Fork

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.

Groupset
Crank

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

Brakes

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.

Wheels
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.

Tires

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.

Electric Components
Motor

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.
