eBIG.NINE 400

In mountain-bike land, this is a pedaling-speed measure - how fast it rolls when you're working for it. Compared with more speed-first builds, this build is shaped by relatively narrow MTB tires that roll quickly, wheel momentum that helps it carry speed between pedal strokes, and a more budget-friendly drivetrain that focuses on value. On hardpack, the tire setup is biased toward rolling speed on firm ground.

Uphill performance score: 5.9/10. Within e-mountain bikes, it lands around the middle. On climbs, the lowest gear feels easy. In numbers, the low gear is roughly 19.3 gear inches. Compared with similar bikes, this low gear is easier than about ~34% of them. Think of “gear inches” like a difficulty score for your easiest gear: lower = more spin-friendly on climbs. The motor support helps you keep rolling when the slope kicks up. It’s set up so climbs feel controlled rather than a grind. 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.

Suspension performance: 5/10. It’s grouped into “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. On roots and rocks, it should keep the bike calmer through repeated impacts. 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. Because you get a very small drop: roughly 25 mm from saddle to bar, plus about 605 mm of stretch forward (very long). Estimated lean is about 25 degrees.

In E-bikeMountain / Crosscountry, What affects adjustability on this bike: Because the bar and stem are separate, changing reach or bar shape is usually straightforward, The front-end is easier to work on, supporting fit tweaks over time. Plus, A standard round seatpost size gives you many options for fit and replacements. So we classify it as Adjustable.

Comfort comes out to 6.4/10, which usually translates to a comfortable ride. That’s why it’s labeled Balanced. The posture is neutral (posture 5/10), 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 74% of listings. Quick reference: €2.840 listed versus about €3.888 for a comparable build. 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 100 mm of suspension travel (how much it absorbs bumps), which suits smoother trails. Suspension type (Hardtail) fits this kind of terrain.
