The Orbea Denna M40 2025 is Orbea's next-generation electric gravel bike, designed for riders who want to venture beyond the pavement with confidence. Combining a lightweight carbon frame, gravel-specific geometry, and an intelligent Shimano drive system, the Denna M40 is equally at home on remote gravel roads, forest trails, bikepacking adventures, and fast all-road rides.
Whether you're climbing steep fire roads, covering long mixed-terrain routes, or discovering new backcountry adventures, the Denna M40 delivers natural assistance while preserving the responsive feel of a premium gravel bike.
Power comes from Orbea's exclusive Shimano EP801 RS RC drive unit, specially tuned for gravel riding.
✔ 85Nm of torque
