Giant Reign Advanced E+ 1 Electric Full Suspension Mountain Bike 2026 in Mercury/Carbon Smoke

Season:2026

Brand:Giant

Code:6461001Smoke

The Giant Reign Advanced E+ 1 is engineered for riders who demand maximum confidence and control on the most technical descents. Its Advanced-grade composite frame with 170mm of Maestro rear travel and a 180mm Fox 38 Performance Elite fork delivers precision and stability on rugged trails.

The latest 48V SyncDrive Pro 3 motor produces 90Nm of torque and 800W peak power, while the EnergyPak Smart 560Wh battery ensures consistent range and reliability. Combined with SRAM Eagle Transmission shifting, TRP DH-R EVO brakes, and mixed wheel sizing, this E-MTB is built to dominate every climb and descent with power and composure.

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.

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.

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.
