TECHNICAL INFORMATION

THE WOMEN'S ROCKRIDER PROJECT

This mountain bike was fully designed and developed at the B'Twin Village (Lille, France) and is the brainchild of an expert team of mountain bike enthusiasts.
The team has studied the features of female body shapes and used this to design and test the E.ST 500 women's bike, involving mountain bikers at every stage of the process.
Our aim is to make you want to jump onto your comfortable, easy-to-use mountain bike so that you enjoy every one of your rides.

IS ELECTRIC MOUNTAIN BIKING A SPORT?

Simply pedal to move 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.

HOW TO CHOOSE THE SIZE OF YOUR E.ST 500 MOUNTAIN BIKE

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) 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 make this electric mountain bike more robust.
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 MOTOR WITH 42NM TORQUE TO CLIMB ANY HILL!

The rear wheel motor is specially designed for mountain biking:
- a torque of 42Nm to overcome any slope
- a wheel axle of 150x12mm to resist the strains of rough terrain.
- and watertight bearings to resist weather conditions that can sometimes be tough.
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.

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 stops the battery getting shaken when you go adventuring on rough terrain.
There is also a lock in case you want to protect your battery from theft. For example, if you park your bike in 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:
-Time
-Speed
-Distance covered
-% battery level
-Remaining battery in km
-Active assistance mode
-Reset
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-ST500 EAMTB. You can easily 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 outings 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.

WALKING MODE

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 ON 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.

A SINGLE CHAINRING DRIVETRAIN THAT'S SIMPLE TO USE AND DESIGNED TO MEET THE DEMANDS OF ELECTRIC MOUNTAIN BIKING

To prevent the chain slipping, the E-ST500 electric bike is equipped with 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 chainguard
- 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:
- 23mm 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 mechanical disc brake calipers 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)
In detail:
- 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 31.6mm aluminium seat post ensures compatibility with most adjustable and suspended saddles on the market.

PLATFORM PEDALS

The E-ST500 electric bike is supplied with Flat platform pedals.
The pedal surface is wider and the dots more pronounced to better keep the foot on the pedal.

ACCESSORIES

Your E-ST500 mountain bike is supplied with a bell, lights, wheel reflectors and pedals.
The frame is compatible with:
- front and rear mudguards
- stand
- 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
...
