Kids Bike

The front brake system is very bad. I don't know why but the brake cable is coming apart from one of the brake system. In my opinion, it is a problematic and simple brake system. I plan to take it to the store as soon as possible.

Inexpensive children's bike entry with hurdles.

We purchased this bike on recommendation/advice at the local Decathlon last year Feb 22. Stand and mudguards must be purchased separately. In itself, the bike is ok for the little ones, but the advice is useless and the condition upon delivery still has potential for improvement. The chain was under severe tension and the open, unprotected hub bearings were over-tightened. The bike rolled very badly. I then had to adjust it myself. Our son was 100cm tall and could hardly ride the bike because he was too small, it didn't get any better after 2 months and he didn't want to ride it either. The seller was still of the opinion that he "grows into it". Without further ado, a 14 inch variant was also bought by Decathlon (used) and with this it is a lot! coped better. Only this year with 115cm he could ride a bike normally. The sitting position is still very stretched, I've seen this with other children as well. Few of them look really happy. We now have a model from a well-known bicycle dealer, and then all the differences are even more noticeable. The 16-inch variant tries too hard to grow with it and unfortunately only fits very late. In contrast to the 14 inch version, I would recommend a different manufacturer for the 16 inch.

Very reliable bike

Additional Product Information


Bike frame: 100.0% Steel


Exclusive new B'Twin steel frame: lower in the middle to make it easy to get on and off. Kids won't get stuck on their bike when playing as it's easy to climb on / off.


The innovative Stop Easy brakes, specially designed for kids' small hands, require 30% less braking effort than traditional levers. V-brake at the front and coaster brake at the rear for effective braking.


B'Twin handlebar and grips. Comfortable foam saddle.The riding position has been designed specifically for kids, and the grips are suited to small hands. Plus, it's height adjustable, so it grows with the kid.

Wheels / tires

Aluminum rims. Real tires with inner tubes (inflatable) to help get past obstacles (curbs, etc.).


Freewheel: safer as kids don't need to pedal, even going downhill.

Chain guard

Specially-designed B'Twin housing with decorations on the plastic.We created this chain guard to fully cover the mechanical drivetrain parts (crank, chain, freewheel, etc.) in order to reduce the risk of pinching (of small fingers) or catching (of laces), and to keep clothes clean.
