Product Details
The Orbea Denna M20i gravel bike is built for riders who demand power, traction, and endurance across all terrains. Whether tackling steep climbs, loose gravel, or long-distance adventures, this bike delivers a seamless yet thrilling ride with generous tire clearance, a smooth-riding carbon frame, and a motor optimized for gravel.
At its core, the Shimano EP801 RS GEN2 RC Motor—enhanced with Orbea’s exclusive Rider Synergy (RS) firmware—provides natural, responsive assistance without overpowering the ride. With 85Nm of torque and RC (Road Control) tuning, it is purpose-built for gravel and road riding, ensuring smooth and efficient performance on varied terrain.
The Orbea 420Wh battery delivers up to 3,500 meters (11,000 feet) of climbing, offering exceptional energy density while keeping the overall weight remarkably low.
A longer top tube and shorter stem provide precise handling and stability, while strategically designed frame absorption points flex to minimize vibrations, ensuring a smooth and controlled ride without sacrificing efficiency.
