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 gears
    This bike is equipped with a grip shifter to change between the 6 speeds: an easier and safer system as the child doesn't let go of the handlebars. Changing gear 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. 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 side lugs provide good grip when turning. The recommended pressure is indicated on the tyre sidewall. 24-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 pre-drilled to attach a bottle cage if needed. The frame is also compatible with other B'Twin accessories: - front and rear mudguards - stand - rear pannier rack

    £120 for a 6 gear kids bike. You know they don't respect things at that age so we've not paid over the odds for an expensive bike to be trashed. This one fits the bill perfectly.
  • Excellent bike

    Bought for 8 year old granddaughter as a birthday present and she's never off it.
  • Versatile bike but only average build quality

    ANTHONY (United Kingdom)

    Bought this for my 8 year old for his birthday and he loves his cycling. We made a 160 mile round trip just to collect it. The first week he used it the front brake fell apart on several occasions (4-5 times a day) which was obviously dangerous. In order to get it repaired I had to do another 160 mile round trip, 4 hours wasted back to Glasgow.

    I was told that if it happens again (re-assuring) then there is no point in going back. I had to phone them and they would tell me how to fit it over the phone. Couple of issues with this; I know how to fix brakes and it is not a repair but a replacement part that is needed. Secondly, if it is a further repair then why not tell me when I was in the shop how to fix it?

    So, I am effectively left with a kids bike that my son is not keen to ride (the brake has fallen apart a couple of more times since the repair was done), that the shop does not want back and the only effective way to repair it is for me to spend money on replacement parts...

    I could have spent a little more on a similar bike but bought it locally. This way I would not have to waste time and money to keep getting it repaired.
