27.5″+ Electric Hardtail MTB Bike E-ST 900

This MTB speed measure favors setups that roll efficiently without sacrificing too much traction. Compared with comfort-biased setups, this build is shaped by a heavier build, typical trail-width tires, and a basic drivetrain spec that prioritizes practicality over outright performance. On smoother terrain, the tire setup is biased toward rolling speed on firm ground.

On steep roads, it comes in at 6.4/10. Within e-mountain bikes, it sits around the middle. On climbs, the lowest gear feels very easy. That lowest gear comes out around 16.9 gear inches. Compared with similar bikes, this low gear is easier than about ~91% of them. Gear inches is basically “how easy is the easiest gear”. Lower numbers help you keep your legs spinning on steep bits. With roughly 22.0 kg under you, you’ll feel the weight on longer climbs even with a decent low gear. The motor support helps you keep rolling when the slope kicks up. This kind of low gear helps you stay smooth on long or steep climbs. Build kits can differ by size and spec level, and not every detail is published by every brand, so use this as a practical guideline.

On the suspension scale, it comes in at 5/10 — “Confident trail control”. That typically means noticeably better bump absorption and more consistent tracking on rougher sections. The fork does the smoothing; the rear stays straightforward and efficient. This level helps keep traction when the surface is uneven and choppy. This level usually brings more reliable wheel tracking on rough patches and repeated hits.

Balanced fit - a versatile position for long rides and faster efforts. Mostly geometry-based, with a small category-based estimate.

This bike's adjustability comes down to cockpit, routing, and seat setup: A modular front-end gives more freedom to change stem length or bar width, and A more service-friendly routing setup makes changes easier. Overall, it falls into Adjustable.

Comfort comes out to 6.5/10, which usually translates to a nicely smooth ride. That’s why it’s labeled Comfortable. The posture is neutral (posture 6/10), which gives a steady, predictable feel without pushing you too far forward.

This is the kind of deal people usually notice quickly. Value is scored 1–10: higher is better value, lower means you’re paying more than similar bikes. Uses MSRP as a baseline; real-world prices can be lower (discounts can change the value). Based on the parts list, it’s roughly 27% cheaper than what similar builds typically cost. In its peer group, it tends to be better-priced than many, beating about 73% of listings. To anchor it: price €2.496 versus an estimated €3.410 for a similar build. Some manufacturer details aren’t fully published, so use this as a helpful direction rather than a final verdict. Put simply: this is strong value for what’s included.

This bike is best for smoother trails where speed and efficiency matter. Suspension travel details aren’t available here, so the label follows the category and the rest of the setup. Overall, the setup matches this surface range well.
