Product Customer Reviews

Best of all, my son loves it
Excellent bike, ok price
Everything as we expected
Good bike overall (quality/price ratio). The braking system is not the best. The gear ratios and ratios are a little lacking when shifting: sometimes it is necessary to force the gear knobs beyond the limit. Probably a matter of setup. With a little attention it could become a very reliable product. Structurally robust bicycle.
This magnificent mountain bike will go into Santa's sack to spoil my 10-year-old granddaughter who was able to test it before choosing it. This year again, Christmas will be a successful celebration and it will also be thanks to Decathlon and its fantastic teams.
Brilliant
Nice bike to take with you. Very good value for money
Perfect, light
Super
I bought this bike for my son. This will be his future Christmas present in 2023. When purchasing, I ask the seller to sort everything out properly because I had a bad experience with the previous bike purchased new, the Rockrider ST120 (loss of a pedal during the 1st exit) Arriving in our underground garage, my child tests the bike. It made an incredible noise when braking. He takes a little speed bump and boom, the saddle suddenly goes down. Still disappointed by Decathlon and its Cycle department. In the afternoon, I return to Decathlon to check the brakes. I was told that on this bike, it always makes a horrible noise when you brake because the brakes are painted!!!! Fortunately I came across a lover of his profession in the store's workshop. He spent time to significantly reduce this awful noise. A big thank you to this gentleman! We agreed that if the bike made noise after 2 or 3 rides, I would go back and see it.
This is my child's second bike, I bought them both from Decathlon. I am very pleased.
I recommend this bike 100%. Very easy to use and extremely beautiful physically and there you have it⭐⭐⭐⭐⭐
A happy child
my son is very satisfied with it
My son loves it

Additional Product Information
Composition
Frame (for bike): 100.0% Steel
A frame that is suitable for mountain biking
Our engineers have designed a new, robust steel frame. The frame's rear chainstays are short to make the bike dynamic 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 between the 6speeds
This bike is equipped with grip shifter to make it easy to change between the 6 speeds - more precise control over your pedalling.
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 cover at the back (a bumper) to protect against any impacts.
Riding position
To provide you with maximum comfort, this mountain bike is equipped with a high-rise stem. Your position on the bike is slightly raised so you can better anticipate your trajectory.
Crankset
The new chainset has a 152 mm crank that is adapted to the length of your child's leg. This chainset allows you to start pedalling more easily. The crank is covered with a guard to stop you coming into contact with the metal part.The double guard over the chain stops it jumping.
24” wheels and skinwall 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 use SkinWall technology. This process reduces their weight and makes them more flexible, which increases performance, grip and comfort.The recommended tyre pressure is displayed on the tyre sidewall (between 2 and 3.5 bar).24-inch 1.7 to 2.2 cross-section inner tube with Schrader valve.
