Mondraker Dune R
The Full Scoop on Mondraker Dune R
The 2026 Mondraker Dune R is the ultimate lightweight superenduro eMTB — a full carbon machine built for riders who want downhill capability with trail-weight agility. Mondraker's world-class platform delivers the most progressive kinematics, aggressive geometry, and race-bred engineering in the light e-MTB category.
Built around a Stealth Air Full Carbon frame with the patented Zero Suspension System and Forward Geometry, the Dune R delivers 165mm of rear travel paired with a 170mm RockShox ZEB Select Charger RC 29 fork. The mullet wheel configuration (29" front / 27.5" rear) gives you the rollover speed up front with the agility and acceleration out back.
Powered by the Bosch Performance Line SX Gen4 Smart System motor with a compact 400Wh internal Powertube battery, the Dune R delivers 600W peak power and up to 400% pedaling support via the eMTB+ mode — all at a remarkably low 44.8 lbs. Over-the-air updates via the Bosch eBike Flow App keep the motor firmware current with the latest performance optimizations.
