Filtered by reviews Loading reviews…

So after only having this bike for a matter of weeks, and ridden it in anger only three times, I feel I’ve given it a fair chance to bed in and prove itself. Sadly it has failed to do so. I noticed a few cracks and knocks straight away, and that was just test riding on the street. Took it back to store, and the technician failed to identify the noise. Told to take it back if it got worse. Well, three rides in, and those cracks and knocks are very noticeable on almost every rev, and worryingly loud. The bike is going back to store this weekend, and will be left with them to remedy. All in all, I’m disappointed with the ride. For the money I expected better, and in all honesty I have an 8 year old bike that I paid £100 less for that is a smoother and quieter ride than this one. Nope, not impressed at all I’m afraid.

Great Bike, poor design for adjustment.

This is probably true of many mountain bikes, but to claim that this bike fits people who vary 150mm in height is just not the case without adapting the bike. The seat stem can vary in height by 150mm without a problem, but the handlebar stem is designed to adjust a mere 10mm or even less. The consequence is that the height of the rider dramatically alters the riding position. To claim to be able to fit men between 185 and 200cm, the handlebar stem would also need to adjust by at least 100mm, if not 150mm. In this way the riding position for men of all the sizes in the XL range could be accommodated. I'm 195cm tall and will have to add to the handlebar stem and lengthen the brake tubes and gear cable, just to get the handlebars to the same height as the saddle. I'm sorry to criticize what is otherwise an excellent design, but this really needs to be thought through by the designers. How can you allow 150mm of play in the saddle and only 10mm with the handlebars?

Good bike - rubbish suspension.

I bought this bike as a good starting point. I always intended to upgrade certain parts, I just didn’t know I’d be doing it this quickly. The good points - it has a good frame (looks like pretty much the same frame used on higher range models, with the exception of the head tube, which I’ll talk about later), it has a good group set (the micro shift system has some good reviews - and it has a clutch), and the brakes are good. It rides well in terms of positioning and the wide bars give it a good feel. However, the rear shock is TERRIBLE! You get a loud knocking every time it compresses. Every bump you go over results in a clunking sound. Ride on gravel or a rocky path and it sounds (and feels) like the bike is shaking itself apart. The forks aren’t much better - they compress far too much under my body weight, no matter how much pre-load I put in them. I went to my local store and tried the same bike and the shock in the store made the same noise. I’ve since replaced the rear shock with a Rock Shox air shock and I’ve got a Suntour air fork on order. Your limited as to what forks you can upgrade to because the bike comes with a 1 1/8” straight head tube - most modern forks now have a tapered steer tube, which won’t fit without modifying the headset. So, a good bike when you look at what your getting interns of most of the components, it’s just let down by poor suspension. If your buying this for a few occasional rides you may like the suspension and you may not have a problem with it. But, if you want to do any sort of regular trail riding, either look at spending more or buy this as a starting point and upgrade the suspension.

Super Bike

Who should buy this bicycle? This is an ideal bicycle for someone looking at entry level hybrid bicycles, at a reasonable price. The bicycle is ideal for both short and long distance city rides


I bought Rockrider ST530S which is about 56K. After 3 or 4 rides, the rear tube got punctured And I thought my Off roadriding did this and sealed the punctures by myself. Then the next day after the ride, it flat back again. This time I thought the same puncture my thorns or other splinters, but it came as a shock that the spoke base pinched the tube's inner side and the city was large that, it won't retain the air for a second when it pumped. This is the moment I was fed up with this product, since the tube are very thin compared to others are the yres are also weak. Hence planning to replace both tyres and tubes. Don't even buy this.. How come they are selling this garbage, I don't know

Long lasting quality

Good to use daily

Great for beginners

Perfect choice for beginners as indian roads are no less than mountains and such MTB's are best suited. The seat is very uncomfortable and i had to purchase a memory foam cover for comfort.

Too Heavy

The bike is just too heavy to use the full suspension efficiently also the crankset is from Miranda which a very basic one but for beginners this bike is perfect and pretty useful , the tires aren't that great seeing the price of bike , the saddle is comfortable compared to other models in the same segment and the rear suspension works really well but can be only used for beginner and intermediate trails and jumps and the braking is hydraulic but even that's pretty basic

Брутално колело

Това колело е много добро за цената си! Не мога да повярвам че карам толкова добър и евтин продукт.

Спортни поздрави,

Добро, но не отлично

Бих препоръчал колелото, но не е най- доброто за цената си. След като го закупихме(за сина ми - дете на 12 год.) на следващия ден предната спирачка се разскърца и спирачната течност изтече. Закарахме го в магазина в Бургас и там разбирам, че сервиза не разполага с инструменти да го ремонтират. А това е ремонт за 10 минути. Чаках за това над седмица, като ми обясниха, че колелото е пътувало до Варна за ремонта - безумие.

Тотално препоръчвам продукта!

Колелото е страхотно! Не съм бил по доволен, за 909 лв. това колело попълва всички претенции. Аз тотално го препоръчвам! Препоръчвам да направите гумите tubelles защото колелото ще е по леко и по бързо. Единственото ми оплакване е че няма различни размери, а само малък.


