eBIG NINE 400 (EP6)

It tends to feel lively when you accelerate or surge. For MTB speed, tire choice and rolling resistance matter a lot, and that's baked into the score. What pushes it in this direction is relatively narrow MTB tires that roll quickly and a more budget-friendly drivetrain that focuses on value. On hardpack, the tire setup is biased toward rolling speed on firm ground.

How it climbs: 6.3/10. Within e-mountain bikes, it lands around the middle. It’s set up for steady spinning on climbs. Your easiest gear lands around 18.8 gear inches. Compared with similar bikes, this low gear is easier than about ~43% of them. “Gear inches” sounds nerdy, but it’s just a quick way to describe how easy your lowest gear is to turn uphill. Lower usually means easier. The motor support helps you keep rolling when the slope kicks up. You’ll be able to keep a steady spin even when it gets steep. 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 handling is rated 5/10. 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. Expect more grip and stability compared with basic bump-control setups. Not every manufacturer lists complete suspension numbers, so the explanation relies on the suspension layout and what’s normal for this category.

Comfort fit - a relaxed road posture that stays friendly on longer rides. Because handlebar height is roughly 8 mm lower than the saddle (very small drop), and how far you'll be stretched forward is about 596 mm (very long). Expect a lean angle around 22 degrees.

This bike's adjustability comes down to cockpit, routing, and seat setup: The cockpit is modular (separate stem and handlebar), so it is easier to adjust or swap fit parts, Cable routing is on the simpler side, which helps adjustability. At the same time, Seatpost details do not strongly point to a very locked-in or very flexible system. Net result: Adjustable. This mainly reflects how easy it is to adjust or swap key fit parts over time.

Ride comfort is 6.4/10 — on a real ride it feels comfortable. So it’s tagged Balanced overall. The posture is neutral (posture 5/10), which keeps it balanced — not overly aggressive, not overly relaxed.

This sits around the normal range for similar bikes. 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). On the spec estimate, the price is close to what we’d expect for a comparable build. Among comparable bikes, it sits around the middle on price (cheaper than about 47% of listings). Quick reference: €4.057 listed versus about €3.960 for a comparable build. Bottom line: it’s a normal deal — not amazing, not terrible.

This setup is aimed at fast trail riding on less extreme terrain. It has about 100 mm of suspension travel (how much it absorbs bumps), which suits smoother trails. The Hardtail setup supports this riding style.
