Orbea Denna H40 28mph

The Orbea Denna H40 28mph is an assisted gravel bike for riders who want more freedom in choosing where a ride leads. Denna combines the pace and versatility of a drop-bar platform with support for longer climbs and changing surfaces. Its character is centered on exploration: the ability to link quiet roads, loose tracks and unfamiliar detours while retaining the involvement that makes a good gravel ride satisfying.

The platform's geometry is a major part of that confidence. A longer top tube works with a shorter stem to give the rider useful control away from smooth pavement, while balanced weight distribution and a low center of gravity help the bike remain composed. The wheelbase favors stability without making the ride feel disconnected. Size-tuned fork trail supports consistent steering across the range, and the frame's shorter seat tube contributes to the design's approach to comfort.

A full-carbon fork combines a substantial crown with longer, shaped legs, balancing accurate tracking with the ability to take the edge off rough ground. Denna's frame design also uses controlled flex to reduce the fatigue of repeated surface chatter while preserving lateral support for pedaling and cornering. Generous clearance gives riders room to choose tires for their preferred mix of tarmac and gravel; the fitted 45 mm tires are distinct from the platform's wider compatibility.

Electric assistance broadens the route options without changing the bike's fundamental purpose. The integrated 420 Wh battery and Shimano drive system support climbing and extended outings, while the gravel-focused layout keeps rider control at the center of the experience. Actual range depends on conditions, rider input and assistance use, rather than a single promised distance. Practical mounting points and the supplied frame bag provide space for ride essentials without requiring an overloaded cockpit. The result is a versatile platform for riders who would rather consider another valley or another unpaved connection than turn back simply because the route has become more demanding.
