Orbea unveils Denna: A fancy shmancy mid-drive electric road bike tuned for gravel

The latest addition to Orbea’s electric road bike lineup is here, and it’s designed to handle more than just pavement. The Orbea Denna, announced today, is a gravel-optimized electric road bike that builds on the company’s previous experience with models like the Gain and Terra. Featuring a mid-drive motor “tuned specifically for off-road conditions”, the Denna aims to blend power, range, and versatility for riders looking to tackle everything from steep climbs to loose trails.

At the heart of the Denna is Orbea’s RS Gen2 RC system, a customized version of Shimano’s EP platform. The RS (Rider Synergy) branding refers to Orbea’s firmware tweaks that aim to deliver a more natural ride feel by adjusting power delivery to match rider input.

The second-generation update increases the motor’s torque output to 85 Nm, giving it plenty of climbing ability, especially on rougher terrain.

The Denna offers two built-in power modes:

• Gravel mode is tuned for smoother gravel roads, offering a more efficient power delivery at higher cadences.

• Gravel+ mode adjusts torque for looser terrain, delivering extra power at lower cadences to improve traction.

Riders can further tweak the assist settings through the Shimano e-Tube app, dialing in torque output to match their riding style.

Orbea designed the Denna with tire clearance up to 50c, allowing riders to customize their setup based on terrain. The frame geometry includes:

• A lower bottom bracket for stability

• Optimized chainstay length for balance between responsiveness and comfort

• A longer wheelbase to improve handling over uneven terrain

• A size-specific fork trail for consistent ride quality across all frame sizes

The OMR carbon frame and fork are built for both stiffness and compliance, allowing an interesting mix of vertical flex to absorb road vibrations while maintaining lateral rigidity for efficient pedaling.

The Denna is powered by a 420Wh battery, which Orbea claims can support up to 3.5 km (2.5 miles) of elevation gain in Eco mode. That’s not exactly the most common way to measure battery capacity, but most electric road bikes with similar sized batteries tout flat land ranges of 120-150 km (75-90 miles) per charge.

For riders who need even more range, an optional 210Wh range extender battery that is roughly the size of a water bottle adds extra distance without significantly increasing weight.

While range extenders are less common for everyday e-bikes, electric road bikes and gravel bikes are uniquely relevant candidates, as riders of these types of bikes often head out on extended rides covering significant distances.

Riders can switch between assistance modes using the left brake lever, and the system is compatible with multiple display options, including Shimano’s EN600 unit or a paired Garmin device for real-time battery and motor data.

For added utility, all Denna models include mounting points for fenders and two water bottle cages, making it adaptable for long-distance adventures.

Orbea is offering the Denna through its MyO customization program, allowing buyers to select components, colors, and finishes to match their riding style—whether that means a more road-oriented build or a full gravel setup.

Joseba Arizaga, Orbea’s Road Product Manager, summed up the company’s vision for the Denna:

‘’We are thrilled to be launching Denna today. It represents the next evolution of eRoad riding—where power, range, and capability come together to break down barriers and redefine what’s possible. With our Rider Synergy concept and gravel-specific tuning, Denna provides a seamless, natural ride feel that enhances every adventure, whether on smooth tarmac, rugged backroads or both. It’s not just about assistance; it’s about expanding the ride, unlocking new routes, and pushing further than ever before.”

Last but not least (definitely not least), prices can be found below. They range considerably for the different models that feature higher spec loadouts of key components.
