Spark ST 900 Tuned TR

In mountain-bike land, this is a pedaling-speed measure - how fast it rolls when you're working for it. What pushes it in this direction is a light setup, wheel momentum that helps it carry speed between pedal strokes, typical trail-width tires, and a high-end drivetrain that tends to feel crisp under load. Add it all up and you get a clear tilt toward speed or toward utility.

Overall on climbs: 9.6/10. Within Mountain bikes, it sits near the top. On climbs, the lowest gear feels very easy. In numbers, the low gear is roughly 17.8 gear inches. In its peer group, it lands around the easier ~52% for low-gear climbing. Gear inches is basically “how easy is the easiest gear”. Lower numbers help you keep your legs spinning on steep bits. At roughly 11.9 kg, the bike’s heft shows up most on sustained climbs. It’s set up so climbs feel controlled rather than a grind. 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 effectiveness is 7/10. That aligns with “High-impact ready”. It typically supports higher-speed rough sections where impacts stack up quickly. Full suspension helps the bike stay calmer under braking and cornering on rough sections. This level is meant to keep the bike composed when hits are bigger and frequent. On rough trails, this level aims to keep the bike settled under braking and cornering through repeated hits.

Sporty fit - more tuck for efficiency, but still manageable for many riders. You get this posture because bars are around 57 mm lower than the saddle, which is a moderate drop, and the forward stretch measures around 617 mm (very long). Estimated lean is about 30 degrees.

Net result: Adjustable. Why this fit flexibility rating: This front-end is not locked into a one-piece system, which helps adjustability, Routing is relatively straightforward, which helps when you change cockpit parts; Having a dropper increases how adaptable the bike feels in different situations. Put simply, it describes how practical it is to reconfigure your position later.

Ride comfort is 7.8/10 — on a real ride it feels highly forgiving. Within Trail, Balanced basically means 'less plush than the softest builds' even though the ride still feels highly forgiving. The posture is forward, attacking (posture 7/10, torso ~30°), which puts you in an attack stance, which can feel more intense on long, rough descents.

The price looks hard to justify versus 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). On the spec comparison, it sits roughly 101% above what similar builds typically cost. In its peer group, it’s one of the pricier listings, beating only about 6% of them. Quick reference: €10.985 listed versus about €5.476 for a comparable build. Overall, you can likely find better value elsewhere.

This bike is built for everyday trails with a mix of roots, rocks, and turns. It has about 120 mm of suspension travel (how much it absorbs bumps), which works well for everyday trails. The Full setup supports this riding style.
