Root Miller Plus 4

It's tuned for reliability and control rather than maximum speed. On an MTB, the speed score centers on rolling efficiency when you're pedaling, especially on easier terrain. The strongest influences are a heavier build, typical trail-width tires, and a high-end drivetrain that tends to feel crisp under load. When conditions are smooth, the bike's setup can make speed feel easier - or more costly.

On steep roads, it comes in at 5.4/10. Within e-mountain bikes, it sits around the middle. It has an easy low gear for steady climbing. Your easiest gear lands around 19.1 gear inches. On the ‘easier low gear’ scale, it sits around ~40% versus similar bikes. Think of “gear inches” like a difficulty score for your easiest gear: lower = more spin-friendly on climbs. With roughly 22.6 kg under you, you’ll feel the weight on longer climbs even with a decent low gear. Being an e-bike helps on climbs because the assist adds steady push when you need it. This kind of low gear helps you stay smooth on long or steep climbs. Different builds can shift the feel a bit, and some manufacturer specs aren’t always publicly listed, so consider this a helpful direction.

Suspension capability comes out at 7/10. Bucket: “High-impact ready”. It’s designed to stay composed through rough sections and repeated hits. Suspension at both ends helps keep wheel tracking steadier when the surface gets rough. Travel is the available suspension movement when the wheel hits an impact. Here it’s about 150 mm up front and 150 mm at the rear. Bigger travel numbers typically feel calmer when the surface gets rough. On rough trails, this level aims to keep the bike settled under braking and cornering through repeated hits.

Balanced fit - a middle ground between comfort and speed. That's driven by the bar sits about 43 mm below the saddle (a moderate drop), and you'll be stretched forward about 622 mm in total (very long). Expect a lean angle around 28 degrees. Estimated spacers: ~15 mm.

In E-bikeMountain, Fit flexibility summary: A modular front-end gives more freedom to change stem length or bar width, Cable routing is on the simpler side, which helps adjustability, Seatpost details do not strongly point to a very locked-in or very flexible system. Plus, A dropper makes it easier to shift between climbing and descending positions. Net result: Adjustable. In practice, it is about how easy fit changes are with normal parts and service work.

Ride comfort is 8.0/10 — on a real ride it feels very smooth. That’s the reason it lands as Race-Stiff. The posture is forward, attacking (posture 7/10), which puts you in an attack stance, which can feel more intense on long, rough descents.

This looks like a typical market price for the spec. 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 spec estimate, it’s about 12% above the typical level for similar builds. Among comparable bikes, it sits around the middle on price (cheaper than about 54% of listings). To anchor it: price €8.701 versus an estimated €7.796 for a similar build. Bottom line: it’s a normal deal — not amazing, not terrible.

This setup suits steeper, rockier terrain and harder hits. It has about 150 mm of suspension travel (how much it absorbs bumps), which helps on rough, technical trails. Suspension type (Full) fits this kind of terrain.
