Ease of use

Single chainring drivetrain, easy-to-mount frame, child-friendly brake levers.

Efficiency

26" wheels, aluminum frame.

Brake control

Two V-brake pads for effective braking

Frame designed for mountain biking

We have designed this frame in aluminium for more comfort and less weight. The pronounced tilt of this frame, combined with 26" wheels, makes it suitable for children from 135 cm to 150 cm tall: The low frame means that young cyclists can easily get on and off their bike.

Why have 26" wheels?

Because the wheels have a larger diameter, they glide over roots and rocks. On downhill tracks, the frame stays more horizontal, making it easier to steer. Bigger wheels are also more efficient, because you travel farther with each turn of the pedals!

Changing gears: A single chainring like the pros!

The single chainring is easy and efficient to use: 1 chainring guard with 34 teeth and 7 speeds (MegaRange 14-34 freewheel). With just 1 shifter on the handlebars, shifting gears is easy. The trigger lets kids shift up and down with just one finger. The gear ratios make it easier to accelerate on the flat and tackle climbs.

Controlled braking!

We designed a brake lever close to the handlebar, easy to grip, as children have smaller hands than adults.The lever is made from aluminum. The levers are connected to two V-brake pads. They are composed of 2 callipers that exert pressure on the rim to slow or stop the rotation of the wheels. The pressure depends on how hard you squeeze the brakes.

Front suspension

The front suspension helps you easily learn to tackle obstacles on slightly uneven trails.

No rear suspension

This mountain bike has no rear suspension. It is a semi-stiff mountain bike: perfect for beginners taking their first trail mountain bike rides as a family. Compared to a full-suspension mountain bike (with rear suspension), the advantages are clear: this mountain bike is lighter! you lose less energy on flat ground.

Reinforced, ergonomic saddle

A saddle with a sporty design, carefully designed for kids. Equipped with a plastic cover at the back to protect from impacts.

Crankset

The new aluminum chainset has a 152-mm (6") crank that is suited to a child’s leg length. This light chainset allows kids to start pedalling more easily. The double guard stops the chain from jumping.

Handlebars, stem, grips

With a stem that tilts 15° upwards, the riding position of the EXPL 500 26" is raised, accessible, and comfortable. More details: - 60-mm (2 1/3") aluminum stem with an angle of 15° for maximum comfort - 580 mm (23") steel handlebars, designed for kids’ shoulder width - Soft Touch lock-on handlebar grips

Wheel/tire information

The special B'TWIN 26 x 2.00 tyres are grippy and comfortable when mountain biking. The recommended tire pressure is shown on the sidewall (between 29 and 43.5 psi) We have made the front wheel easy to put on and take off so that it’s easy for you to transport this bike. Equipped with a quick-release system. 26” wheels and 1.7 to 2.2 cross-section inner tube with Schrader valve.

Mountain bike fittings

This mountain bike is equipped with a bell, lights, wheel reflectors, and platform pedals. The frame is also compatible with other accessories: - front and rear fenders - stand - bottle cage - bag

What if I order online?

If you opt for home delivery, this bike will be delivered with the pedals removed and the handlebars unscrewed for the best transport conditions (instructions and tools included).

Dimensions of the assembled bike

Length: 168 cm (66"). Height: 100 cm (40"). Width: 60 cm (24").

Bought this bike for my 8 yo. 131cm tall. Looked big but fitted him well. All the components were very good. It was this bike or a Halfords Carrera. This was better in every way. All the controls are well thought out for smaller hands. Service was very good. Bike was bell grea

sed up and all the fixings were torqued up by the mechanic. Highly recommend

The quality of the product and bike build is fantastic. This bike is superb value for money and very easy to complete the build at home. The packaging used was both protective and easy to recycle. My daughter adores this bike and is looking forward to many years of happy off r

oad riding. I would definitely buy bikes through Decathlon again as they are comparable to some of the best suppliers in the UK; I am a bit of a two-wheel junkie and know when I see a good build.

My son personally picked this bike so was over the moon when Santa gave it to him for Christmas. The bike looks fab, received lots of positive comments and he loved riding it most days. One of the pedals came off and the thread has completely gone in 3 weeks. Very disappointe

d in the quality.
