ORBEA Denna H30

The Orbea Denna H30 Gravel isn’t just an e‑bike, it’s a narrative of adventure without boundaries. Crafted for riders who seek freedom from terrain constraints, it merges natural-feeling electric assistance with gravel-specific performance, enabling longer rides, steeper climbs, and rougher surfaces. All without compromising ride comfort or stability.

The range of Denna eGravel bikes offer weights as light as 13kg, give or take for the carbon models and 16kg for the alloy frame version.

Frame & Comfort

Orbea’s light weight aluminium frame maintains lateral stiffness for efficient power transfer and nimble handling. Furthermore, a low bottom bracket, refined chainstays, and a balanced trail tailored to each size deliver stable yet responsive steering, especially on mixed and loose surfaces.

Cleared for up to 50mm tyres, the ORBEA Denna H30 provides extraordinary flexibility to maximise grip and comfort over varied terrain. Experience comfort in all terrains with this unique eBike.

Power and Long Range

Equipped with the Shimano EP600 mid-drive motor, the Orbea Denna H30 Gravel ebike pairs with RS Gen2 RC tuning for gravel conditions. It delivers up to 85 Nm of torque, offering responsive and highly effective assistance. Riders can choose between ‘Gravel’ mode for smoother surfaces and ‘Gravel+’ for looser terrain traction. In addition, further customisation is available via the Shimano e-Tube app.

A compact internal 420Wh battery achieves up to approximately 3,500m of climbing in Eco mode. This offers an impressive energy-to-weight ratio. Also, riders can extend range further with an optional 210Wh Range Extender. It is cleverly disguised as a water bottle that mounts on the frame.

Built-in sensors, compatibility with Garmin devices, and optional Shimano EN600 display let you monitor and customise performance on the fly. These features enhance your time with the ORBEA Denna H30.

Drivetrain & Controls of the Orbea Denna H30 Gravel

A Shimano GRX RX822 GS 12-speed derailleur provides smooth and relatively silent shifting. It couples with a wide range 10–45T cassette that handles steep climbs and flat sprints efficiently. As a result, this ensures crisp, durable shifting. Braking is gradual and highly effective thanks to Shimano RX410 hydraulic disc brakes. These offer confident, well-modulated stopping power across all conditions.

How do I measure my height?

With your shoes off, stand upright against a wall, with your shoulders back and legs together. Use a pencil to make a small mark on the wall above your head (make sure you hold the pencil parallel to the floor). Then measure from the floor to your mark, in centimetres or feet and inches.

How do I measure my inside leg length?

With your shoes off, stand upright with your back against a wall. Place a book/ruler between your legs, level with your crotch. Then measure from the floor to the top of the book/ruler, in centimetres or feet and inches (it’s easier if a friend helps).

Q & A

Do all brands of ebike use the same unit of measurement?

No. Most brands show sizing in centimetres, however some use a S/M/L system, and others use inches. The table above includes all of these variations to help you find the right size.

Which size should I go for if I'm in between those listed?

If your measurements suggest that you have a choice of two different sizes, then in the end it’s a personal choice. Here are some rules of thumb to consider: Touring/Trekking ebikes - choose the smaller size. It is possible to make a smaller frame bigger (for example, by raising the saddle or fitting a longer the stem), whereas if the frame itself is too big for you, it’s likely to be less comfortable and won't feel right. eMTBs - choose the larger size. You’ll find an eMTB with a slightly larger frame easier to handle than one that feels cramped. You can always fit a shorter stem if necessary to reduce the reach to the handlebars.

How are ebike frame sizes measured?

An electric bike’s frame size is calculated by measuring the distance from the top of the seat tube (where the seat post inserts), to the centre of the front chainring. Sizing Guide
