IS ELECTRIC MOUNTAIN BIKING A SPORT?
You have to pedal to go forward!
The electric assistance boosts your pedalling by 150% so you can easily get past obstacles and keep going for longer on your mountain bike rides, smoothing out the levels within a group.
The motor stops its electrical assistance when you stop pedalling.
The walking mode compensates for the weight of the bike when you need to put your feet down.
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 500 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
CHOOSING YOUR E-ST 500 MOUNTAIN BIKE SIZE
Several sizes available:
S: between 1.50m and 1.64m
M: between 1.65 m and 1.74 m
L: between 1.75 m and 1.84 m
If you are between 2 sizes:
Choose the smaller size for easier steering (easier to handle) and comfort (straighter back).
Choose the larger size for easier pedalling with a more stretched-out position (position more suited to performance).
A FRAME FOR STURDINESS AND FUN
The frame of the Rockrider E-ST500 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 both compatible with the new 2.4 x 27.5+ tyre format (wider than the 27.5") and easy to manoeuvre.
We've kept the frame geometry low to make sure that the bike stays comfortable to ride.
A 42NM MOTOR TO CLIMB YOUR FIRST SLOPES
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.
A BATTERY WITH LG CELLS
Our battery is equipped with LG, LGC-MG1 cells, renowned for their high level of reliability and safety.
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 the battery vibrating 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.
A simple, ergonomic control screen
There is an LCD screen just next to your left grip. You don't need to let go of your handlebar to choose between the 4 assistance modes: Disabled, Economic, Standard and Boost + walking mode.
You'll also find a host of useful information:
-% battery level
-Remaining battery in km
-Active assistance mode
And: the 0.5A USB port for charging your smartphone.
A torque sensor for natural pedalling, even on difficult terrain
Wondering how to conveniently control your speed, particularly on technically difficult terrain?
Our Rockrider mountain bike team has included a torque sensor on the bottom bracket of the E-ST 500. This will allow you to control the level of electrical assistance in the simplest way possible: by pedalling!
Press harder on the pedal, and you'll accelerate; press less, and you'll slow down!
4 assistance modes for any situation
Mode 0 - Deactivated
The battery is not used.
Mode 1 - Economy:
Extend your rides by preserving the battery. Ideal for keeping up with other riders without assistance who are in better shape.
Mode 2 - Standard:
This is the most versatile mode. Climb any slope without getting too tired and without using too much power.
Mode 3 - Boost:
Overcome the insurmountable! Note: Using this mode for an extended time will reduce the length of your ride.
To make up for the bike's weight, you can use the walking mode to easily push the bike along.
FRONT HYDRAULIC SUSPENSION TO MAINTAIN CONTROL AND ABSORB BUMPS FROM ROUGH TERRAIN
Calmly overcome new obstacles (roots, rocks, gravel, etc.) thanks to the 120mm of travel in the Suntour XCR fork.
Our Rockrider mountain bike team worked with Suntour to design a superior lubrication and wiper seal for this electrically-assisted mountain bike. This ensures the fork stays sensitive over time.
SINGLE CHAINRING DRIVETRAIN, SIMPLE TO USE AND DESIGNED TO MEET THE DEMANDS OF ELECTRIC MOUNTAIN BIKING
To prevent the chain coming off, the E-ST500 electric bike has a single SRAM NX chainguard with X-Sync technology. Made from steel for greater durability.
An end to confusion: simply change between the 9 speeds using the single shifter on the right handlebar.
In detail: - Sram X-Sync 32-tooth BCD 94 steel chainring
- Shimano Altus M2000 9-speed rear derailleur
- Shimano Altus M2000 shifter
- KMC x9 chain
- 9-speed 11-36 tooth cassette
27.5" WIDE DOUBLE-WALLED WHEELS
These aero trail wheels have been specially designed for mountain biking:
- 23 mm rims for improved durability and good grip on wide tyres.
- a rear wheel with 36 oversized spokes to resist the torque of the motor.
HUTCHINSON TAIPAN 2.4" TYRES FOR BETTER GRIP
So you feel safe on any terrain and for traction adapted to your motor, the E-ST500 mountain bike is equipped with Hutchinson 27.5" x 2.4 tyres (TAIPAN).
Our test riders particularly liked these tyres for their grip on the ground. Mounted on wide rims, these tyres ensure grip, traction, and comfort on all terrain and in any weather conditions.
180mm double disc brakes: GET A GRIP ON YOUR BRAKING
No matter the conditions you ride in, (dry, muddy, wet), the Hayes MX5 cable-operated disc brakes on the front and rear provide powerful, progressive braking. Oversized 180mm diameter discs provide even more power.
The Tektro aluminium brake levers are easy to grip, lightweight, and precise.
HANDLEBAR, STEM, GRIPS: Take control with ergonomics designed for women!
With its adjustable stem, the E-ST500 controls are close at hand. The 60mm B'Twin stem is entirely made from aluminium and designed for women's bodies as it can be raised to 5 marked levels: + 0 mm, + 7.5 mm, + 15 mm, + 22.5 mm, + 30 mm (turn the spacer upside down)
- 680mm-wide oversized aluminium handlebars to adapt to the width of women's shoulders.
- Soft touch B'Twin sport grips for good grip and a comfortable feel
Saddle A comfortable sporty seat, specially designed for women
Since your mountain bike rides will get longer and longer, it is important to have a suitable seat.
This is why our teams have designed the exclusive, comfortable "Women Comfort Plus" saddle. Adapted to all hip widths, its profile has been specially designed for women.
The 31.6 mm aluminium seat post ensures compatibility with most adjustable and suspended seat posts on the market.
The bike comes with 520 Grip MTB platform pedals (ref. 8487130) with a wider pedalling surface and more pronounced dots for better grip on the pedal.However, if you are looking for improved performance when pedalling and better control of the bike when cycling, we recommend replacing them with clipless pedals with platforms or wide aluminium platform pedals.
Your E-ST500 mountain bike is supplied with a bell, lights, wheel reflectors and pedals.
The frame is compatible with:
- front and rear mudguards
- bottle cage (on the horizontal tube)
- saddle pouch
- rear pannier rack (fixed onto the seat stays or special mounts for wide bikes, 150mm gap for the rear wheel)
- child seat
OUR ADVICE FOR YOUR FIRST RIDES
When mountain biking, there's always the risk of a fall: remember to wear a helmet!
For your first rides, play around with the different electrical assistance modes when you're still close to home.
Remember to take a repair kit and 8 mm Allen key for removing your motorised rear wheel.
If you don't want to stop to have a drink, remember to take water in a bottle or hydration backpack for easy access
