When the riding is smooth, speed comes down to resistance and weight, and that's what this rating emphasizes. It ends up here thanks to a heavier build, an aero-leaning setup that reduces drag at higher speeds, narrow road tires that keep resistance low, and a more budget-friendly drivetrain that focuses on value. Put together, they influence both acceleration and the effort needed to hold speed.

Uphill performance score: 4.6/10. Within e-road bikes, it lands around the middle. You may find yourself pushing a bit more on steeper grades. That lowest gear comes out around 28.7 gear inches. Compared with similar bikes, this low gear is easier than about ~33% of them. We use “gear inches” as a shortcut for climbing gearing. Lower numbers mean you can spin more easily when it gets steep. Weight is around 15.4 kg, which you notice more on longer or slower climbs. The motor support helps you keep rolling when the slope kicks up. Good for keeping cadence steady on climbs without overcooking it. 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.

Category-wise (gravel), with a 4.9/10 aero score, with ~25mm tyres, it keeps decent wind efficiency without becoming a specialist so you get some benefit when the wind matters. What that means on the road is: it’s a balanced middle ground: some streamlining, but not an extreme aero setup. The gravel tag is a useful clue for how wind efficiency ranks among the priorities. Tyres around 25mm fit a faster road setup and usually keep drag in check. A tidier cockpit and cable routing can help a little once you’re riding quickly. In practice, it’s a balanced setup: decent in the wind without demanding big compromises elsewhere.

Balanced fit - a versatile position for long rides and faster efforts. This is mainly because the bar sits about 102 mm below the saddle (a large drop), and you'll be stretched forward about 548 mm in total (long). You'll likely be near 40 degrees of lean. Gravel geometry often balances comfort and control over rough surfaces. Estimated spacers: ~18 mm.

In E-bikeRoad, So we classify it as Adjustable. Here is the simple reasoning behind the fit flexibility rating: This front-end is not locked into a one-piece system, which helps adjustability. At the same time, Internal routing is a mild hit to swap-and-go adjustability. Put simply, it describes how practical it is to reconfigure your position later.

This scores 2.8/10 for comfort, so it feels quite direct out on the road. So it’s tagged Race-Stiff overall. It’s running about 25 mm tires on 700c wheels, and you feel more of the road texture with narrow tires on rough lanes and gravel patches. The posture is neutral (posture 6/10, torso ~40°), which balances comfort and responsiveness pretty well.

This sits around the normal range for similar bikes. 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). Based on the spec estimate, it’s about 11% above the typical level for similar builds. Among comparable bikes, it sits around the middle on price (cheaper than about 45% of listings). Quick reference: €4.599 listed versus about €4.153 for a comparable build. Bottom line: it’s a normal deal — not amazing, not terrible.

This setup works well when your ride switches between tarmac and easy unpaved sections. The tire size is around 25 mm, which supports mixed routes without feeling slow on road. It’s listed as Gravel, but the setup aligns better with All Road.
