4060 Z ST NX USA

For MTB speed, tire choice and rolling resistance matter a lot, and that's baked into the score. Even on an e-bike, the rating is driven by the bike's setup - tires, weight, and build choices - rather than the motor alone. A few practical factors stand out: typical trail-width tires, wheel momentum that helps it carry speed between pedal strokes, and a more budget-friendly drivetrain that focuses on value.

Climbing rating: 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. On the ‘easier low gear’ scale, it sits around ~34% versus similar bikes. Think of “gear inches” like a difficulty score for your easiest gear: lower = more spin-friendly on climbs. E-assist can take the sting out of steep ramps, especially at lower speeds. Good for keeping cadence steady on climbs without overcooking it. 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.

Overall suspension support: 8/10 (“High-impact ready”). This level is aimed at repeated impacts and rougher terrain, keeping the bike more settled at speed. Both ends absorb impacts, improving how consistently the tires can follow rough terrain. It’s designed to stay composed when impacts come quickly one after another, especially at higher speeds.

Sporty fit - a performance-leaning position that encourages speed. Because there's about 51 mm of drop to the bars (moderate), with roughly 647 mm of forward stretch to the bar (extreme). Estimated lean is about 29 degrees. Front-end spacers are estimated around 14 mm.

Overall, it is Moderately Adjustable. Main reasons for the fit flexibility result: Separate bar and stem components keep fit changes practical, 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. Put simply, it describes how practical it is to reconfigure your position later.

Comfort comes out to 8.3/10, which usually translates to a very smooth ride. It’s tagged Balanced for Enduro — it feels very smooth overall, but it’s on the firmer end compared with the plushest Enduro builds. The posture is forward, attacking (posture 7/10), which loads the front wheel, which feels great for control but a bit more direct through the bars.

Nothing screams bargain or rip-off here. 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). Based on the spec estimate, it’s about 10% above the typical level for similar builds. Among comparable bikes, it sits around the middle on price (cheaper than about 57% of listings). Quick reference: €7.499 listed versus about €6.807 for a comparable build. Overall, it sits in the expected range for the category.

This bike is built for rougher, more technical trails where control matters. It has about 160 mm of suspension travel (how much it absorbs bumps), which helps on rough, technical trails. The Full setup supports this riding style.
