Our Rockrider mountain bike team has designed a battery that locks in place with a simple lever. Child's play! This locking system stops the battery getting shaken when you go adventuring on rough terrain. There is also a lock in case you want to stop your battery getting stolen. For example, if you park your bike in the street.
The motor on the rear wheel was co-developed with VISION for mountain biking:, - a torque of 42Nm to overcome any slope, - a 150x12mm hub to stand up to rough terrain, - and sealed bearings to withstand the weather, which can often be tough when mountain biking. What if you get a puncture? 8 Mm Allen key a needed to unscrew the wheel nuts. This tool is available in our 900 multi-purpose tool/bike multi-tool.
Calmly overcome obstacles (roots, rocks, gravel, etc.) thanks to the 100mm of travel in the Suntour XCR 30 fork. Its design, based on a mechanical spring, is reliable and easy to maintain. It features U-Fit (weight adjuster) technology so that you can easily adjust the stiffness, based to the rider's weight, using a dial.
The E-ST100 electric bike is equipped with a single chainring and ChainFlow 3D anti-slip technology to prevent the chain from derailing. A single shifter on the right handlebar makes it easy to shift between the 8 speeds. In detail:, - ChainFlow anti-derailment 33-tooth chainring, - MICROSHIFT M25 8-speed rear derailleur, - MICROSHIFT TS39 right shifter with indicator, - MICROSHIFT H081 8-cog cassette (11-34 teeth), - KMC Z7 chain
No matter the riding conditions (dry, muddy, wet), the Tektro TKD68 180 mm mechanical disc brakes at the front and rear provide powerful, progressive braking. Incompressible cable housing ensures a firm touch and perfect transmission of power from lever to disc.

So you feel safe on any terrain, and for traction suited to your motor, the E-ST100 MTB is equipped with exclusive Rockrider All Terrain Light (30 TPI) tyres with a wide 2.2-inch cross-section. Our test riders particularly liked these tyres for their good grip Mounted on wide rims, these tyres, and the rubber they are made from, provide great grip, traction, and comfort on any terrain.
Since your mountain bike rides will get longer and longer, it is important to sit comfortably. So our teams designed the exclusive ROCKRIDER Ergofit Evo saddle. Suitable for all hip sizes, the "hammock" shape is particularly good for sporty rides. The 31.6 mm aluminium seat post ensures compatibility with most adjustable and suspended saddles on the market.
