SONIC SX 2

For off-road use, the score focuses on how quickly the bike accelerates and keeps speed on hardpack and gravel paths. The strongest influences are typical trail-width tires, wheel momentum that helps it carry speed between pedal strokes, and a solid drivetrain that supports efficient riding. In combination, they decide how the bike feels when rolling along.

On steep roads, it comes in at 7.0/10. Within e-mountain bikes, it ranks above average. It’s set up for steady spinning on climbs. In numbers, the low gear is roughly 18.2 gear inches. Compared with similar bikes, this low gear is easier than about ~59% of them. Think of “gear inches” like a difficulty score for your easiest gear: lower = more spin-friendly on climbs. E-assist can take the sting out of steep ramps, especially at lower speeds. 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.

Suspension rating is 6/10 — “Confident trail control”. This usually points to stronger bump control and steadier tracking when the surface gets choppy. It’s a common compromise: calmer front wheel, efficient rear end. Expect more grip and stability compared with basic bump-control setups. On roots and rocks, it should keep the bike calmer through repeated impacts. It should keep the bike more controlled on mixed surfaces, especially through repeated small-to-medium impacts.

Balanced fit - a middle ground between comfort and speed. This is an estimate; exact fit varies by spacers and rider setup.

This rating is mainly driven by the parts that affect adjustability: Standard cockpit parts make it simpler to fine-tune your position over time, A more service-friendly routing setup makes changes easier. Plus, From the seatpost text provided, there are no strong constraints or bonuses. So we classify it as Adjustable. Put simply, it describes how practical it is to reconfigure your position later.

Comfort comes out to 6.6/10, which usually translates to a nicely smooth ride. So it’s tagged Firm overall. The posture is neutral (posture 5/10), which gives a steady, predictable feel without pushing you too far forward.

This looks like a high asking price for the build level. 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 comparison, it sits roughly 40% above what similar builds typically cost. In its peer group, it’s one of the pricier listings, beating only about 24% of them. To anchor it: price €6.720 versus an estimated €4.790 for a similar build. Bottom line: the price looks high for what’s included.

This setup is aimed at fast trail riding on less extreme terrain. It has about 120 mm of suspension travel (how much it absorbs bumps), which suits smoother trails. Suspension type (Hardtail) fits this kind of terrain.
