2025 GIant Reign Advanced E+ 1
$4,300.00
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.
Key Performance Features
Built for Ultimate Descending Control
This advanced e-mountain bike is engineered to dominate aggressive descents. It features a redesigned Maestro suspension system with an integrated lower link, delivering 170mm of rear travel paired with a 180mm suspension fork. This setup creates one of the most capable descending e-bikes Giant has ever produced.
The floating pivot design of the Maestro system keeps the suspension active and efficient while pedaling. Its progressive leverage curve allows the rear shock to remain sensitive at the beginning of the stroke while providing strong support toward the end of the travel. The result is a smooth, controlled ride that absorbs large impacts with ease, giving riders maximum confidence on steep drops, technical rock gardens, and high-speed trails.
Lightweight Yet Powerful Performance
The bike features a powerful 48-volt system, upgraded from the previous 36-volt platform. This improvement delivers higher efficiency, reduced heat, and less energy loss during demanding rides.
Powered by the SyncDrive Pro 3 motor, the system produces 90Nm of torque and up to 800 watts of peak power. It maintains strong torque even at higher pedaling cadences, providing smooth and consistent assistance across a wide range of riding conditions.
Despite its impressive power, the bike remains lightweight thanks to its advanced composite frame, with a total weight of approximately 22.3kg (size medium). The efficient 48-volt design also places less strain on the EnergyPak 560 battery, extending its lifespan to up to 2,300 charge cycles.
Built-In Protection for Aggressive Riding
Designed to handle demanding terrain, the bike includes several premium protection features. A dual-density battery cover protects the integrated battery while also acting as a full-length down-tube guard—ideal for transport on chairlifts, trailers, or truck tailgates.
The motor is protected by a new integrated skid plate made from corrosion-resistant titanium, which is significantly stronger than aluminum. Its smooth surface reduces friction, helping the bike glide over rocks, roots, and trail obstacles without getting caught.
To further protect drivetrain components, the bike is equipped with an MRP active bash guard featuring an elastomer damper and suspended design. This system provides exceptional protection for the chain and chainring while maintaining smooth and reliable performance on rough trails.

WeightThe most accurate way to determine any bike’s weight is to have your local dealer weigh it for you. Many brands strive to list the lowest possible weight, but in reality weight can vary based on size, finish, hardware and accessories. All our bikes are designed for best-in-class weight and ride quality.
