IS MOUNTAIN BIKING WITH AN ELECTRIC BIKE A SPORT?: You have to pedal to go forward!. The electrical assistance supplements your pedalling to help you overcome obstacles. You can enjoy your mountain bike rides for longer, and even out the abilities within a group.
Some women even find that the electric mountain bike is what gets them back in the saddle!. The rear motor, with its cadence sensor, stops the electrical assistance when you stop pedalling. The walking mode offsets the mountain bike's weight when you need to walk your bike.
AN ELECTRIC MOUNTAIN BIKE FOR WOMEN: Our teams performed a postural study on a mountain bike to ensure that women are comfy in the saddle: The "women comfort" saddle on the Women's E.ST 100 is ergonomic: hollowed in the centre to prevent chafing. The 60 mm stem is shorter, as women's torsos are shorter. This prevents an overly horizontal position which may cause back or neck pain.
The position can be raised by placing an adapter under the stem. The fork can be adjusted to your weight. The 620 mm handlebar is narrower.
WHAT SIZE MOUNTAIN BIKE TO CHOOSE?: Several sizes available: S: between 1.50m and 1.64m.
M: between 1.65m and 1.74m.
L: between 1.75m and 1.84m.
If you are on the limit between 2 sizes: Choose the smaller size for easier steering (easier to handle), comfort (straighter back) and an easier step-through.
A FRAME FOR STURDINESS AND FUN: The frame of the Rockrider E-ST100 women's bike has been made from 6061 aluminium with hydroformed tubes. Why? The battery sits snugly on the frame to improve the robustness of this electric mountain bike.
The forged aluminium parts make it compatible with both 2.2" tyres and 27.5" wheels while still keeping the bike easy to handle. We've kept the frame geometry low to make sure that the bike stays comfortable to ride.
A MOTOR WITH 42NM TORQUE TO CLIMB ANY HILL!: The rear wheel motor is specially designed for mountain biking: - torque of 42 Nm/380 Wh to help you get past obstacles.
- a 150 x 12 mm wheel axle to deal with rugged terrain. - and sealed bearings to withstand the weather, which can often be tough when mountain biking. What if you get a puncture? An 8mm Allen key is all you need to unscrew the wheel nuts.
This tool is available in our 900 multi-purpose tool/bike multi-tool.
A BATTERY WITH LG CELLS: Our battery is equipped with LG, LGC-MG1 cells, renowned for their high level of reliability and safety. It can be recharged in 6 hours.
A battery that's easy to lock: Our Rockrider mountain bike team has designed a battery that locks in place with a simple lever. Child's play!. This locking system prevents any vibrations to the battery when riding on rough terrain.
There is also a lock in case you want to stop your battery getting stolen, such as when parking your bike on the street.
CADENCE SENSOR: The cadence sensor on the E.ST 100 women's bike tailors the electrical assistance to your pedalling. The faster the cadence, the more electrical assistance you get.
To slow down, reduce your cadence. When you stop pedalling, the bike returns to acting like a normal bike.
A simple, ergonomic control screen: A discreet LCD control screen.
The screen is right next to your left grip so you don't have to let go of the handlebar to choose from the 3 assistance modes available: (Deactivated), Economy, Standard, and Boost.
You'll also find a host of useful information: -Stopwatch. -Current speed.
-Average speed. -Maximum speed. -Distance covered.
-Total distance. -Battery level. -Remaining battery life (in km).
-Pedestrian assistance mode. -Reset.
VERY PRACTICAL PEDESTRIAN MODE!: When you want to push your bike, activate the pedestrian mode to trigger a low level of electrical assistance that compensates for the bike's weight.
This allows you to easily push your bike without it being too heavy.
Practical: walk right next to it!.
SWITCH GEARS EASILY: The E-ST100 electric bike is equipped with a single chainring and ChainFlow 3D anti-slip technology to prevent the chain from derailing.
An end to confusion: simply change between the 8 speeds using the single shifter on the right handlebar.
In detail: - ChainFlow 32-tooth chainring. - MICROSHIFT M25 8-speed rear derailleur.
- MICROSHIFT TS39 8-speed right shifter with indicator. - MICROSHIFT H081 8-cog cassette (11-34 teeth). - KMC Z7 chain.
RIDE ALL YEAR ROUND: The exclusive ROCKRIDER ALL TERRAIN LIGHT (30 TPI) 27.5" x 2.2 tyres have durable rubber and side knobs designed for riding on all types of terrain (dry, wet, etc).
FRONT SUSPENSION TO MAINTAIN CONTROL AND ABSORB BUMPS FROM ROUGH TERRAIN: 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.
BATTERY RANGE: The E.ST100 women's mountain bike has a battery range of 100 km in eco mode on flat terrain and 44 km on hilly mountain biking terrain. The battery can be recharged in 6 hours.
180mm double disc brakes: GET A GRIP ON YOUR BRAKING: No matter the conditions you ride in (dry, muddy, wet), the 180 mm mechanical disc brake callipers on the front and rear provide powerful, progressive braking.
These oversized 180mm diameter discs provide even more power. The Tektro aluminium brake levers are easy to grip, lightweight, and precise.
BTWIN 2.2" MIXED TERRAIN TYRES: 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.
