This MTB speed measure favors setups that roll efficiently without sacrificing too much traction. If it's an e-bike, think of this as a bike speed feel score: how the parts and setup help the bike move fast. It ends up here thanks to a heavier build, a lighter-feeling build that helps when you're pedaling for speed, typical trail-width tires, and a more budget-friendly drivetrain that focuses on value.

If your rides include hills, it rates 7.8/10 for climbing. Within e-mountain bikes, this comes out above average. It’s set up for smooth spinning on steeper climbs. In numbers, the low gear is roughly 16.9 gear inches. In its peer group, it lands around the easier ~91% for low-gear climbing. Think of “gear inches” like a difficulty score for your easiest gear: lower = more spin-friendly on climbs. With roughly 18.9 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. 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.

Overall suspension support: 8/10 (“High-impact ready”). It typically supports higher-speed rough sections where impacts stack up quickly. Both ends absorb impacts, improving how consistently the tires can follow rough terrain. This level is meant to keep the bike composed when hits are bigger and frequent. Suspension travel is the amount of movement available over bumps — here it’s about 160 mm up front and 150 mm at the rear. More travel usually means more room to absorb bigger hits.

Sporty fit - you'll lean forward more and feel ready to push the pace. You get this posture because bar height comes out ~87 mm below the saddle (large), with about 652 mm of forward reach - a extreme stretch. Plan for roughly 35 degrees of lean.

In E-bikeMountain, That is why we tag it Moderately Adjustable. This rating is mainly driven by the parts that affect adjustability: Because the bar and stem are separate, changing reach or bar shape is usually straightforward, Less routing complexity makes swaps and adjustments more practical; From the seatpost text provided, there are no strong constraints or bonuses.

Comfort comes out to 8.3/10, which usually translates to a plush ride. It’s tagged Balanced for Enduro — it feels plush overall, but it’s on the firmer end compared with the plushest Enduro builds. The posture is forward, attacking (posture 8/10, torso ~35°), which loads the front wheel, which feels great for control but a bit more direct through the bars.

For the spec, this feels competitively priced. 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. In its peer group, it tends to be better-priced than many, beating about 73% of listings. Quick reference: €5.879 listed versus about €5.983 for a comparable build. Some manufacturer details aren’t fully published, so use this as a helpful direction rather than a final verdict. Put simply: it’s competitively priced for what you get.

This bike is built for rougher, more technical trails where control matters. 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.
