27.5 Inch Electric Mountain Bike E-ST 520

For MTB speed, tire choice and rolling resistance matter a lot, and that's baked into the score. Key drivers include a heavier build, typical trail-width tires, and a capable drivetrain that supports steady speed. Overall, those details affect how quickly it accelerates and how easily it maintains pace. On smoother terrain, the tire setup is biased toward rolling speed on firm ground.

Overall on climbs: 6.3/10. Within e-mountain bikes, it ranks around the middle. On climbs, the lowest gear feels very easy. In numbers, the low gear is roughly 16.9 gear inches. On the ‘easier low gear’ scale, it sits around ~91% versus similar bikes. Gear inches is basically “how easy is the easiest gear”. Lower numbers help you keep your legs spinning on steep bits. Weight is around 22.5 kg — on steep, slow climbs that extra mass becomes more noticeable. E-assist can take the sting out of steep ramps, especially at lower speeds. This kind of low gear helps you stay smooth on long or steep climbs. Specs can vary by size and build, and some manufacturer details aren’t always published, so treat this as a strong guide rather than a guarantee.

Suspension handling is rated 6/10. It matches “Confident trail control”. This usually points to stronger bump control and steadier tracking when the surface gets choppy. It’s a common compromise: calmer front wheel, efficient rear end. It should keep the bike more controlled on mixed surfaces, especially through repeated small-to-medium impacts.

Balanced fit - a versatile position for long rides and faster efforts. Based on full geometry data.

What drives the fit flexibility here: Standard cockpit parts make it simpler to fine-tune your position over time, The front-end is easier to work on, supporting fit tweaks over time, and From the seatpost text provided, there are no strong constraints or bonuses. So we classify it as Adjustable.

Ride comfort is 6.6/10 — on a real ride it feels comfortable. So it’s tagged Race-Stiff overall. The posture is neutral (posture 5/10), which gives a steady, predictable feel without pushing you too far forward.

For what you get, the price looks very hard to beat. The value score is 1–10. Higher means better value for money; lower means the price is high for what you get. Uses MSRP as a baseline; real-world prices can be lower (discounts can change the value). Based on the parts list, it’s roughly 36% cheaper than what similar builds typically cost. Against similar bikes of the same type and age, it’s usually on the cheaper side, beating about 99% of listings. Quick reference: €2.121 listed versus about €3.292 for a comparable build. Some manufacturer details aren’t fully published, so use this as a helpful direction rather than a final verdict. Bottom line: you’re getting a lot of bike for the money compared with typical options.

This bike is best for smoother trails where speed and efficiency matter. It has about 120 mm of suspension travel (how much it absorbs bumps), which suits smoother trails. Suspension type (Hardtail) fits this kind of terrain.
