Everything about the new Reign Advanced E+ is designed to make it the best descending E-MTB ever. From the bottomless feeling Maestro suspension with 170mm of rear travel (and a 180mm fork) to the punchy new SyncDrive Pro 3 motor and its lightweight, stiff and ultra-adjustable composite frame. We added a titanium skid plate, robust frame protection, and an innovative bash-guard with an elastomer damper—so you can send it with confidence on the most rugged, technical terrain.
