Response of the brand

Dear Sir,
You should have received a till receipt and your registered your bike with your customer card when you purchased the bike from us. The warranty follows the bike and not the owner as long as there is proof of purchase:
Lifetime warranty on the frame, stem, bars and seat post.
Two year warranty on the parts if they are defective (excluding normal wear and tear).
Tyres, inner tubes, cables, brake blocks, handlebar grips, chain (consumable parts) are not covered unless they are faulty (which is normal).
You also get a free checkup anytime withing the first 3 months at any one of our stores.
I hope this helps. Hope you enjoy your new b'Twin bike!
Regards,
Peter Lazarus UK Cycling Market Manager DECATHLON

used for More than 1 year Very good bike. I ride him in the woods and mountains. Driving on tarmac, gravel, mud and sand. I start in the MTB competitions. The front gear is a pain if not properly adjust the requirements. With SPD pedals it is wonderful. Super looks. Convenient and comfortable. I would recommend this bike.

Amazing bike, superb forbthe money :)

Absolutely love the bike, had my first ride on it today, rides flawlessly, really light weight, brakes work sharply, gear changing is flawlessly smooth, no Chan slap when on rougher ground, the lock out forks are a godsend :) and the overall finish of the bike is stunning, lush sporty geometry and love the matte black finish, would definitely recommend it :)

Nice, but....

Brakes, not too heavy, front suspension

used for 1 week or less We bought this for our daughter. We didn't want to spend a fortune but wanted to get something she could use on trails. It seemed to fit the bill but on the first hard climb, the chain broke. Not really sure what Decathlon can do about this as I would not trust the same SRAM chain again.
