Response of the brand
Hello Sandeep, 

Thank you for taking the time to give us your feedback. Apologies for the wrong information provided. The bicycle can be ridden on distances which best suits the cyclist. What I meant by that is, the bicycle will go as far as the cyclist wants to go. The Rockrider 340 can be used for long distances, provided it is serviced at regular intervals. Any problem related to the bike must be addressed at the earliest to prevent other parts from wearing out as well. The drive train problems can arise depending on usage. It can definitely be fixed in the workshop. I suggest you do give it a shot again explaining what I have mentioned do let me now if your problem is still not solved. I remain available.

Using rockrider 340 since 3 weeks. Best bike for city as well as offroad touring. Charming looks, very comfortable to ride. Feel of owning a premium product. Gear shifting is not bad, actually you need to get used to its settings, don't expect that if gear shifter points at 2 then bike is on 2nd gear, it may need a twist upto 2.5 and likewise. Even I had a complaint of pain in crotch bone on first day, I blamed saddle and its hardness but I read some opinions on this and continued cycling and found that, those who are cycling after a gap of more than a year may have this problem but continue cycling, the pain will vanish.
Used for 1 week or less
The BEST ONE there is.
Used for 2 to 8 weeks
I have purchased this for 3 weeks now. I must say this is one of the BEST available bicycle. I would definitely recommend this. The gears are very good & if you ride it with good knowledge of changing gears, then i am sure you'll have an amazing time riding your cycle.
Great Bike,Nasty Saddle
Used for 1 week or less
The bike is great its lightweight so carrying it down or uphill on bad trails is easy,nice brakes,easy shifter.The bad thing about it is the saddle,it will give you a sore behind,i'd suggest get the saddle replaced with a better one.
Shifter's are simple
Nasty Saddle
Doing quite well.
Used for 1 week or less
I've been using this for a little less than a week now. The gear system took some time getting used to but, since it was well explained at the store, if the guidelines are followed correctly, it works like a charm. The quality of the product is very good as well. I haven't had the product for enough time to get it serviced but, I hope to have a smooth run with the service people when it comes to that.
The only hitch is that the cycle doesn't come with basic accessories. A lock, a bell and a stand could've probably been included as part of the default package.
Otherwise, a fine product.
Overall quality
Lack of basic accessories inclusive of the package
Nice look, Gear system is not smooth
Used for 2 to 8 weeks
I purchased btwin 340 at great price . Cycle is comfortable, however gear changing is not smooth.Normally I ride in Delhi city do not have to change gear frequently..unless I have to ride on flyovers.
Look is nice..easy to drive
Gear changing is not smooth
Great looks, Light weight with Poor gear shifting
Used for 3 to 6 months
It's been 4 months I bought Rockrider 340 from Decathlon, Pune. My daily usage is around ~10kms. The best thing about this bike is it has great look and extremely light weight. It feels awesome while roaming around the city on this bike. The worst thing about this bike is poor gear system. Sometime I switch the gear and it takes 1-2 km to reflect the change. Considering this bike uses Shimano gear kit, gear system is pathetic as Shimano is known for it's best gear kits. Verify gear switching before coming to final conclusion.
Great looks, Light weight
Poor gear switching
Excellent Bike
Rockrider is cool.
Smooth gear functioning.
Gear issues
I had bought the same bike around two weeks back from Decathlon noida and have been facing issues with gear system. The gears slip on changing making it difficult to peddle for some distance. Pls do a thorough review of the gear before buying yourself one.
