Review electric mountain bike Rockrider E ST 100 from Decathlon
The range of Decathlon electric mountain bikes is wide and it is often difficult to find the right product for your needs. That's why we decided to guide you by giving you our opinion following the test of the entry level of the brand, the Rockrider e st 100.
This assistance also allows you to activate the integrated lighting, track your battery level, speed, range and much more.
The Rockrider e st 100 braking system
The braking is ensured by quite powerful V-brakes, which allowed us to stop the electric bike in less than 3 m. In itself, this is not much considering the weight of the machine. The slightly wider tires than those of the Elops 500e probably explain this better result.
The battery in the carrier and the hub motor in the rear also improve rear braking efficiency. So in dry weather there is nothing to report. In the rain, the situation is even worse, because V-brakes are much less efficient than disc brakes.
In fact, they must first evacuate the water on the rim before they can brake effectively. So you need to go around the wheel before braking, which is a little more than 2 meters on a 28" wheel, as it is the case here. Another weakness of V-brakes on an electric bike is the fast wear.
Indeed, a bike with assistance reaches a cruising speed of 25 km/h faster, while it is heavier than a mechanical bike, which leads to a rapid aging of the brake pads. The manufacturer recommends replacement every 400 km in case of intensive use (heavy load, sandy road, etc.).
In the absence of a suspension and a suspended seatpost, comfort is spartan. Fortunately, the tires have enough air volume to absorb small shocks. Likewise, the seat is very welcoming. In the city, this is not too much of a problem overall, except on cobblestones, where it quickly becomes uncomfortable.
Weight and size of the Rockrider e st 100
For the Rockrider ST 100 several size are available :
- S: between 1.50 m and 1.64 m
- M : between 1.65 m and 1.74 m
- L : between 1.75 m and 1.84 m
- XL : between 1,85 m and 2,00 m
If you are at the border between 2 sizes, take the lower size, to privilege the phases of piloting (bike easier to handle) and comfort (back more straightened).
Take the superior size to privilege the phases of pedaling with a more lengthened position (position more adequate to the output). The weight of the Rockrider e st 100 is 22,5kg
The price
Previously at decathlon, the E-ST500 was their only electric mountain bike option available for less than 1000 euros, but now there is an even cheaper model, the Rockrider e st 100. It is offered at a price of 999 euros
To conclude
The Rockrider e st 100 is a very good electric bike for an entry level. It is of very good invoice and proposes services of quality. Notably due to the quality of manufacture but also to the equipment which composes it. This electric Rockrider 100 will be an excellent choice if you are only an amateur hiker. If not, look at the Rockrider E-ST 900 or even the Stilus Decathlon.
