Children's bike, scalable
Thanks great product
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.
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
I have always chosen decathlon bikes for my children for years and there have never been any problems
Good
I bought the product as a result of long researches. We love it highly recommend

Additional Product Information
Composition
Bike frame: 100.0% Steel
Frame
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.
Brakes
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.
Position
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.).
Drivetrain
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.
