Love the the design and mfg detail of this product. Paddle Shifters are great on this 24". Also brilliant to add the derailleur guard since boys this age will typical slam the bike down. Haven't found anything to dislike yet, besides the FedEx delays on the shipping which had nothing to do with Decathlon...they had it ready same day.
Keep on continual improvement

Overall is good just that the bicycle doesn't come with bicycle stand. Never thought that such an expensive bike without a stand.

I bought this as a gift for my 8yr old son! He just loves it. The Color is great - attractive to the kids. The functions are Super - the fear shift is really smooth. My son learnt to ride the bike within 5 mins.

This is a great bike equipped with disc brakes and a front suspension fork for beginners aged 10-14years The aluminium frame is well constructed and the paint job is excellent and striking given the price paid. Easy shifting of the gears and derailuer protector against falls and dents . Valued for money .
