Product Details
The Orbea Denna M31e 20mph 2025 redefines what's possible on an electric gravel bike, empowering riders to chase bigger rides, bolder routes, and longer adventures. Whether it's the open road, rough doubletrack, or winding fire roads, the Denna M31e delivers a ride that feels natural, capable, and endlessly fun.
Powered by the Shimano EP801 motor and paired with a sleek 420Wh internal battery, the Denna M31e balances torque and range with impressive efficiency. The motor’s intuitive responsiveness feels perfectly matched to each pedal stroke, while the centered battery placement maintains stable handling across all terrain. Orbea’s purpose-built gravel geometry keeps things agile yet planted, with a longer wheelbase for confidence at speed, a lower bottom bracket for stability, and fine-tuned frame sizing for comfort over big mileage.
The frame’s engineered compliance helps absorb trail chatter without dulling your connection to the terrain. Up front, the carbon fork’s long legs and stiff crown offer precision steering and reliable comfort. With clearance for up to 700x50C tires, the Denna M31e lets you choose between fast-rolling rubber or high-volume tires that smooth out the rowdiest gravel and backcountry tracks.
With SRAM’s wireless Rival XPLR eTAP AXS drivetrain, fast, clean shifting is always at your fingertips, while the Oquo RC25TEAM wheels add a responsive, lightweight feel on long climbs and loose descents. Whether you're riding deep into the hills or linking together remote routes, the Denna M31e is made for riders who believe the best roads are the ones that lead to the unknown.
