Orbea Denna H50: Freedom Without Limits

The Orbea Denna H50 is designed for riders who refuse to let the terrain dictate their journey. Whether you're tackling the steepest Lakeland climbs or cruising across loose fire roads, this electric gravel bike provides the perfect balance of natural-feeling assistance and rugged performance. Built around a high-polish hydroformed alloy frame and a vibration-absorbing carbon fork, the Denna H50 is your ultimate companion for "big days" in the saddle.

Power & Synergy: The Shimano RS Ecosystem

At the heart of the Denna is the Shimano EP6-RS Gen2 motor, specifically tuned by Orbea for gravel riding. This "Rider Synergy" (RS) firmware ensures the motor works in harmony with your pedalling, providing up to 85Nm of torque only when you need it.

• Gravel Mode: Optimised for smooth surfaces and maximum range.

• Gravel+ Mode: Provides extra bite and control on loose, technical climbs.

• Customisable Power: Use the Shimano E-Tube app to fine-tune your assistance levels on the fly.

Go Further with Smart Battery Tech

Equipped with a best-in-class 420Wh internal battery, the Denna H50 is built for endurance. Thanks to the efficiency of the RS motor tuning, you can expect enough range for up to 3,500m of climbing in Eco mode. For those epic weekend adventures, the frame is also compatible with an optional 210Wh Range Extender (available separately).

Gravel-Specific Geometry & Comfort

Orbea’s dedicated Gravel Geometry focuses on stability and composure. A lower bottom bracket and longer wheelbase provide a grounded feel on rough descents, while the shorter seat tube allows for better vertical compliance to soak up road chatter.

• 50c Tyre Clearance: Run wide, high-volume tyres for maximum grip and comfort on the wilder trails.

• Full Carbon Fork: Reduces front-end weight and filters out high-frequency vibrations.

Reliable Components for Every Condition

The Denna H50 doesn't just look the part—it’s built with durable, high-performance kit to handle the UK’s unpredictable conditions.

• Shimano CUES 10-Speed Drivetrain: Smooth, reliable shifting with a wide 11-48t range for any incline.

• Shimano RS405 Hydraulic Disc Brakes: Confident, all-weather stopping power.

• Vittoria Terreno Dry Tyres: Fast-rolling on the tarmac, with aggressive side knobs for cornering on the dirt.
