HULK 4.0 Carbon Gravel Bike 20 Speed

When the riding is smooth, speed comes down to resistance and weight, and that's what this rating emphasizes. In contrast to speed-optimized builds, this build is shaped by a heavier build, a mass profile that isn't optimized for punchy acceleration, wider mixed-surface tires that add some drag, and a more budget-friendly drivetrain that focuses on value.

If your rides include hills, it rates 5.0/10 for climbing. Within Road bikes, this comes out around the middle. On longer climbs, the gearing lands on the tall side. That lowest gear comes out around 31.2 gear inches. On the ‘easier low gear’ scale, it sits around ~30% versus similar bikes. “Gear inches” sounds nerdy, but it’s just a quick way to describe how easy your lowest gear is to turn uphill. Lower usually means easier. With roughly 10.2 kg to move uphill, you’ll feel it more as climbs get longer. It can climb, but you’ll likely prefer smoother pacing on longer hills. Real-world feel depends on setup and size, and some details aren’t always listed, so this is best seen as a well-informed estimate.

That 4.4/10 aero rating suggests that it’s built for everyday ease over airflow tricks so it’ll feel calm and steady rather than ‘free speed’ fast. What that means on the road is: it’s more about stability and everyday comfort than cutting through the wind. The wheels are on the shallower side (around 30mm), so frame shapes and position likely matter more than wheel depth here. These wheels lean more toward stability and versatility than pure aero. That tyre width leans toward grip and stability first, with a small aero penalty at speed. Not every brand publishes the same detail, so this leans on the clearest available specs. It’s built for ease and control, not for squeezing out speed against the wind.

Comfort fit - a relaxed road posture that stays friendly on longer rides. Based on full geometry data.

In Road / Gravel, Overall, it falls into Adjustable. The cockpit is modular (separate stem and handlebar), so it is easier to adjust or swap fit parts, Cable routing is on the simpler side, which helps adjustability; The listed seatpost details do not show clear restrictions or extra flexibility signals. Put simply, it describes how practical it is to reconfigure your position later.

Comfort comes out to 6.0/10, which usually translates to a moderately comfortable ride. That’s why it’s labeled Balanced. It’s running about 40 mm tires on 700c wheels, and wider tires let you drop pressure a touch, which smooths out rough pavement on rough lanes and gravel patches. The posture is neutral (posture 5/10), which balances comfort and responsiveness pretty well.

Compared to similar bikes, this is priced very competitively. 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 parts list, it’s roughly 39% cheaper than what similar builds typically cost. Against similar bikes of the same type and age, it’s usually on the cheaper side, beating about 95% of listings. Quick reference: €1.699 listed versus about €2.792 for a comparable build. Put simply: this is strong value for what’s included.

This bike is ready for gravel roads while staying efficient on paved stretches. Tires around 40 mm are well suited for gravel roads and unpaved connectors. The wheel setup (700c) supports that direction.
