Giant Reign Advanced E+ 2 2026 Electric Bike

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. Giant 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.

Features

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.

Technologies

• E System: E+ System combines electric power with human power to produce a smart, natural and powerful E-bike riding experience. It's an integrated group of technologies that includes Giant's RideControl control units, EnergyPak battery systems and SyncDrive motors. For more information, check out the link below.
• Smart Assist: All SyncDrive motors have Smart Assist technology, which adjusts the support to match the rider's needs. By using information from multiple sensors, both rider input and terrain feedback are used to determine the optimal amount of pedaling assistance. SyncDrive is the only E-Bike system that utilizes both rider input and terrain feedback. It gives you a smooth, natural riding experience with ample power when you need it, while also conserving power when you don't need as much.
• Flip Chip Maestro 3: This all-new technology allows riders to quickly adjust the geometry and choose a rear wheel size (29-inch or 27.5-inch) for their riding style and terrain. It's available on select Maestro-equipped mountain bikes. The adjustment affects head tube and seat tube angles, bottom bracket height, and rear-wheel size using eccentric flip chip hardware located on the upper rocker arm of the rear suspension.
• Maestro Suspension Technology: Four strategically positioned pivot points and two linkages all work together to create a single floating pivot for the most active, efficient and independent suspension system on the trail.
• Advanced Composite Technology: Giant's High Performance Grade raw carbon material is used to produce this custom frame material in Giant's own composite factory with a high stiffness-to-weight ratio. The front triangle of these framesets is assembled and molded as one continuous piece in a proprietary manufacturing process called Modified Monocoque Construction.
• Ride Control Ergo 4: The new RideControl Ergo 4 builds on the previous generation Ergo 3 with a sleek, grip-integrated 3-button remote control unit. It blends seamlessly with your handlebar and grips and has a larger, more concave shape and improved tactile feedback.
• Energypak 560: Integrated 560Wh battery pack powers a 48-volt system that produces more power with less heat and stress on the battery cells. Exceptionally durable, it delivers up to 2300 full charge cycles-more than any other E-bike battery-and recharges rapidly, reaching 80% battery capacity in as little as two hours.
• Energy Pak Plus 280: This range extender can boost total capacity by 280Wh. This gives you the choice-lighter weight for everyday rides or longer range for epic ride days.
• Sync Drive Pro 3: Powerful new 48-volt system delivers up to 800 watts of peak power while producing less heat and motor stress-improving efficiency to give you more peak power for longer. You can tune and adjust torque and support levels to match your ride. Choose full power for steep climbs, or dial it back to save energy on long rides.
