THEOS F90 SH 29″/27.5″ 725Wh

This off-road speed score leans toward efficient rolling, not downhill stability or comfort. When you push the pace, it trades speed for comfort, durability, or practicality. A few practical factors stand out: typical trail-width tires, wheel momentum that helps it carry speed between pedal strokes, and a solid drivetrain that supports efficient riding.

Climbing rating: 7.4/10. Within e-mountain bikes, it ranks above average. When it gets steep, the gearing feels very easy. Your easiest gear lands around 18.0 gear inches. On the ‘easier low gear’ scale, it sits around ~70% versus similar bikes. Gear inches is basically “how easy is the easiest gear”. Lower numbers help you keep your legs spinning on steep bits. Being an e-bike helps on climbs because the assist adds steady push when you need it. Good for keeping cadence steady on climbs without overcooking it. 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.

Suspension performance: 9/10. It’s grouped into “Extreme rough-terrain ready”. This level targets big hits and very rough trails, prioritizing stability under repeated impacts. Full suspension means both ends can absorb impacts, helping the wheels track rough ground more consistently. It’s tuned for steep, rough terrain where keeping the wheels tracking under hard hits is the priority.

Comfort fit - a relaxed road posture that stays friendly on longer rides. Based on full geometry data.

Why this fit flexibility rating: Standard cockpit parts make it simpler to fine-tune your position over time, Routing is relatively straightforward, which helps when you change cockpit parts. Also, A standard round seatpost size gives you many options for fit and replacements. That is why it is in the Adjustable bucket.

Ride comfort is 8.5/10 — on a real ride it feels highly forgiving. So it’s tagged Comfortable overall. It’s running about 65 mm tires on 700c wheels, and the high-volume tires add a lot of damping and grip on roots, rocks, braking bumps, and repeated hits. The posture is neutral (posture 5/10), which gives a steady, predictable feel without pushing you too far forward.

The price feels a touch strong for the parts listed. 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 17% above the typical level for similar builds. Compared with similar bikes, it trends a little expensive (cheaper than about 43% of listings). To anchor it: price €8.925 versus an estimated €7.631 for a similar build. Bottom line: you may be paying extra versus similar options.

This bike is built for rougher, more technical trails where control matters. It has about 170 mm of suspension travel (how much it absorbs bumps), which helps on rough, technical trails. Overall, the setup matches this surface range well.
