Concerned about quality

used for 3 to 6 months Purchased for my son end of May 2014 from Southampton store as had seen great reviews of the product.
All was fine until recently when the duralier got caught in the spokes during gear change (son doesn't normally use gears and I had encouraged him to start!). Duralier is broken, there are a few loose spokes , damage to the saddle and handlebars, plus a flat spot on the tyre.
I spoke to the store, a guy called Jean, and he was brilliant and has asked me to bring it in for it to be fixed.
My concern is whether the bike is up to the job longer term and whether all the things that were damaged when this happened will be repaired or replaced.
We'll see...

Response of the brand

Hi James,

I am sorry to hear about the damage to your son's Rockrider 5.  I'm sure you're in safe hands with Jean but if everything is not to your satisfaction with the repairs don't hesitate to get back in touch.  The bike is not designed for intensive use so the moving components (tyres, gears, bearings) may wear quicker than on the bikes designed for more intensive use.  All parts and forks are guaranteed for 2 years against defects and the frame comes with a lifetime guarantee so I hope this reassures you.

Kind regards,

David Daker Commercial Director DECATHLON

Superb value

Value for money, useability

used for More than 2 years So you can only get a "bike-shaped object" for this price? Well, I'm not an expert cyclist, but when I bought this bike its sheer useability re-ignited my love of cycling. I decided to go for a cheaper steel-framed bike rather than an alloy one with front suspension, which weighed the same. I think this was a wise move and I rarely miss the suspension, or at least the sort you'd get for this money. The bike is well-made, with good components, though I did replace the saddle with a gell one. It is ideal for country roads, forest tracks and canal towpaths, with a good range of gears for hauling you up hills. To cap it all, the guy in the Glasgow Fort store who sold me it (2 years ago) knew what he was talking about, advised me well and set the bike up properly for me. The most important thing about this bike is that, unlike some at this price, it won't put you off cycling. Quite the opposite.

Fell apart on first ride

I'm unable to give a proper review of this as a bicycle as I've not been able to actually ride it properly due to the number of faults that I've encountered. First bike was delivered with a broken derailleur and was replaced very quickly by decathlon. The second bike developed a fault with the crank arm, which fell off after less than ten miles whilst cycling on what was thankfully not a very busy road. Very disappointed in this bike.

Response of the brand


We seem to have come up short regarding the pre-dispatch inspection on this occasion.

We will be in touch with you very quickly to find a solution.

Please accept our apologies for this.

To follow up on the review below, I took the bike to the workshop, and after half an hour working on it, I was told it was a simple screw adjustment for front derailleur and replacement cable for rear. (bike only 4 months old) After testing next day, front derailleur problem exactly same. Took bike back today and now it is being kept in workshop for at least 5 days as there has been a fault diagnosed, which on inspection is very clear to see. 4 months old, 3rd visit for repair. Not great.

Response of the brand

Dear Sir,

Sorry to read that you've encountered issues with your bike.

It is not uncommon that gears require adjustment early after purchase as the cables do tend to stretch. However if there is a fault with the part, then indeed it will be covered under our two year parts&labour warranty under normal use.
