STEREO HYBRID ONE77 HPC, AT

For mountain bikes, this is about pedaling and rolling speed on firm trails or hardpack, not downhill confidence. Pedal assist doesn't erase physics; tire drag and weight still influence pace, and this score reflects that. What pushes it in this direction is a heavier build, typical trail-width tires, and a high-end drivetrain that tends to feel crisp under load.

Climbing rating: 5.2/10. Within e-mountain bikes, it sits around the middle. On climbs, the lowest gear feels easy. The easiest gear works out to about 19.1 gear inches. Compared with similar bikes, this low gear is easier than about ~40% of them. Gear inches is basically “how easy is the easiest gear”. Lower numbers help you keep your legs spinning on steep bits. With roughly 24.1 kg under you, you’ll feel the weight on longer climbs even with a decent low gear. 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. Specs can vary by size and build, and some manufacturer details aren’t always published, so treat this as a strong guide rather than a guarantee.

On the suspension scale, it comes in at 9/10 — “Extreme rough-terrain ready”. That’s built for big impacts and very rough terrain, where keeping wheels tracking matters most. Full suspension means both ends can absorb impacts, helping the wheels track rough ground more consistently. Travel is how far the suspension can move when it hits a bump — here it’s about 172 mm at the rear. As a rule of thumb, more travel gives more headroom for bigger impacts. This level is meant for the most demanding roughness, staying stable through repeated big impacts.

Balanced fit - a versatile position for long rides and faster efforts. This is mainly because bar height comes out ~30 mm below the saddle (very small), with about 634 mm of forward reach - a very long stretch. Expect a lean angle around 26 degrees.

This rating is mainly driven by the parts that affect adjustability: This front-end is not locked into a one-piece system, which helps adjustability, Internal routing is a mild hit to swap-and-go adjustability. At the same time, The dropper adds a real-world adjustability benefit while riding. That is why we tag it Moderately Adjustable. Put simply, it describes how practical it is to reconfigure your position later.

Ride comfort is 8.5/10 — on a real ride it feels very smooth. That’s why it’s labeled Comfortable. 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.

For the spec, this feels competitively priced. 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 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: €7.560 listed versus about €7.658 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 setup suits steeper, rockier terrain and harder hits. It has about 172 mm of suspension travel (how much it absorbs bumps), which helps on rough, technical trails. The Full setup supports this riding style.
