Decathlon quality, and very beautiful too!

Bought for my 8 year old son. He is 1.27m tall and the bike is still a little big for him, but as he is comfortable on a bike, he already uses it. His previous bike was not a decathlon and we regretted it! Decathlon is a guarantee of quality and compatible accessories are easy to find! This bike rides great and my son loves it. in real life, it is more beautiful than in the photo!

Certainly a little expensive but this mountain bike is still great for putting your child in the best conditions for learning mountain biking. Impossible to raise the handlebars it is at the maximum but that is not a problem in itself.
