Product feature
  1. 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 and designers have designed a brake lever closer to the handlebars that is easier to hold. The brakes are now in reach of little hands!
  2. 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.
  3. Changing between the 5 speeds
    This bike is equipped with a grip shifter to change between the 5 speeds: an easier and safer system as the child doesn't let go of the handlebars. Changing gear according to the type of terrain is easy as pie!
  4. Frame designed for MTB
    This robust steel frame is designed to overcome obstacles on all your MTB outings.
  5. 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.
  6. 20" wheels and MTB tyres
    The tyres are designed for mountain biking. The side lugs provide good grip when turning. The recommended pressure is indicated on the tyre sidewall. 20-inch 1.7 to 2.2 cross-section inner tube with Schrader valve.
  7. MTB fittings
    This MTB is equipped with a bell, lighting, wheel reflectors and a derailleur guard. The frame is also compatible with other B'Twin accessories: - front and rear mudguards - stand - rear pannier rack

    Used for 2 to 8 weeks
    Bought this for my son's 6th birthday; he's quite tall & he loves riding it. Lighter that many other bikes of this size.

    Very good service from Decathlon.
  • brilliant bike

    Fantastic bike for my 7 yr old son. He is wobbly due to medical issues and this bike can take stabilisers. Very useful for those older and heavier kids who still need them. Staff were so helpful in the purchase and put the bike together perfectly instore for us to pick up. The bike itself seems great; fun colour, good brakes, has a cool look to it. Seems light in comparison to other bikes with this size, unless you go for the super-expensive brands. We love it!
  • Bike for a boy

    Daniel (United Kingdom)
    Used for 2 to 8 weeks
    Bike is great for the price, if a little heavy...
    But the preparation of it was atrocious:
    Handlebars loose
    Cables not adjusted
    Plastic guard on the chainring was so loose it fell off in the car on the way home.
    Rear wheel binding on the brakes as out of true
  • Great bike
