Ride Beyond Limits – Now Available at The Rolling Fix, Liverpool
Meet the 2026 Mondraker Dune RR Electric Mountain Bike in striking Obsidian Grey — where world-class engineering meets raw trail power. Designed for riders who demand precision, control, and performance on every descent, the Dune RR is a mullet-configured enduro e-MTB built to dominate the toughest terrain around Liverpool, North Wales, and beyond.
At its heart is Mondraker’s Stealth Air Full Carbon Frame, offering 165mm of rear travel through the updated Zero Suspension System for unrivalled traction and stability. The Forward Geometry design ensures perfect handling whether you’re carving through the Peak District’s rocky trails or tackling fast, flowing singletrack closer to home.
Powering your adventure is the ultra-efficient Bosch Performance Line SX Gen4 Smart System motor, delivering smooth, responsive pedal assistance up to 25km/h. Paired with a Bosch Compact Powertube 400Wh battery, this integrated, non-removable system keeps the weight low and the aesthetics clean — all while providing the perfect balance between power and endurance.
Up front, the Fox Podium 29 GRIPX2 Factory Kashima fork with 170mm of travel and the Fox DHX2 Factory Kashima rear shock ensure total control on steep, technical descents. SRAM’s Maven Bronze 4-piston brakes with massive 200mm rotors provide unbeatable stopping power, while the Sram X0 Eagle AXS T-Type drivetrain delivers crisp, wireless shifting with 12-speed precision.
Rounding out the build are e*thirteen Grappler Flux rims, Maxxis Assegai and Minion DHR II tyres, and a premium cockpit from Onoff Components — including a carbon handlebar and adjustable dropper post for total command over any terrain.
