Specifications
Frameset
| Frame | 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 compatible with the new 27.5"+ tyre format (wider than the 27.5") in the rear, while remaining easy to manoeuvre. We've kept a frame geometry with short bases for easier steering. |
|---|---|
| Suspensions | 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. |
Wheels
| Wheels | 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. |

Brakes
| 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. |

| 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. |
| 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. |
E-System
| Battery | Our battery is equipped with battery cells from LG or Samsung, (LGC-MG1 or SDI), which are known for their high level of reliability and safety.Our battery supplier sources its minerals responsibly and sustainably, and is part of the "Responsible Minerals Initiative". - 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. |
|---|---|
| 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. |
