Comfortable bike, nice color, light enough for a child's bike. The gear change remains simple but could be more ergonomic.

Good optics

The bike is an eye-catcher. At the age of 8, the little one can just about cope with the deepest saddle. Driving behavior is good. The two additional brake levers are very good.

A brilliant bike!

I'm a 27 year old woman, but i'm quite petite! I found this bike via extensive research (and yes, I know it is technically a teenager bike), but it doesn't look like a teenager bike, it's easy to ride, it has great functionality and it moves quickly. My only negative point is that the gears can be a bit slow to switch overall, but this has been easily rectified by just going up and down a gear again.

It's great

It is a bicycle that meets all the expectations for a 7-year-old boy who practices cycling as a beginner.

Very good in price and performance

Unfortunately, my son felt unsafe on the racing bike, so he returned. Personally, I found the workmanship, despite the small damage to the paintwork, and the equipment of the bike to be very good for the price. I would recommend to any kid interested in a road bike. Unfortunately it came quite late because DHL had stored it for a long time. The reason for not having found the place of delivery was not clear to me. We live centrally, everything arrives with us. But Decathlon can't do anything about that. We quickly received a replacement delivery - but unfortunately we had to send the bikes back.

A defect, rear wheel attachment with bolt...complicated in the event of a puncture. An advertising can offered would have pleased the child.
