If you’re looking to push the boundaries of your riding — blending tarmac, gravel, dirt roads and back-country routes — the Orbea Denna is a game-changer. In this post, we’ll dive into exactly why the Denna is a standout in the growing gravel-ebike category, walk through its specs and features, and highlight why Cycle Lab is one of the best places in South Africa to experience and own one.
Gravel cycling has exploded in popularity because it offers freedom — less traffic, more exploration, and a mix of surfaces. But pure gravel bikes have limits: long climbs, headwinds, or extended rides can push many riders past their threshold. Gravel e-bikes like the Orbea Denna allow you to:
Orbea, the Basque bike maker known for its performance road and MTB lines, has now launched a purpose-built gravel e-bike: the Denna. Rather than modifying an existing road or gravel frame, Orbea designed it from the ground up with gravel-specific geometry, comfort, and control.
The Denna uses the Shimano EP801 RS mid-drive motor, tuned by Orbea’s RS Gen2 firmware for a natural and responsive feel. It delivers up to 85 Nm of torque — plenty for steep gravel climbs. Riders can choose between two assist profiles:
The clever integration of the left-hand Di2 shifter allows riders to switch assist modes seamlessly without extra controls cluttering the handlebar.
The integrated 420 Wh battery offers impressive climbing and range, with the ability to gain up to 3,500 metres of elevation on a single charge. For longer rides, a 210 Wh range extender — shaped like a water bottle — can be added without affecting the bike’s balance or handling.
The Denna’s OMR carbon frame is engineered for stiffness, comfort, and vibration absorption. Vertical flex zones smooth out rough terrain, while lateral stiffness ensures efficient power transfer. It accommodates tires up to 50c, giving riders flexibility to switch between smooth gravel or more rugged backroads.
Geometry tweaks such as a lower bottom bracket and optimized chainstay lengths deliver stability, confidence, and control across all frame sizes.
The Orbea Denna comes in several builds (M30, M20, M10i, etc.), each with high-end groupsets and gravel-ready components. For instance, the Denna M30 version includes:
Higher-tier models upgrade to Ultegra, Deore XT Di2, or SRAM options depending on specification and availability.
Weighing around 13.9 kg (for the M20i), the Denna is among the lightest e-gravel bikes in its category. Its geometry prioritizes stability and comfort, making it ideal for long-distance adventures and rough terrain rather than aggressive race positions.
The Orbea Denna is more than just another e-gravel bike — it’s a statement that you don’t have to choose between speed, torque, or adventure. With its refined geometry, powerful motor, and customizable options, it’s the perfect partner for South African gravel roads and beyond.

Sorry, but you don't know what you're talking about. It does not have the 85 Nm that the motor is capable of doing, because Orbea, in their dumbass infinite wisdom, stepped it down to 60.
