The side knobs provide good grip in corners. The recommended tyre pressure is indicated on the tyre sidewall (between 2 and 3.5 bar) 20-inch inner tube with a section between 1.7 and 2.2. Schrader valve MTB equipment This mountain bike is equipped with a bell, lighting, wheel reflectors and flat pedals. The frame is also compatible with other B'TWIN accessories: - front and rear mudguards - kickstand - bottle cage - bicycle bag - stabilisers https://www.decathlon.fr/p/stabilisateurs-velo-enfant-20-24-btwin/_/R-p-302106?mc=8550741&c=NOIR Dimensions of the bike ready to ride Length: 140 cm.
