Embarrassing!

Got this (from Santa) for my 6 year old. Pedal fell off on first outing! How dyou explain that to a child. Would give 1 star but I’m giving decathlon the benefit of the doubt that maybe this was just an oversight by the ‘elf’s’.

Christmas bikes for Twins

Excellent quality bike (I needed two for my twin grandsons) for Christmas.

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.

Additional Product Information

Composition

Bike frame

  • 100% Steel

Frame designed for mountain biking

Our engineers have designed a new sturdy 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: It's safer and easier for children as they don't need to let go of the handlebar to change gears. This makes changing gears to match the terrain simple and easy!

Controlled braking

2 V-Brake pads for effective braking. These brakes are composed of calipers 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 cover at the back (a bumper) to protect from any impact.

Crankset

The new chainset has a 140 mm crank that is designed for a child's leg length. This chainset allows you to start pedaling 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 tires

The tires are designed for mountain biking. The lateral lugs provide good grip on turns. The tires are made with SkinWall technology. This process reduces their weight and makes them more flexible, which increases performance, grip and comfort. The recommended tire pressure is indicated on the side of the tire (2 to 3.5 bars). 20" inner tube, 1.7" to 2.2" Schrader valve.

Bike accessories

This MTB is equipped with a bell, wheel reflectors and platform pedals. The frame is also compatible with other B'Twin accessories: - front and rear mudguards - stand - bottle cage - saddle bag - stabilizers

Dimensions of the bike ready to use

Length: 55.1". Height: 31.5". Width: 21.3".

Origin

Imported

Storage instructions

Store the bike in a clean, dry place. Clean and grease the chain regularly. Our advice for before each ride: inflate the tires to the pressure indicated on the sidewall.

Guarantee

Lifetime (frame, stem, handlebars). Find out more about this bike's warranty.
