The Orbea Denna M31e is the most technologically advanced model in the Denna lineup — a premium electric gravel bike built around a fully wireless SRAM Rival XPLR AXS electronic groupset for riders who want cable-free simplicity and precision on every gravel adventure. Built around the Orbea Denna frame with 12 mm thru-axle rear and internal cable routing, paired with an Orbea Denna OMR full carbon ICR fork with 12x100 mm thru-axle, the M31e delivers a stiff, precise, and refined ride platform engineered for serious gravel performance. The FSA 1-1/2" integrated aluminium cup headset and clean internal cable routing complete a frameset built for both performance and aesthetics.


Power is provided by the Shimano EP801 motor — more powerful and refined than the EP600 — with Shimano Steps EM600 cranks and a 44T alloy EP8 chainring, backed by an Orbea Internal 420 Wh battery for capable range on demanding gravel rides. The EN600-L remote keeps motor management simple and accessible, while the Orbea eBike chainguide and SRAM Rival 12-13 speed chain ensure clean, efficient power transfer across every surface. Charging is handled by the Orbea 2nd Generation eBike Smart Charger.


The M31e sets itself apart with a full SRAM Rival XPLR AXS wireless electronic groupset — a SRAM XG-1351 XPLR 10-46T 13-speed cassette and SRAM Rival XPLR AXS 13-speed rear derailleur delivering effortless, cable-free gear changes at the touch of a button, purpose-built for the demands of gravel riding. Braking is handled by SRAM Rival AXS hydraulic disc brakes for powerful, consistent stopping power in all weather and terrain conditions. The cockpit features an OC Gravel GR10 carbon handlebar with 70 mm reach and 110 mm drop — lightweight, stiff, and gravel-specific — paired with an OC Road Performance RP10 -8° stem.


Vittoria Terreno Dry Gravel G2.0 TLR 700x45c tyres deliver confident grip and rolling efficiency on mixed gravel and road terrain, mounted on Oquo Road Control RC30TEAM wheels — a wider, stiffer, and more capable wheelset than the RC25PRO — with Orbea hollow front and solid inner threaded rear thru-axles for a fast, lightweight, and responsive rolling package. The Selle San Marco Shortfit 2.0 Start Up Off Road Xsilite saddle, OC Performance XP10 carbon 27.2 mm seatpost with 0 mm setback, and Orbea anti-slippery shock-proof handlebar tape complete a wireless, performance-focused gravel build that leads the Denna range.
