The motor on the rear wheel was co-developed with VISION for mountain biking: - a torque of 42Nm to overcome your first slopes - a wheel axle of 150x12mm to stand up to rough terrain - watertight bearings to withstand environmental conditions which can sometimes be tough. 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.
Tackle new obstacles (roots, rocks, gravel, etc.) with ease thanks to the 100 mm of travel in the Suntour XCT 30 fork, which gives you total comfort. This coil fork can be adjusted based on the rider's weight, starting at 45 kg, for more comfortable, enjoyable mountain bike rides.
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. The Tektro aluminium brake levers are easy to grip, lightweight, and precise.
So you feel safe on any terrain, and for traction suited to your motor, the E-ST100 women's electric MTB is equipped with B'Twin 27.5" tyres with a 2.2" width. Our testers particularly loved how versatile these tyres are. Mounted on wide rims, these tyres ensure grip, traction, and comfort

Understanding sizes and measurements
Height ranges are reported by the manufacturer. A matching range is a starting point, not a guarantee of fit. Your proportions and bike setup also matter.
Reach is the horizontal distance from the bottom bracket to the top of the head tube; stack is the vertical distance.
Positive values mean more reach or stack than the reference size; zero means the same measurement. Missing values are not estimated.
Enter your height to highlight matching ranges.
