For This Bike
| Fork | Calmly overcome new obstacles (roots, rocks, gravel, etc.) thanks to the 120mm of travel in the Suntour XCR hydraulic 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. Travel: 120mm |
|---|---|
| Saddle | Since your mountain bike rides will get longer and longer, it is important to have a suitable seat. So our teams 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 tube ensures compatibility with most dropper and suspension seat posts on the market. |
| Crank | The E-ST500 electric bike is equipped with a single chainring and SRAM X-SYNC anti-drop technology to prevent chain drops. A single shifter on the right handlebar makes it easy to shift between the 9 speeds. In detail:, - SRAM X-Sync 32-tooth chainring, - Shimano Altus M2000 9-speed rear derailleur, - Shimano Altus M2000 shifter with gear indicator, - Shimano Altus 9-cog 11-36 cassette, - KMC X9 chain |
|---|---|
| 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. Type: Mechanical Disc |
| Rims | These wheels were specially designed for this mountain bike:, - 19 mm rim with 28 spokes at the front, - 23 mm rim (distance between flanges) with 36 oversize spokes at the back for more sturdiness and a good hold on wide tyres up to 2.5". - Cone hub with bearings (easy to maintain) at the front, - Sealed motor bearings at the rear, - TUBELESS compatible at the rear: you'll need rim tape, a TUBELESS tyre, a PRESTA valve and tyre sealant |
|---|---|
| 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" x 2.4" tyres. Our test riders particularly liked these tyres for their good grip. Mounted on wide rims, these tyres ensure grip, traction and comfort on any terrain. |
| 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. |
|---|---|
| Battery | 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 stop your battery getting stolen. For example, if you park your bike in the street. |
