Sonni Downhill Complete

On an MTB, the speed score centers on rolling efficiency when you're pedaling, especially on easier terrain. It ends up here thanks to typical trail-width tires, wheel momentum that helps it carry speed between pedal strokes, mid-size wheels that balance agility and momentum, and a capable drivetrain that supports steady speed.

Climbing rating: 2.2/10. Within e-mountain bikes, it lands below average. The lowest gear is very tall when the road tilts up. That lowest gear comes out around 31.4 gear inches. On the ‘easier low gear’ scale, it sits around ~6% versus similar bikes. Gear inches is basically “how easy is the easiest gear”. Lower numbers help you keep your legs spinning on steep bits. E-assist can take the sting out of steep ramps, especially at lower speeds. On proper hills, you’ll feel it — this setup isn’t built to make climbing effortless. 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 rating is 10/10 — “Extreme rough-terrain ready”. This level targets big hits and very rough trails, prioritizing stability under repeated impacts. Full suspension helps the bike stay calmer under braking and cornering on rough sections. It’s tuned for steep, rough terrain where keeping the wheels tracking under hard hits is the priority.

Sporty fit - more tuck for efficiency, but still manageable for many riders. Because handlebar height is roughly 85 mm lower than the saddle (large drop), and how far you'll be stretched forward is about 626 mm (very long). Plan for roughly 35 degrees of lean.

So it lands in Moderately Adjustable. This rating is mainly driven by the parts that affect adjustability: Separate bar and stem components keep fit changes practical; Less routing complexity makes swaps and adjustments more practical.

Comfort comes out to 8.5/10, which usually translates to a plush ride. Within Downhill, Firm basically means 'less plush than the softest builds' even though the ride still feels plush. 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 what you get, the price looks very hard to beat. 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 comes in about 10% under the typical level for similar builds. Against similar bikes of the same type and age, it’s usually on the cheaper side, beating about 92% of listings. Quick reference: €7.138 listed versus about €7.915 for a comparable build. Overall, it looks like a great-value pick in its category.

This setup is built to handle steep lines and heavy impacts. It has about 200 mm of suspension travel (how much it absorbs bumps), which is useful for big hits and steeper descents. Overall, the setup matches this surface range well.
