Orbea Denna M40 Electric Gravel Bike - 2026

Orbea Denna is all about removing limits. Gravel-tuned assistance offers power for the steepest climbs, traction for the loosest surfaces and range for the longest rides. No matter the terrain, wide tire clearance and a frame designed for a smooth ride make big days in the saddle a pleasure.

The Horizon Beckons

Break free from preconceived limits. Denna's powerful, gravel-tuned assistance delivers control when you need it, while its balanced weight distribution and smart geometry ensure exceptional handling, unlocking endless new adventures.

Go Anywhere with More Control

Our specially tuned EP8-RS motor is central to Denna's go-anywhere capabilities. Weight, power and simplicity plus a best-in-class battery range means you can rewrite your idea of what is possible.

RC Tune: Full Torque and Balanced Power

Using the Shimano e-Tube app riders can configure up to 85 Nm of Torque, for the steepest and loosest paths. The maximum power is 350 W and the power delivery is tuned for control on looser surfaces.

Orbea Gravel Geometry

No matter what your definition of gravel, great geometry helps to make riding rougher surfaces easy.

• Shorter seat tube - Using a shorter seat tube with a slightly more relaxed angle optimises vibration absorption and vertical compliance.
• Optimised chainstay length - Long enough to smooth out the ride but short enough for quick handling.
• Longer top tube - Works with a shorter stem for precise handling off road.
• Size-tuned fork trail - Stability and precision for all sizes.
• Lower BB - Lowers the center of gravity to provide a more stable ride on rough surfaces.
• Longer wheelbase - Boosts stability and comfort

Balanced weight distribution

Easy going handling comes form a low center of gravity and gravel-tuned geometry which make Denna easy to ride when things get difficult.

50C Tire Clearance

Gravel can take you almost anywhere, so needs can vary. If you rarely venture away from back-roads, you may want narrower tires. Others seek out the wildest places and appreciate a bigger tire. Denna has clearance for up to 50C tires, so you can fit many mountain bike tires for maximum grip and comfort.

Smooth Ride

At home on every terrain, Denna’s finely tuned frame delivers controlled flex, adapting to rough surfaces without sacrificing composure or draining your energy.

420 Wh Battery

Our 420 Wh battery offers more power in a lighter, smaller package. Thanks to the energy savings from our RS Gen2 RC firmware, the average rider will get up to 3,500 m of climbing from this battery.

Class-leading energy density

Packing more energy into a smaller space, with less weight, is key for lightweight e-bikes. Our custom batteries offer the highest energy density on the market, meaning you can go further, without adding extra weight.
