    1. The story of the Rockrider E-ST500 electric mountain bike
      Entirely designed and developed in France at the B'Twin Village (Lille), this mountain bike is the fruit of the work of an expert team of passionate mountain bikers. Our Rockrider team has designed and tested this electric Rockrider E-ST500 bike with its test riders. All that's left to do is for us to wish you happy riding on this electric bike.
    2. How to choose your 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 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).
    3. A frame combining durability and pleasure to ride
      The frame of the Rockrider E-ST500 has been made from 6061 aluminium with hydroformed tubes. Why? So this electric mountain bike is robust and the battery fits snugly into the frame. The forged aluminium parts enable it to be compatible with the new 27.5+ tyre format (wider than the 27.5") whilst still being easy to handle. We've kept the frame geometry low to make sure that the bike stays comfortable to ride.
    4. A motor with 42Nm torque to climb any slope
      The motor on the rear wheel 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 environmental conditions which 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 already available in our 900 multi-purpose tool / bike multi-tool.
    5. 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 you go adventuring on rough terrain. A key lock is also installed if you want to protect your battery from theft.This is particularly useful if you park your electric mountain bike in the street.
    6. A simple, ergonomic control screen
      A discreet LCD control screen.Located just to the side of your left handlebar, choose between the 4 assistance modes without letting go of the grip: Deactivated, Economy, Standard, and Boost. You'll also find a host of useful information: -Chronometer -Speed -Distance covered -% battery level -Remaining battery in km -Active assistance mode -Reset And:the 0.5A USB port for charging your smartphone.
    7. 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. 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!
    8. 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 MTBers not using assistance who are a little fitter. Mode 2 - Standard: This is the most versatile mode. Climb any incline without tiring yourself out and avoiding using too much battery. Mode 3 - Boost: Overcome the insurmountable!Note:Using this mode for an extended time will reduce the length of your ride.
    9. Front hydraulic suspension to maintain control and soften 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.
    10. Single chainring drive train, 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 d cassette
