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: wide, grippy tires that trade speed for traction and a solid drivetrain that supports efficient riding. It won't change your fitness, but it can change how fast the bike feels for the same effort.

If your rides include hills, it rates 7.4/10 for climbing. Within e-mountain bikes, it ranks above average. On climbs, the lowest gear feels very easy. In numbers, the low gear is roughly 18.0 gear inches. Compared with similar bikes, this low gear is easier than about ~70% of them. Think of “gear inches” like a difficulty score for your easiest gear: lower = more spin-friendly on climbs. The motor support helps you keep rolling when the slope kicks up. It’s set up so climbs feel controlled rather than a grind. 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.

Suspension sits at 9/10, in “Extreme rough-terrain ready”. That’s built for big impacts and very rough terrain, where keeping wheels tracking matters most. Full suspension helps the bike stay calmer under braking and cornering on rough sections. This level is meant for the most demanding roughness, staying stable through repeated big impacts.

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.

Comfort comes out to 8.6/10, which usually translates to a highly forgiving ride. So it’s tagged Ultra Smooth overall. It’s running about 68 mm tires on 29" wheels, and the big tires calm small hits and take the edge off trail chatter 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 value looks a bit weak compared with similar options. 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 17% above the typical level for similar builds. Among comparable bikes, it sits around the middle on price (cheaper than about 45% of listings). To anchor it: price €8.925 versus an estimated €7.631 for a similar build. Put simply: it’s a bit pricey for what you get.

This setup suits steeper, rockier terrain and harder hits. It has about 170 mm of suspension travel (how much it absorbs bumps), which helps on rough, technical trails. Suspension type (Full) fits this kind of terrain.
