I am usually a big fan of Decathlon products. But I did NOT like this bike. I ordered it online wihtout seeing or trying it on in person. I was looking for a folding bike, and this one looked great online. The delivery was FAST, I got it the same day. The bike came fully assembled, however, the wheels had no air, and I forgot to buy a pump. So I had to order another pump and wasn't able to use it the next day. The seat was also SUPER hard as another reviewer mentioned, so I also ordered a gel cushion from Decathlon - size M, and it fit perfectly, I was very happy with the gel seat. I was worried about the folding mechanism, as I have never owned a folding bike before, but surprisingly, it was easy to fold down the handle bar, and easy to fold the bike in half. All good.... the color was even more vibrant in person. However, what I really did NOT like about the bike was the handle bar and brake system. The hand brake - if you look closely at the photo, is actually under the the handle, which is not very intuitive and not very easy to use if you have smaller hands. Most brake levers are in front of the handle bar. Secondly, the handles are NOT height adjustable, while the seats are. So, for a smaller person (I got the bike for my 12 year old), the seat can be adjusted to fit anyone, BUT the handles remain very high and hard to reach, add the difficult to use brake lever, makes for a very dangerous and hard to control bike that I would NOT recommend to anyone.
Decathlon customer service was excellent, as always, and took the bike back, even though we already tried it on outdoors for 15 minutes. Wow, that is rare for HK stores, so I am a loyal Decathlon customer for life....

Pretty good, good service & helpful staff

Superb

Got the Btwin 120 folding bike the other day, took it out of the box and the folding/unfolding mechanism was fine. But I realized that the entire V-brake built was poor and unacceptable. I am saying this fully understanding that I bought a HKD1,299 bike but it is still unacceptable and not safe to be on the road. Firstly, the brake pads are rubbing against the wheel right out of the box. Secondly, the pull of the arms are unequal and the entire braking mechanism is simply flimsy. Perhaps I got a lemon but there is no way I'm taking this on the road. Sending it back this afternoon.

Decent bike. Rides very well. Gear Changes can be quite tricky. If you are on the larger side like me, should buy the memory foam saddle as the original one is very hard and you will feel discomfort after a while. :)

Very disappointed. An online order (hk83936739) on 04/17 and confirmed delivery on 04/18. No delivery finally and no pre-notified before i asked twice to you. I planned to have a family cycling on 04/19 (Sun) but now, ruined. Totally crazy!!

Use it often for short rides / errands..The bicycle is comfortable and smooth.. However the paint job on the bicycle is very bad ..within one year there are bubbles, the paint is flaking in places and rusting has started in some places.... nowadays this does not happen in cheaper bikes, let alone something costing 15k.. below expectations

Seat is expandable but need to set frequently and come down with every breaker. Need to work upon it

Stylish and comfortable, easy to ride, little expensive but quality products

Seat is small, uncomfortable beyond 15-20 mins
Accessories are limited. UK decathlon had front and back lights, not available here https://www.decathlon.co.uk/p/tilt-front-rear-bike-light/_/R-p-200192

Had the chain slip off a couple of times - just watch out for a knocking sound while shifting, you know the chain will come off

Tyre doesn't seem to be of great quality - don't expect it to last beyond 6-9m max
