The foundation of the DUNE is a Stealth Air Carbon frame weighing in at 2650 grams, combined with the power and light weight of Bosch’s latest offering, the Performance SX. The frame showcases our Updated Zero Suspension and offers 165mm of rear-wheel travel and Forward Geometry specifically tuned for this long-travel hard-hitting light ebike.

DUNE R: THE ENTRY LEVEL BUILD

The entry level DUNE R gives up little to its more expensive siblings. A 170mm FOX 38 Float 3P Performance Grip fork keeps the front wheel in check while a Fox Float X Performance EVOL shock tames things at the back, SRAM supplies the GX Eagle rear mech and E.13 their E*Spec Plus cranks, ONOFF provide the Pija dropper post, SRAM the DB8 brakes and e*thirteen Grappler Core wheels with 30mm wide aluminium rims round things out.
