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.
DOMINANT ON DESCENTS
Featuring a modified Maestro suspension system with a new integrated lower link and 170mm of rear travel paired with a 180mm fork, this is best descending E-bike ever from Giant. Maestro’s floating pivot design means it’s always active and efficient under pedaling. Its progressive leverage curve makes the rear shock is easy to compress at the top of the stroke and super-supportive near the end range, producing a plush, bottomless feel that uses every bit of its travel. The result is unmatched confidence and control for big hits, steep drops and technical rock gardens.
LIGHTWEIGHT YET POWERFUL
Upgrading from a 36-volt to 48-volt system results in better performance with reduced heat and energy loss. With 90Nm of torque and 800 watts of peak power, the new SyncDrive Pro 3 motor lets you sustain a high torque level, even at higher pedaling cadences—so you feel powerful, consistent support in any riding situation The added power combined with a lighter composite frame and overall weight of just 22.3kg (size medium) means the Reign E+ Advanced packs a punch when you need it most. And the 48-volt system also produces less stress on the EnergyPak 560 battery, which has a nearly endless lifespan of up to 2300 charge cycles.
PREMIUM PROTECTION
Designed to shred hard and take a beating, the Reign Advanced E+ features a tough, dual-density battery cover that doubles as a full-length protector on the underside of the down tube—perfect for chairlifts, trailers or pickup truck shuttles. A new integrated skid plate protects the motor with corrosion resistant titanium that’s twice as strong as aluminum. And with less friction, the skid plate also helps keep you from getting hung up on rocks, roots, or other obstacles. Finally, a unique MRP active bash-guard, with an elastomer damper and suspended design, gives you unmatched chain and chainring protection.
