Product Details
The Orbea Denna H50 20MPH is designed for gravel adventurers who believe the best adventures never end and there's always something exciting just around the corner. Built around the philosophy of removing limits, this electric gravel bike combines gravel-tuned assistance with exceptional handling to unlock endless possibilities. Whether tackling the steepest climbs, navigating the loosest surfaces, or embarking on the longest rides, Denna delivers power when you need it and range when it matters most, making big days in the saddle a pleasure.
Powered by the Shimano EP600 motor with Orbea's specially-tuned RS Gen2 RC firmware, Denna delivers up to 85Nm of torque with natural, powerful assistance developed specifically for gravel riding. The RC (Road Control) tune offers two pre-configured profiles: Gravel mode for the most natural ride and longest range on smoother surfaces, and Gravel+ mode with more torque at lower cadences to maximize traction on loose terrain. The advanced 420Wh battery provides up to 3,500m of climbing capability in ECO mode, with optional 210Wh Range Extender available for the most epic rides.
The High Polished Alloy frame features Orbea's gravel-specific geometry with a shorter seat tube for optimized vibration absorption, longer top tube for precise off-road handling, lower bottom bracket for stability, and balanced weight distribution that makes Denna easy to ride when things get difficult. Frame absorption points at key locations allow controlled vertical flex to quiet trail chatter while resisting lateral flex to maintain pedaling efficiency. The OMR carbon monocoque fork offers longer legs for compliance, a stiff crown for precise tracking, and clearance for up to 50C tires—wide enough to fit many mountain bike tires for maximum grip and comfort.
Perfect for riders seeking limitless gravel adventures with powerful electric assistance and added practicality, the Denna H50 includes rear pannier mounting points for longer getaways, fender mounts, and custom frame bag compatibility. Shimano ecosystem integration provides instant, lag-free power that feels natural and alive, with optional EN600 display and Garmin connectivity for complete ride data access.
