used for 1 week or less I bought this bike yesterday because I thought it was a good trade-off quality/price for a beginner. I tried it in the decathlon parking and it seemed solid enough, After only 2 hours, the seat started to tilt and few minutes after also collapsed (in the city traffic). Furthermore, the gear didn't work properly on the road. Fortunately I was helped by friends to temporary fix few parts and adjust the gear. Surely I need to come back to Decathlon workshop for completely fix the seat part.

Response of the brand

Hi Andrea,

Sorry to hear about the issues you've had with the bike already. I would 100% recommend you take it back to your local store to have the seat clamp/post replace to stop the seat from tilting while riding.

used for 7 to 12 months Great bike for my 12 year old girl (I know but teenagers start early!). Looks great and good quality parts for price. A little heavy for lifting onto bike rack is only downside.

Lasted less than a week

used for 1 week or less I was tempted by the price of this bike, it seemed solid enough but sadly a known fault in the seat assembly caused the seat to tip backwards throwing the rider off. It was returned for a refund
