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.
The motor on the rear wheel was co-developed with VISION for mountain biking: - a torque of 42Nm to overcome your first slopes - a wheel axle of 150x12mm to stand up to rough terrain - watertight bearings to withstand environmental conditions which can sometimes be tough. 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.
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.
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
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.
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 specific PRESTA valve and tyre sealant.
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 grip on the ground. Mounted on wide rims, these tyres ensure grip, traction, and comfort on any terrain.
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.

Understanding sizes and measurements
Height ranges are reported by the manufacturer. A matching range is a starting point, not a guarantee of fit. Your proportions and bike setup also matter.
Reach is the horizontal distance from the bottom bracket to the top of the head tube; stack is the vertical distance.
Positive values mean more reach or stack than the reference size; zero means the same measurement. Missing values are not estimated.

Geometry not published
The manufacturer lists these sizes without frame measurements, so there is no drawing or geometry table.
