What is Rockrider ?

The Rockrider range lists all the mountain bikes offered by the group. Indeed, since the year 2019, Decathlon has decided to divide the ranges under several brands. Formerly known as Btwin Rockrider, the brand has simplified everything so that the consumer can find it more easily. It is true that at the beginning all the bikes sold by the company appeared under the name Btwin, which made it difficult for the consumer to find his way around. Today, this debate is no longer, because the latter has taken things in hand and has made this important but necessary change. Future users can rest assured that even if the name changes, the quality of the products remains the same.

A new signature

As announced above, the Tricolor group has decided to make things clearer by allowing consumers to clearly distinguish the different ranges it offers. Thus, they can easily differentiate between mountain bikes, city bikes and road bikes.

In the past, for all the variants, we heard about Btwin. Even if their current names were already present but located just after it. So it was difficult to find your way around. Nevertheless, today this name is still present in one of the ranges offered by the company. It is certainly intended to reassure consumers. This name is synonymous with quality, aesthetics and affordable price.

The different ranges offered by Decathlon

As we have already mentioned in the first part, Decathlon offers consumers a wide range of products that meet the majority of needs in terms of cycling mobility. Indeed, here are the 4 ranges that the group offers:

  • The Rockrider range : Mountain bike
  • The Riverside range : Cross-country bike
  • The Triban range : Road bike
  • The Elops range : City bike
  • The name Rockrider is thus assimilated to the range of bicycles known as all-terrain (cross-country) proposed by Decathlon. They exist in both classic and electric versions.

    Presentation of the ST 100 Rockrider bike

    The Rockrider ST 100 is the first entry-level bike signed Rockrider and no longer Btwin. It comes for the moment between the Rockrider 340 and the Rockrider 520. This small mountain bike is entirely designed and developed in France, in Lille more precisely. If you are a mountain biker looking for comfort, efficiency, and sturdiness, then the ST 100 Rockrider is made for you. It will allow you to be efficient and for a relatively reasonable price.

    Technical specifications of the Rockrider ST 100

    Before buying the Rockrider ST 100 bike, it is important to learn more about its features.

    Rockrider ST 100: for whom ?

    It is studied in its smallest details. With a very pronounced top tube slope, also called sloping, the Rockrider offers a very wide size range. Its CGF frame is not only light and comfortable, it is also mixed. In fact, the Rockrider ST 100 is available with the same frame in a women’s version. The saddle is adapted, the handlebars are narrower, the stem shorter, the fork with a softer spring, and finally, the brake levers closer together.

    If, however, as a woman you choose the men’s model, and you want to enjoy even more comfort, we recommend buying the women’s sport saddle 500. Specially adapted to the female morphology.

    Available in several sizes

    For the Rockrider ST 100 bike, there are several sizes available:

  • If you hesitate between two sizes, we advise you to choose the larger size. In order to adjust the ST 100 Rockrider bike to your height and body type, it is recommended that you touch the ground with the tip of your feet when you are sitting on the saddle. To adjust the saddle, your knee should be slightly bent with your foot on the pedal in the down position.

    What could be better in the cycling world than hydraulic disc brakes? Indeed, you will be able to count on a powerful and progressive braking thanks to the two V-Brake pads. These brakes will respond to any weather conditions or type of ground you ride on. You will be able to operate them in a very simple way thanks to the aluminium brake levers present in front of the handlebars. Only two fingers are needed to brake.

    We advise you to check the wear of the skates once a year. If the streaks disappear, do not hesitate to make an appointment at your shop.

    Purchase aids

    Well, even if the purchase of an electric bike can sometimes be a real obstacle course, some elements can convince you to take the plunge. Indeed, don’t be afraid of the bill, on the contrary. As for electric cars, the State, as well as the regions and the municipalities, have set up subsidies to facilitate the acquisition of these new means of transport. Some of them can even be cumulated and thus make the basic investment less important for the consumer. To give you an idea, we can give you the following figures:

  • National aid: equal to 20% of the purchase price including tax or 200€ maximum
  • Regional aid: variable according to the regions, between 150€ and 600€.
  • Communal aid: depends on the communes. In Paris, for the purchase of an electric bike you can receive up to 400€.
  • Thus, the final amount you will have to pay for your electric bicycle will be significantly reduced. Nevertheless, these data are for information purposes only. It is therefore advisable to find out more about the eligibility details and access conditions.

    To find out if you can benefit from these subsidies, we advise you to get in touch with your local authorities, or simply to visit the government website.
