Child's bike with stabilisers

Very impressed with the solid build of the bike and the care taken to go through a checklist of adjustments before purchase. The stabilisers were easy to fit. The back brake was binding a bit so it did need some further slight adjustment but otherwise all good.

Very poor quality

First day front brake got broken. Too heavy and my daughter do not use it anymore. Waste of money

Excellent for my ~4 year old son!

Every single thing is awesome about this product - the look, the build quality, the adjustable seat height & removable stabilisers. The staff was very supportive about all our queries. My kid is loving this so we both are very happy about this purchase. Also great value for money compared to other options. Keep it up Decathlon :)

Kvalitní kolo pro děti

Kolo je precizně zpracované, výhodou jsou odrazky a světla, blatníky proti bahnu, kryt na řetěz. Nevýhodu vidím ve váze kola, je poměrně těžké. Dítě samotné jej jistě neodnese, děti nevydrží dlouho jet.

sehr gutes Preis-Leistungs-Verhältnis

Wir haben das Fahrrad für unseren Sohn (knapp 4 Jahre alt und ca. 100 cm groß) gekauft und er fährt damit hervorragend (ohne Stützräder). Es ist auch nicht zu schwer, sodass er damit sehr gut zurechtkommt.

Tolles Preis/Leistungsverhältnis.Rad leider schwer

Für den Preis ein Top Angebot. Kette Nachspannen etwas fummeling. Durch die Rahmenform ist ein leichtes auf-/absteigen möglich. Das Rad ist recht schwer, es wird ab und zu Unterstützung gebraucht, eben kein Boom bike. Konnte gut weiterverkauft werden.

Ideal als lern Fahrrad

°sehr leicht °sehr bequem Mein Sohn hat sich in 3 Minuten mit dem Fahrrad fahren gelernt


leider zu früh gekauft. In dieser Saison kam unser Sohn damit nicht zurecht da das Fahrrad für ihn zu groß ist. Leider war hier die Beratung nicht ausreichend

Tolles Fahrrad für unseren Junior.

Sind total zufrieden mit dem Fahrrad. Tolle Verarbeitung und Räder drehen sich leicht.

Fahrrad für 4 Jährigen

Ein super Fahrrad. Die Verarbeitung ist voll in Ordnung, vor Ort würde es noch auf den Jungen Mann angepasst und seit dem können wir nirgendwo hin ohne das Bike. Er ist zu Frieden, ich bin zu Frieden, wir kommen wieder.

Top Produkt

Unser Sohn hat das Fahrrad zu Weihnachten geschenkt bekommen, zwar wurde es noch nicht groß genutzt, doch es hält was es verspricht.

Fahrrad Kinder

Etwas zu klein für unseren Sohn mit 111 cm. Der Sattel ist von Anfang an auf der höchsten Stufe. Wir würden leider nicht so gut im Laden beraten. Das Fahrrad selbst ist aber super! Kann absolut mit puky mithalten.

Additional Product informations



  • 100% Steel

Stop easy innovation: a patented braking system designed for children.

More accessible brakes and a more comfortable grip are the main benefits of our Stop Easy system. For more natural movement, the brake lever is pressed parallel to the handlebars. Whilst progressive, this innovative brake lever also provides 30% more braking power compared to a conventional brake lever. An innovation from our B'Twin team, loved by both parents and children.

What type of braking system is equipped?

Brake efficiently thanks to the two V-brake brake pads.These brakes are composed of callipers that exert more or less pressure on the rim to slow or stop the rotation of the wheels.

Wheels / tyres

Tyres with an inner tube (inflatable) and knobs. Their shape gives them a good grip on everyday terrain (paths, grass, etc.).

Can stabilisers be added?

Yes, if your child needs them. Our 16" B'Twin stabilisers are compatible with all our bikes in this size. Practical, they can be mounted and removed from the bike without tools.

What about comfort?

We've carefully considered children's morphology: the width of the handlebars and the diameter of the grips are sized for their small hands. The foam saddle provides a comfortable seat.

A bike that grows with the child

The saddle is height-adjustable (using a size 6 Allen key) so it can grow with your child.The saddle height can be adjusted from 48.5 and 60cm.Our bikes meet the Children's Bike standard (ISO 8098), which is why we cannot offer a tool-free (quick-release) saddle height adjustment system.

What is a guard for?

To prevent children from putting their fingers where they shouldn't, the mechanical elements of the drive train (crank, chain, freewheel, etc.) are surrounded by the guard. It also prevents the risk of laces getting caught and clothes being dirtied.The decorations are set into the plastic of the guard for greater durability.

What accessories are supplied with the bike?

A bell, front and rear light, wheel reflectors (reflective parts attached to the spokes).
