HULK 4.0 Carbon Gravel Bike 20S

This road-speed measure focuses on efficient pace on asphalt, where drag and rolling resistance matter most. A few practical factors stand out: 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. Over longer efforts, it's tuned for reliability and control rather than maximum speed.

Climb score: 5.0/10. Within Road bikes, it lands around the middle. The easiest gear is on the tall side for proper hills. In numbers, the low gear is roughly 31.2 gear inches. On the ‘easier low gear’ scale, it sits around ~30% versus similar bikes. Think of “gear inches” like a difficulty score for your easiest gear: lower = more spin-friendly on climbs. Weight is around 10.2 kg, which is typical for this kind of build. It won’t be the absolute best climber, but it won’t hold you back on most climbs either. Specs can vary by size and build, and some manufacturer details aren’t always published, so treat this as a strong guide rather than a guarantee.

In gravel terms, aero-wise, at 4.4/10, it leans toward real-world stability first with less emphasis on airflow tricks. The short version is: it’s more about stability and everyday comfort than cutting through the wind. Tyres around 40mm are clearly aimed at comfort and control, and that usually adds some drag in the wind. That typically translates to easy, confidence-inspiring riding rather than chasing speed in the wind.

Comfort fit - less tuck and easier on neck and shoulders. Gravel setups typically avoid an extreme tuck for stability. This is an estimate; exact fit varies by spacers and rider setup.

Why this fit flexibility rating: Because the bar and stem are separate, changing reach or bar shape is usually straightforward. Also, The front-end is easier to work on, supporting fit tweaks over time. So we classify it as Adjustable. In practice, it is about how easy fit changes are with normal parts and service work.

Ride comfort is 6.0/10 — on a real ride it feels balanced. 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.

For what you get, the price looks very hard to beat. 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 43% 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 96% of listings. To anchor it: price €1.599 versus an estimated €2.792 for a similar build. Overall, it looks like a great-value pick in its category.

This setup is built for mixed rides where gravel is a normal part of the route. Tires around 40 mm are well suited for gravel roads and unpaved connectors. Overall, the setup matches this surface range well.
