derailleur is rubbing with chain
Used for 2 to 8 weeks
After a couple of rides only , I started feeling lag in shifting gears.
Even with that I compromised.
Then after a week the the cracking sound from the derailleur both front and rear keep annoying and derailleur is rubbing with chain and making moice.
Now in the 2nd week only the gear is giving issues.
It skip one gear either 3 or 4 or 5 while going up and down both way .
Its making noice while changing front gear.
and front gear is not properly changing
It's really frustrating that even such a brand new piece which I did not even rode properly
Overall okay but use sparingly off road
Used for 1 week or less
Was riding v modestly, in a park on grassy land, and suddenly a bump came which i chose to take, it was not a big one, and as soon as bump came, i peddled a bit to not get stuck behind bump and snap, chain broke, leaving me chain-less to face the bump, result was a broken chain and scratched knee.

In other categories, bike seems fair for off-roading as of now.
Just amazing. Loved b twin cycling
Used for 2 to 8 weeks
It's amazing experience to ride rock rider. I just feel the smoothness of the cycling and its gear system is amazing. Every morning I just wait for riding the cycle. Realy worth it.

It's really frustrating that even such a brand new piece which I did not even rode properly for 50 -60 kms is throwing up issues.

Decathlon expected a much better product from your side and to be really honest my trust for quality product from you is shaken.

I asked some cycling experts on YouTube , almost all of them advise me otherwise but even I went with my choice of btwin.

I realy love biking and have been sacrificing a lot other stuffs to carry on my passion but this issues are a big deterrent to my goal.

Decathlon please help on this issue.

The bike quality is really good and riding it is nice but the gear shifting system in the front should be overlooked because there are 3 gears but the gear shift has 8 node which makes the chain to go out the 3 gear.
Great product I have ever purchased
Used for 2 to 8 weeks
This is the best buy from my side, it has the great smoothness which make your ride comfortable in one sentence it's worth the money
Not value for money
Used for 1 week or less
The cycle is average. It has gear issues, just four days the chain came off. The seat is very hard even with the cover on. Overall not satisfied with purchase ( Decathlon whitefield.)
Very good product.
Used for 2 to 8 weeks
I bought this cycle in May. I have cycled 200km in total and the problem i faced was the handle's screw becoming loose and was turning. The gears are awesome. only once i faced some delay issues, else they are just awesome. The breaks perfectly fine and the tyres too.
I suggest the producers to strengthen more the spokes are they are more vulnerable to wheel bend.
i am enjoying the cycle very much.
Just ok with discomfort
Used for 1 week or less
I am starting to cycle again after 10-12 years, and this time I opted for a geared cycle from decathlon . This is a very good product with initial trial of 5 mins from the store itself . But real issue comes out when you take out cycle coz seat is not at all comfortable, pain arises in lower abdomebmn due to seat.
Further decathlon folks in Pacific mall tagore garden are not sensible enough. They wish customer to quickly make a decision and do not entertain the questions properly.
14 points check is just the formality ,as I got to know new cycles need not go through it LOL. NO body tried to explain me how to use the gears being a new bee in this category.
I have been using it since 1 week and now metal sound is coming from the front junction between handle and tyre.

So decathlon needs to look after all these items if they wish not to lose their customers
