ORBEA: Denna M20i - 28mph - Carbon Electric Gravel Bike

Custom order made in Spain.

Introducing the Orbea Denna Electric Gravel Bike at Bike Attack Electric that can go up to 28mph with Shimano XT Di2 Electronic Shifting: Unleash the Future of Precision Gravel Cycling.

The Orbea Denna at Bike Attack Electric is an advanced electric gravel bike crafted for riders who crave freedom beyond the pavement. Powered by the refined Shimano EP8-RS drive unit, it delivers smooth, responsive support that feels completely natural—whether you're powering up steep inclines or cruising rolling dirt paths. The lightweight OMR carbon frame is tuned for all-day comfort without compromising stiffness or control, while its geometry is dialed in for confident handling over unpredictable terrain.

Equipped with a high-efficiency 420Wh battery, the Denna provides generous range for demanding rides, with the option to expand your capacity using a 210Wh range extender. Its clearance for wide 50c tires ensures grip and adaptability over gravel, mud, or loose backcountry roads. Integrated features like internal cable routing, mounts for racks and fenders, and ergonomic cockpit configurations add to its versatility, making it equally suited for multi-day bikepacking trips or long-distance mixed-surface explorations.

With performance-focused engineering and elegant design, the Orbea Denna isn’t just built to handle the journey—it’s built to inspire it.
