Technical Information

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!
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.
Changing between the 5 speeds
This bike is equipped with a grip shifter to change between the 5 speeds: an easier, safer system as the child's hands stay on the handlebars. Changing gear to adapt to the terrain is easier than ever!
Frame designed for mountain biking
This robust steel frame is designed to overcome obstacles on all your MTB outings.
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 against any impacts.
20" wheels and MTB tyres
The tyres are designed for mountain biking. The side lugs provide good grip on turns. The recommended tyre pressure is displayed on the tyre sidewall. 20-inch 1.7 to 2.2 cross-section inner tube with Schrader valve.
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

Bike heavy and dangerous set up caused crash
Used for 1 week or less
Bike is ridiculously heavy for a child to use when compared to my other children's bikes - but real issue is the way it came set up. Basic safety checks had not been performed. I spotted the brakes didn't work in store and got those correctly adjusted upon collection. Kicking myself though as a did not spot that the stem was very loose, so on my son's first ride on Christmas Day it came loose whilst riding causing him to crash and hurt himself. He has not wanted to ride the bike since. I will think very carefully before buying any bike from Decathlon again.
Response of the brand
Dear Sir,
Thank you for taking the time to post a review of this kids bike.
The bike weighs 12.2kg which is in fact quite competitive compared with similarly priced bikes on the market.
I see that the bike was set up by the store team. I will contact them regarding this matter. I urge you to contact them as well.
I can only apologise for this level of service which is not acceptable.
Peter, Cycling Manager, DECATHLON

Does it have 5 gears or 6 gears?
Is it a 320 or a 500.

Who know, im sure i dont.

Im still buying on though
excellent value for money
Used for 3 to 6 months
Kids don't respect their things at this age, so we've not paid over the odds for a bike to be trashed. This fits the bill perfectly.
Great bike
Used for 7 to 12 months
Excellent bike with light and bell’included. Great 5 gears and very easy to get use to. But we should have bought bigger size. My not quite yet 7 is very tall. He had it only 9 months. We underestimated how fast kids can grow in the summer. (Two shoe sizes in less than a month) I think my boy is no exception!
