I've recently purchased X8 Rockrider 5.3's for use with my 'Freedive and Fitness' business on the Isle of Benbecula.
I decided to go for the Rockrider 5.3 after reading a couple of good reviews and researching the bikes specifications.
I have to say that these bikes really do Rock!! They sure hit the mark and go further still!
Superb riding position, very light, awesome sophisticated fast response and handling over rough troublesome terrain!
Service I received: second to none! A five star b

Maintenance Manual

Nice and Light & Easy to Use

Brakes often squeaky and saddle could be softer

Overall I am very content with my purchase, however, I am disappointed that the service provided when purchasing my bike was minimal and I did not receive maintenance manual or a toolkit despite requesting one. So it looks like I'll definitely be making use of my free service option

Response of the brand

Hello EJ,

Thank you for taking time to give us your feedback.

Great to hear that you enjoy your bike. I am sorry to hear that you were not happy with the service provided. Our stores usually do not provide any tools with your bike purchase, as we set up the bikes in store for your fit. Of course, you can take the bike anytime to your local store if you need further adjustments. If you still require a tool, please contact our Customer Loyalty Team.

The user guide and other useful information can be found at BTWIN's website.

We see you at your free service check;)

Yours sportingly,
Customer Loyalty Team - Decathlon

Great bike so far - just a few teething problems

Nice looking, good quality

Nothing really, bought higher stem to raise bars


  (United Kingdom)


5 5

Ordered on-line last summer & arrived in good condition with a small area of paint missing where the Sram attached to frame (assembly?) No protective packaging on bike and both bike and tools were loose inside the box! The Alan key supplied was the wrong size for straightening the bars but I had one anyway.

The rear break was rubbing so adjusted myself (cable tight rather than pads miss-adjusted) but otherwise great! - gears superb, wheels true and tyres fine for road use, no punctures yet!

Great Value

Handling, brakes, gears, fork

Nothing so far

Had this bike a week now in the large size. It`s a lot of bike for the money. Relatively light for the price-range. Cable disc brakes are effective and quiet so far...a bit of tweaking with the adjustment can yield great results! Fork features lock-out which is great on the smooth fast stuff. Gearing is responsive with a good range. The tyres are great...I planned to change them for an intermediate model as I also use the bike for commuting but they`re fast on roads, so no need. Excellent!
