Orbea Denna M20i 2026 - Electric Gravel Bike

Built to conquer unpredictable terrain and ride further with ease, the Orbea Denna M20i takes the heart of a performance gravel bike and adds intuitive, lightweight e-assist power. The Shimano EP801 motor delivers a responsive 85Nm torque, giving you support where you need it, especially useful when the road kicks up or the route stretches out. Paired with Orbea’s compact 420Wh battery, it delivers power in a low-profile, efficient setup ideal for long gravel rides or weekend escapes.

Drive Information:
- Motor: Shimano EP801 mid-drive motor with 85Nm max torque
- Battery: Orbea 420Wh internal battery for balanced weight and range
- User Interface: Shimano remote switch with GRX Di2 integration
The frame is full carbon with a carefully tuned layup for controlled flex and vibration damping, smoothing out rough surfaces while keeping handling crisp. A carbon Denna OMR fork up front and wide 700x45c gravel tyres give excellent traction and stability on everything from loose fire roads to tarmac and compact trails.
Shifting is handled by Shimano’s GRX Di2 electronic system with an XT Di2 rear mech, offering effortless and precise changes across the wide-range 10-51T cassette. Meanwhile, Shimano RX820 hydraulic brakes bring assured, all-weather braking power.
With its performance-focused geometry, carbon wheels and gravel-specific finishing kit—including Easton EC90 AX bars and a carbon post—the Denna M20i is made for riders who want to keep pushing boundaries, not bikes. Whether you're planning an ultra-distance gravel challenge or just want to make your everyday ride more exciting, this is a fast, functional e-bike that’s ready to go.

* Mountain bikes are sized differently to road bikes. Typically, they are sized in inches as the first MTBs were produced in the USA. European brands like Lapierre and Haibike like to use centimeters for all their bikes. The measurements of their mountain bikes doesn’t match their road bikes but is like a simple conversion from the inches measurement. This is why we have included cm measurements in brackets for the e mountain bike column.
