Collection: Orbea Gravel & Road E-Bikes — Denna & Gain at EBB

Part of our full Orbea electric bike range — see the main collection for the complete brand overview, eMTB, adventure touring, and commuter categories.

Finding a performance road or gravel ebike that genuinely rides like a serious bike — not a motorised approximation of one — is harder than it sounds. The Orbea Denna does though. At Electric Bikes Brisbane, we’ve been selling Orbea’s gravel and road e-bikes since 2017, and the Denna is one of the most talked-about bikes in our store. Tom, one of our sales specialists who has represented Australia in road cycling at the World Championships, calls it the fastest bike in the building — and he means it. As a Platinum Orbea dealer, we can custom order the full Denna and Gain range, including models not listed on our website, and our workshop is fully accredited for the Shimano motor systems that power them.

Two Bikes. One Philosophy. Different Roads.

Orbea entered the performance electric road and gravel category in 2017 with the Gain, and the Denna followed as a purpose-built gravel platform. Both share Orbea’s OMR carbon frame construction, their own Oquo wheel brand, and a design philosophy that refuses to let a motor compromise the ride. What separates them is their intent:

•  • Orbea Denna — Electric Gravel Bike: Built for the full spectrum of gravel riding — mixed terrain, dirt roads, proper climbing, mudguard mounts, bikepacking compatibility, 50mm tyre clearance. Powered by the Shimano EP8 RS Gen2 RC motor, with Orbea’s own RS (Rider Synergy) firmware tuned specifically to feel like an extension of your own effort, not a push from behind. Gravel mode delivers up to 42Nm; Gravel+ up to 56Nm. The 420Wh integrated battery is claimed to cover 3,000–3,500m of climbing on Eco — real-world testing has returned around 145km on a flat-to-rolling Eco ride.
•  • Orbea Gain — Electric Road Bike: A pure road bike that happens to have a motor. The Mahle X20 rear hub motor is so quietly and smoothly integrated that non-cyclists have ridden the Gain without knowing it was electric. Pure road geometry, up to 35mm tyre clearance, 350Wh Mahle iX350 battery, claimed up to 4,000m climbing. From around 11.5kg on the lightest carbon models — significantly lighter than most mid-drive electric bikes.

The Orbea Denna — In More Detail

The Denna is the centrepiece of this collection. It is available from entry-level alloy (H50, Shimano EP600 RS, $7,799) through to full-carbon flagship models with SRAM Red XPLR AXS 13-speed or Shimano Dura-Ace / XTR Di2 electronic drivetrains (M10i, M11E, $17,499). The carbon models all use Orbea’s OMR carbon frame and fork, with engineered Frame Flex zones that absorb road and trail vibration without added suspension weight — a design philosophy that makes the Denna genuinely comfortable on long rides as well as fast on technical ones.

The Shimano EP8 RS Gen2 RC motor at the heart of the mid-range and flagship models is one of the most sophisticated gravel motor systems available. Orbea worked with Shimano on a custom “RS” (Rider Synergy) firmware and “RC” (Road Control) tuning that makes the motor feel natural — it reads your effort and responds proportionally rather than delivering a fixed push. It runs three assist levels (Eco, Trail, Boost), with 36% less pedalling resistance than the previous generation when the motor is off. The optional 210Wh range extender (under 1kg, fits a standard bottle cage) can effectively double your ride in mixed terrain.

Across the range, drivetrain options include SRAM Red XPLR AXS 13-speed (M11E), Shimano Dura-Ace / XTR Di2 (M10i), Shimano XT Di2 (M20i), SRAM Rival XPLR eTAP AXS (M31E), Shimano GRX 820 and 610 (M30, M20), and Shimano CUES (H50). Carbon models use Orbea’s Oquo carbon wheels, made near their factory in the Basque Country. Tyre clearance runs to 50mm with 45mm Vittoria Terreno Dry gravel tyres standard on mid-range and above.

Who Rides the Orbea Denna?

We asked Alex, one of our specialists who rides road and mountain bikes at a high level, what he thinks of the Denna. His answer cuts to the heart of it: the modern geometry makes it quick and stable, it’s still comfortable on those really long rides, and he appreciates the thought that has gone into Orbea’s tune on the Shimano motor — making it adaptable to different riders and completely different ride situations. Tom’s take is more direct: it’s very fast, even past the power cutout, and a very strong climber thanks to the pedalling platform and motor assist.

The Denna’s customer base consistently turns out to be experienced road cyclists who love high-end bikes and want something special that genuinely enthuses them about continuing to ride. These are not people who gave up on cycling and want a motor to do the work — they are people who want to ride further, faster, and more often, and who want a bike that reflects their standards. The Denna delivers exactly that.

Riding Gravel and Road E-Bikes Around Brisbane and SE QLD

SE QLD is genuinely excellent gravel and road riding country, and the Denna is built for exactly this kind of terrain. Sam’s recommended route for this bike: out through Samford Valley to Dayboro, through Lacey’s Creek and then up along Range Road through D’Aguilar National Park to the Gantry, back via Mt Mee to Dayboro and home to Samford. It is a perfect Denna ride — sealed road, gravel, and real climbing mixed together in a loop that covers terrain the Denna handles with confidence.

Further out, the country roads around Crows Nest are a favourite for longer days, and Tenterfield has a growing network of gravel trails worth the drive for a dedicated riding weekend. For a more accessible first ride with the Denna, the Brisbane Valley Rail Trail — 161km of mostly flat rail trail through the Brisbane Valley — is a natural choice. The Mt Nebo and Mt Glorious loop in the D’Aguilar Range is another: 111km of sweeping descents and challenging climbs with café stops at Mt Nebo and Mt Glorious Village.

This is a large range and not all Denna models are currently listed on our website. As a Platinum Orbea dealer, we can custom order any Denna or Gain model — including spec levels not listed online — with factory-fresh delivery to our Milton store. New Denna and Gain test models are arriving in 2027.
