Store Availability

We have designed this mountain bike for children ages 6 to 9 (120 - 135 cm tall) who go mountain biking regularly.

To ensure riders can easily overcome rough terrain, we've equipped this 20-inch MTB with a suspension fork. Easily overcome hilly paths with the 6 speeds.

BENEFITS

Ease of use

Equipped with a grip shifter to easily change gears (6 speeds).

Brake control

New Easy break brake levers are sized for children's small hands.

Efficiency

Suspension fork. Skinwall tyres for less weight, with side knobs.

Cycling comfort

A saddle with a sporty design, sized especially for kids.

Instructions


TECHNICAL INFORMATIONS

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.

Bike accessories

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

Excellent quality bike (I needed two for my twin grandsons) for Christmas. I had seen bike online and was staying with my daughter in Suffolk when we visited Cambridge Decathlon to look at bikes, I was so impressed by both the bike and the helpfulness of staff I purchased immediately.

Very strong bike, but the accessories like mud guards were very flimsey. Buying of helmet fitted when bought within weeks became small and could not extend the straps anymore, The bottle holder recommended does not hold properly, Bit disappointed as this was bought for my Grandsons birthday and he chose the extras which your sales advisor advised.

I bought my son a bike for his 6th Birthday. He sat on it and the seat wasn’t fitted properly so I thought nothing is it and fixed it myself, he hadn’t ridden it for more than 5 minutes and the peddle fell off.
Either the parts are faulty, or the staff member is.
