Tributary Sus Apex Eagle US

In mountain-bike land, this is a pedaling-speed measure - how fast it rolls when you're working for it. For assisted bikes, the rating focuses on the platform and setup rather than claiming a motor top-speed number. It trends this way because of a heavier build, wheel momentum that helps it carry speed between pedal strokes, typical trail-width tires, and a more budget-friendly drivetrain that focuses on value.

If your rides include hills, it rates 5.6/10 for climbing. Within e-mountain bikes, it lands around the middle. It’s set up for steady spinning on climbs. In numbers, the low gear is roughly 18.6 gear inches. Compared with similar bikes, this low gear is easier than about ~47% of them. Gear inches is basically “how easy is the easiest gear”. Lower numbers help you keep your legs spinning on steep bits. At about 22.4 kg, it’s a heavy build; the low gear matters even more when the slope kicks up. E-assist can take the sting out of steep ramps, especially at lower speeds. It’s set up so climbs feel controlled rather than a grind. Real-world feel depends on setup and size, and some details aren’t always listed, so this is best seen as a well-informed estimate.

Suspension rating is 6/10 — “Confident trail control”. This usually points to stronger bump control and steadier tracking when the surface gets choppy. Hardtail layout — suspension up front for control, rigid rear for a direct response. This level usually brings more reliable wheel tracking on rough patches and repeated hits.

Comfort fit - comfort-leaning without feeling sluggish. You get this posture because bars are around 23 mm lower than the saddle, which is a very small drop, and the forward stretch measures around 587 mm (very long). Plan for roughly 25 degrees of lean.

What affects adjustability on this bike: The cockpit is modular (separate stem and handlebar), so it is easier to adjust or swap fit parts, Less routing complexity makes swaps and adjustments more practical - Having a dropper increases how adaptable the bike feels in different situations. So we classify it as Adjustable.

Ride comfort is 6.6/10 — on a real ride it feels comfortable. So it’s tagged Firm overall. The posture is neutral (posture 5/10), which keeps it balanced — not overly aggressive, not overly relaxed.

For the spec, this is priced well into premium territory. 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). On the spec comparison, it sits roughly 39% above what similar builds typically cost. In its peer group, it’s one of the pricier listings, beating only about 24% of them. To anchor it: price €5.999 versus an estimated €4.307 for a similar build. Put simply: it’s priced more like a premium pick than a value buy.

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. Even though it’s tagged Trail, the setup fits Flow Trails better.
