Powerfly FS 4 Gen 2

It's quick enough for most rides, but not a pure fastest-possible build. On smoother singletrack, faster-rolling tires and lighter builds show up clearly, and that's what this score reflects. The main reasons are a heavier build, wheel momentum that helps it carry speed between pedal strokes, typical trail-width tires, and mid-size wheels that balance agility and momentum.

If your rides include hills, it rates 4.7/10 for climbing. Within e-mountain bikes, this comes out around the middle. On longer climbs, the gearing lands on the tall side. In numbers, the low gear is roughly 21.5 gear inches. In its peer group, it lands around the easier ~16% 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 about 24.8 kg, it’s a heavy build; the low gear matters even more when the slope kicks up. Being an e-bike helps on climbs because the assist adds steady push when you need it. 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 handling is rated 6/10. It matches “Confident trail control”. This usually points to stronger bump control and steadier tracking when the surface gets choppy. With suspension in the front and rear, the bike can stay more settled through repeated bumps. It should keep the bike more controlled on mixed surfaces, especially through repeated small-to-medium impacts.

Comfort fit - less tuck and easier on neck and shoulders. It feels this way because handlebar height is roughly 3 mm lower than the saddle (very small drop), and how far you'll be stretched forward is about 567 mm (long). You'll likely be near 22 degrees of lean.

This rating is mainly driven by the parts that affect adjustability: A modular front-end gives more freedom to change stem length or bar width - Internal cable routing can slow down fit-related part changes. That is why it is in the Adjustable bucket.

Ride comfort is 7.4/10 — on a real ride it feels nicely smooth. So it’s tagged Comfortable overall. The posture is neutral (posture 5/10), which gives a steady, predictable feel without pushing you too far forward.

For the spec, this feels competitively priced. 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). On the spec estimate, the price is close to what we’d expect for a comparable build. Among comparable bikes, it sits around the middle on price (cheaper than about 52% of listings). Quick reference: €3.999 listed versus about €4.238 for a comparable build. Overall, it looks like a strong buy in its category.

This bike is best for smoother trails where speed and efficiency matter. It has about 100 mm of suspension travel (how much it absorbs bumps), which suits smoother trails. Overall, the setup matches this surface range well.
