The Orbea DENNA M20i Gravel E-Bike is designed to remove all limits, transforming every ride into a joyful adventure. Whether you're seeking power for the steepest climbs, enhanced traction on loose surfaces, or extended range for your longest expeditions, Denna delivers. Its generous 50c tire clearance and a frame meticulously engineered for a smooth ride ensure that even the biggest days in the saddle are a pleasure, no matter the terrain.
At the heart of Denna's go-anywhere capabilities is the specially tuned Shimano EP8-RS Gen2 RC motor. RS stands for Rider Synergy, Orbea's proprietary firmware for Shimano EP motors, providing the most natural and seamless ride experience. Gen2 signifies an increased maximum torque of 85 Nm, while RC (Road Control) denotes Denna's specific motor tune, developed to offer powerful yet natural assistance optimized for narrower gravel tires. Riders can choose between two pre-configured profiles: "Gravel" for the most natural ride and longest range on smoother surfaces, and "Gravel +" for increased torque at lower cadences, ideal for looser terrain where maximum traction is needed. Utilizing the Shimano e-Tube app, riders can further configure up to 85 Nm of torque with a maximum power of 350W, with power delivery specifically tuned for control on unpredictable surfaces.
Denna's Orbea Gravel Geometry is crafted to make riding rougher surfaces easy and enjoyable. Key features include a shorter seat tube with a relaxed angle for optimized vibration absorption, an optimized chainstay length for a balance of smooth ride and quick handling, and a longer top tube paired with a shorter stem for precise off-road control. A size-tuned fork trail ensures stability and precision across all sizes, while a lower bottom bracket lowers the center of gravity for a more stable ride. The longer wheelbase further boosts stability and comfort, resulting in a balanced weight distribution that makes Denna easy to manage even when conditions get challenging.
Built for a supremely smooth ride on every terrain, Denna's finely tuned frame delivers controlled flex, adapting to rough surfaces without sacrificing composure or draining your energy. It utilizes Orbea's toughest OMR carbon, featuring high modulus and high strength fibers for improved stiffness-to-weight ratios. Advanced molding technologies prevent wrinkling in critical zones, using less carbon while maintaining superior strength. The Denna Fork, constructed from OMR carbon, features longer legs for absorption, a stiff crown for rigidity and precise tracking, and ample clearance to comfortably fit up to 50C tires with 5mm clearance on each side, along with full ICR internal brake hose routing. Strategically shaped frame absorption points further quiet trail chatter by allowing controlled vertical flex to absorb bumps, all while resisting lateral flex to maintain pedaling efficiency.
Powering your extended adventures is the latest battery technology. Denna is equipped with an Orbea Internal 420Wh battery, offering more power in a lighter, smaller package. Thanks to the energy savings from the RS Gen2 RC firmware, the average rider can achieve up to 3,500m of climbing range from this battery. These class-leading batteries utilize the latest generation 5.8 Ah cells, offering the highest energy density on the market, ensuring you can go further without added weight. For the most epic rides, a 210Wh Range Extender (sold separately) is available, offering additional range in a compact, water bottle-sized package.
Denna is packed with innovative solutions for a seamless riding experience. The Shimano Ecosystem and Orbea's RS Gen2 firmware work in perfect synergy, taking advantage of Shimano's accurate sensors for instant, lag-free, and natural power delivery. Riders can opt for the Shimano EN600 display for on-the-go profile control or comfortably swap between assist modes via the left brake lever, pre-configured from the factory (Di2). Garmin connectivity allows full access to battery and motor information on your existing Garmin watch or GPS device. Additionally, Denna is adventure-ready with mounting points for fenders and two water bottles, while the Denna H model adds rear pannier mounting points for longer getaways.
