Our team designed this 27.5" electric mountain bike so you can get away and experience the fun of mountain bike touring in very hilly areas. Take on any terrain with this electric mountain bike thanks to its torque motor and extend your outings thanks to its 420Wh battery. The parts are designed for greater durability.
Not Available Now

We currently have limited capacity to build bikes in our warehouse. Due to this, we are limiting the number of bikes we sell per day and you might not be able to process your order at checkout. The count resets at 11pm every day so that would be the best time to try, although we do have a peak of attempts at this time so we can't guarantee a slot for everyone.

Technical Information

WHAT OUR TEAM HAS TO SAY

We created this E-ST 500 mountain bike at our B'TWIN VILLAGE (Lille, France) especially for mountain biking enthusiasts. We have designed and tested the bike E-ST 500, involving riders at every stage of the project. We want you to have nothing but fun when you go mountain biking.

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.

CHOOSING YOUR E-ST 500 MOUNTAIN BIKE SIZE

Several sizes available:
S: between 1.50m and 1.64m
M: between 1.65m and 1.74m
L: between 1.75m and 1.84m
XL: between 1.85 m and 2.00 m
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 EAMTB has been designed using 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 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 SLOPE

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.

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. For example, if you park your bike in the street.

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 4 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 range (in km)
-Active assistance mode
-Reset

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 mountain bikers 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:
Climb anything! Note: Using this mode for an extended time will reduce the length of your ride.

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

WIDE 27.5" DOUBLE-WALLED RIMS

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 Cougar 2.4" tyres for superior grip

So you feel safe on any terrain and for traction adapted to your motor, the E-ST500 mountain bike is equipped with Hutchinson Cougar 27.5" tyres 2.4" across. 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 any terrain.

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 OF THE HANDLEBARS

With its adjustable stem, the E-ST500 controls are close at hand. The all-aluminium ROCKRIDER stem is 70 mm (size S), 80 mm (size M/L), or 90 mm (size XL) and can be raised using 5 adjustment intervals: + 0mm, + 7.5mm, + 15mm, + 22.5mm, + 30mm.
In detail:
- oversize 720mm-wide aluminium frame for even more control
- soft touch ROCKRIDER SPORT grips for good grip and a comfortable feel

Saddle: Comfortable and sporty seat

Since your mountain bike rides will get longer and longer, it is important to have a suitable seat. Our teams have designed the exclusive ROCKRIDER Ergofit Evo saddle. It fits all hip sizes and has a curved shape that is particularly good for sport trail rides.
The 31.6 mm aluminium seat post ensures compatibility with most adjustable and suspended seat posts on the market.

PLATFORM PEDALS

The E-ST500 electric bike is supplied with ROCKRIDER 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
...

OUR ADVICE FOR YOUR FIRST RIDE

Tip no.1
When mountain biking, there is always the risk of a fall: don't forget to wear a helmet.
Tip no. 2
A puncture can happen at any time, so always remember to take a repair kit and an 8 mm Allen key for removing your rear motorised wheel.
Tip no.3
If you don't want to stop to drink, bring water in a bottle or water bladder to access it while riding.
