Orbea Denna M31e 28mph

The Orbea Denna M31e 28MPH is all about removing limits through joyful adventure. Built for riders who believe the best adventures never end, this gravel e-bike delivers gravel-tuned assistance providing power for the steepest climbs, traction for the loosest surfaces, and range for the longest rides. No matter the terrain, wide tire clearance and a frame designed for smooth riding make big days in the saddle a pleasure.

Built around the Orbea Denna Hydro aluminum frame with High Polished construction, each weld on the main frame is polished smooth, matching the aesthetics of a monocoque frame while tailoring tube shapes and wall thicknesses to offer the same ride feel as carbon frames. The gravel-optimized geometry features shorter seat tube with slightly relaxed angle for optimized vibration absorption, longer top tube working with shorter stem for precise off-road handling, and size-tuned fork trail for stability and precision across all sizes. Lower bottom bracket and longer wheelbase boost stability and comfort on rough surfaces through balanced weight distribution.

The Shimano EP801 motor with RS Gen2 RC firmware delivers gravel-tuned assistance central to Denna's go-anywhere capabilities. RC (Road Control) tune provides natural, powerful assistance developed specifically for narrower tires with full torque capability up to 85Nm and 350W maximum power delivery tuned for control on loose surfaces. Two pre-configured profiles—Gravel for natural ride with longest range on smoother surfaces, and Gravel+ for more torque at lower cadences on looser terrain—optimize performance across varied conditions.

The advanced 420Wh Orbea Internal battery packs latest generation 5.8Ah cells for class-leading energy density, offering approximately 3,500m of climbing in ECO mode (6 hours ride time) through energy savings from RS Gen2 RC firmware. Optional 210Wh Range Extender adds capacity for the most epic rides, weighing just 1.05kg. Shimano ecosystem integration provides instant, lag-free power that feels natural and alive through accurate sensors and fastest monitoring capabilities.

The Denna carbon fork uses robust crown, rounded blade profile, and longer legs with OMR monocoque construction for optimal combination of comfort, 50C tire clearance with 5mm side clearance, and torsional stiffness. Frame absorption points with specifically shaped tubes allow controlled vertical flex while resisting lateral flex, maintaining pedaling efficiency and handling while quieting trail chatter.

SRAM Rival XPLR AXS 13-speed wireless drivetrain delivers precise electronic shifting optimized for gravel demands, while Oquo Road Control RC30TEAM wheels provide dependable performance. Adventure-ready features include rack and fender mounts, dual water bottle capability, and frame bag mounting points. Perfect for riders breaking free from preconceived limits, Denna M31e unlocks endless new adventures through powerful assistance, balanced handling, and innovative solutions.
