The Orbea Denna H50 28MPH represents joyful adventure without limits-where the best adventures never end and there&';s always something exciting just around the corner or over the next hill. This gravel e-bike delivers power for the steepest climbs, traction for the loosest surfaces, and range for the longest rides, making big days in the saddle a pleasure regardless of terrain. Built around the Orbea Denna Hydro aluminum frame, this advanced alloy construction features fully polished welds matching monocoque frame aesthetics. Tailored tube shapes and wall thicknesses deliver the same smooth ride feel as carbon frames, with strategically shaped absorption points providing controlled vertical flex to absorb bumps and trail chatter while resisting lateral flex for maintained pedaling efficiency and handling precision. The Shimano EP600 motor features Orbea&';s specially tuned RS Gen2 RC firmware, Rider Synergy technology that allows rider and bike to work in perfect harmony for the most natural ride experience. This gravel-tuned assistance delivers up to 85Nm of maximum torque and 350W power, with RC (Road Control) tuning developed specifically for narrower tires. Two pre-configured profiles optimize performance: Gravel mode for natural riding and longest range on smoother surfaces, and Gravel+ mode providing increased torque at lower cadences for maximum traction on loose terrain. The advanced 420Wh Orbea Internal battery utilizes latest-generation 5.8Ah cells for class-leading energy density-packing more power into lighter, smaller packaging. The average rider achieves up to 3,500m of climbing in ECO mode, with an optional 210Wh Range Extender (weighing just 1.05kg) available for epic adventures. Energy-efficient RS Gen2 RC firmware maximizes range without compromising performance. Orbea&';s gravel-optimized geometry features shorter seat tube with relaxed angle for enhanced vibration absorption, longer top tube working with shorter stem for precise off-road handling, and size-tuned fork trail ensuring stability and precision across all sizes. Lower bottom bracket positioning and longer wheelbase enhance stability and comfort, while balanced weight distribution creates easy handling when conditions get difficult. Generous 50C tire clearance accommodates mountain bike tires for maximum grip and comfort. Shimano Cues drivetrain provides reliable shifting optimized for e-bike demands, while alloy 700c wheels deliver dependable performance across varied surfaces. The Shimano ecosystem integration offers instant, lag-free power through accurate sensors and fast monitoring, with assist mode control via left brake lever and optional Garmin connectivity for battery and motor information. Perfect for adventurous cyclists seeking to break free from preconceived limits, the Denna H50 unlocks endless new adventures through powerful assistance, exceptional handling, and rack/fender mounting capability ready for longer getaways.
