The Mondraker Dusty R is built for riders who want the speed and efficiency of a gravel bike combined with the smooth assistance of a lightweight e-bike system. Designed around Mondraker’s Stealth Air Carbon frame and powered by the discreet Mahle X20 motor, the Dusty R delivers a natural ride feel with added support for longer adventures, faster rides, and bigger climbs.
Whether you're tackling mixed terrain, endurance rides, or fast-paced gravel loops, the lightweight carbon chassis and Forward Geometry-inspired handling provide stability and comfort without sacrificing responsiveness. The integrated Mahle X20 system keeps weight low while delivering smooth and intuitive assistance when the terrain turns demanding.
A SRAM Apex AXS wireless drivetrain paired with a GX Eagle AXS rear derailleur gives the Dusty R a huge gear range and clean wireless shifting performance, while Mavic Allroad wheels and wide 700x45c Maxxis Rambler tyres provide grip, comfort, and confidence across rough gravel tracks and back roads alike.
With its sleek integrated design, premium carbon construction, and lightweight electric assistance, the Dusty R is ready to redefine what’s possible on every gravel ride.