Колелото е супер като начинаещи в dh, супер леко е и го препоръчвам за dh, trail и xc каране

Nadmíru splnilo očekávání

Hodnotím kolo z mého pohledu cyklisty začátečníka, který jezdí na vyjížďky asfalt - lehký terén a s kolem mám najeto cca 200 km. Obyčejné turistické sedlo jsem musel hned po první vyjížďce vyměnit. Pořídil jsem sedlo z Decathlonu ze série Selle Italia a dostavilo se prvotřídní pohodlíčko. “Jednokotouč” vpředu a “devítikvalt” vzadu není úplně ideální na dosažení maximální rychlosti na silnici. Kolo je pomalejší než jiné s převodníky 3x8 nebo podobnými. To je ale z negativ vše a vzhledem k ceně kola je sedlo to nejmenší co jsem si musel na kole přizpůsobit. Vzhledem k terénu, pro které je kolo určeno, je vlastně poznámka o menší rychlosti na silnicích zcestná. Takže negativa vlastně ani negativy nejsou. Zadní odpružení je velmi jednoduše nastavitelné podle váhy jezdce a společně s přední odpruženou vidlicí a zmíněným sedlem z kola tvoří úžasně pohodlný nástroj na krátké i dlouhé vyjížďky. Samozřejmě uvidím jakou vydrž budou mít jednotlivé komponenty, ale s kolem jako celkem jsem zatím maximálně spokojen. Za tuto cenu dostanete velmi pohodlné svezení.

Additional Product Information


Bike frame

  • 100% Aluminium 6061

Which is the right size?

Several sizes available: S: between 4'11" and 5'5" M: between 5'5" and 5'9" L: between 5'9" and 6' XL: between 6'1" and 6'7" If you are at the limit between 2 sizes: Choose the smaller size for easier steering (easier to handle) and comfort (straighter back). Choose the larger size for easier pedaling with a more stretched-out position (position more suited to performance).

Unisex frame

The ST 530 S MTB has a UNISEX frame. The ST 530's frame has been carefully designed down to the smallest detail, from the top tube's relatively pronounced slope, to the wide range of sizes (M: 5'5" to XL: 6'7"). The ST 530 S is not only lightweight and comfortable, but UNISEX as well. To make the most of the improved comfort, the women on the RockRider team recommend the 500 Women's Sports saddle, which is specially designed for the female form.

A word from the team

The ST 530 S mountain bike was fully designed and developed by our passionate MTB team at the B'Twin Village in France (Lille). A mountain bike that makes steering easier: more powerful and progressive hydraulic disc brakes, shocks, and a fork with 120 mm travel for riding over obstacles, a single chainring so you can very quickly adapt to changes in terrain, etc. MTB riders were involved at every stage of this bike's creation to make sure it works just right.

A light, comfortable frame

For less weight and more efficient pedaling, the RockRider ST 530 S frame is made from 6061 aluminum (only 6 lbs in size M without suspension). Its 120 mm rear shock uses a single-pivot system (more sensitive to small impacts, while remaining firm when encountering large impacts) and sealed bearings for a great lifespan.

120 mm front suspension

The hydraulic fork, with 120 mm travel, allows you to easily ride over more obstacles (roots, pebbles, stones, mud). The fork's built-in lockout system helps to prevent bobbing and loss of speed on faster terrain.

Rear suspension

This mountain bike has a RockRider U-Fit 120 mm spring shock absorber, specially adjusted for this frame. You can easily adjust it based on your weight, which provides you with a very good balance between sensitivity and performance.

Derailleur and drivetrain: a single chainring like the pros!

The single chainring is easy and efficient to use: 1 chainring and 9 speeds. Accelerate on the flats and easily tackle the climbs. With a single lever on the handlebar, you can change gears while hardly thinking! -ROCKRIDER FC ATB 500 single chainring (32T) -MICROSHIFT ADVENT rear derailleur with medium cage -MICROSHIFT ADVENT right shifter -MICROSHIFT H092 9-cog cassette (11-42 T) -KMC Z9 wide, sturdy chain

Handlebars, stem, grips

The adjustable stem brings the ST 530 S controls to your hands. The all-aluminum ROCKRIDER stem is 70 mm (size S), 80 mm (size M/L), or 90 mm (size XL) and can be raised to 5 adjustment intervals: + 0 mm, + 7.5 mm, + 15 mm, + 22.5 mm, + 30 mm. In detail: - 720 mm oversize ROCKRIDER SPORT aluminum handlebar - ROCKRIDER ergonomic grips for good grip and a comfortable feel.


The ST 530 S saddle is welded to prevent any saddle movement as you cycle. Because your comfort is our next priority after safety, we've added an exclusive RockRider Ergofit Evo saddle that is wider and hammock shaped. Easily adjust the height of your saddle with the 400 mm long, 31.4 mm diameter seat post.

Hydraulic disc brakes

No matter what conditions you ride in (dry/wet), the SHIMANO MT200 160 mm dual hydraulic disc brakes will come through for you, even in the mud. Hydraulic braking adds more power and progressive braking and requires less powerful use of the brake levers. The aluminum brake levers are easy to grip and precise.

27.5" wheels with double-walled rims and all-condition tires

The aluminum wheels are effective and sturdy: 27.5" diameter and double-walled rims. Their diameter is the perfect balance of comfort and performance. With their 28 spokes, they are lightweight, stiff, and durable. The wide, ROCKRIDER ALL CONDITIONS (30 TPI) 27.5" x 2.0 tires have side knobs designed for riding on all types of terrain (dry, wet, etc.). Tubeless Ready 23 mm rims: SCHRADER valves, TUBELESS rim tape, TUBELESS tires, and puncture-proof liquid to be added.

Platform pedals

The ST 530 S comes with RockRider Flat platform pedals with a wider pedaling surface and more pronounced dots for better grip on the pedals.

Easily transport and store your mountain bike

We added a quick release system for easily removing/reattaching the front wheel. Our advice: A bike rack is an easy way to transport your mountain bike without dirtying your car.


Your ST 530 S mountain bike comes with a bell, lights, wheel reflectors, and pedals. The frame is compatible with: -100 bottle cage (ref. 8049106) and 500 bottle cage (ref. 8358133) -Mountain bike mudguard set (ref. 8385291) -100 saddle bag (ref. 8347394) and 500 saddle bag (ref. 8354448)
