Whether you’re tackling steep natural descents, technical bike park lines or all-day mountain adventures, the Reign Advanced E+ delivers exceptional confidence, control and power.
New SyncDrive Pro 3 Motor – More Power, More Control
At the heart of the Reign Advanced E+ sits Giant’s latest SyncDrive Pro 3 motor system.
Delivering up to 90Nm of torque and 800 watts of peak power, the new 48-volt system provides smooth, natural assistance while offering the punch needed to conquer the steepest climbs.
The advanced PedalPlus six-sensor technology constantly monitors rider input, cadence, speed and terrain gradient, ensuring support feels intuitive rather than intrusive. Whether you’re grinding up a technical climb or sprinting out of a corner, power delivery remains smooth and predictable.
The system can also be fully customised through the Giant RideControl app, allowing riders to tune support levels and motor behaviour to suit their riding style.

Advanced Composite Frame Technology
The Reign Advanced E+ uses Giant’s premium Advanced Composite construction for both the front triangle and rear swingarm.
Manufactured in Giant’s own carbon facility using high-performance carbon fibre and proprietary resin systems, the frame delivers an exceptional balance of stiffness, strength and weight savings.
The result is a chassis that remains precise and responsive through rough terrain while helping keep overall bike weight under control.
Additional protection features including a titanium skid plate, integrated frame armour and an advanced bash guard with elastomer damping ensure the bike is ready for aggressive riding in demanding environments.
170mm Maestro Suspension Performance
Giant’s renowned Maestro suspension platform continues to be one of the most effective suspension systems available.
With 170mm of rear wheel travel paired to a 180mm fork, the Reign Advanced E+ delivers exceptional small bump sensitivity, mid-stroke support and bottom-out resistance.
The floating pivot design allows the suspension to remain active under braking and pedalling, providing maximum traction when climbing and outstanding control when descending.
For riders seeking a true enduro-focused electric mountain bike, the Reign Advanced E+ offers the confidence and capability needed to tackle the roughest trails with speed.
Fully Adjustable Geometry
One of the standout features of the Reign Advanced E+ is its highly adjustable geometry.
The Maestro flip chip system allows riders to choose between three geometry positions:
This enables fine-tuning of head angle, seat angle and bottom bracket height to suit local terrain and personal preferences.
A second headset flip chip allows riders to adjust cockpit reach in three positions, offering a highly personalised fit without compromising handling characteristics.
The result is one of the most adaptable electric mountain bikes currently available.

Extended Range for Bigger Adventures
Every Reign Advanced E+ model comes equipped with Giant’s latest EnergyPak Smart 560 battery.
The 560Wh battery has been developed specifically around the new 48-volt architecture, providing improved efficiency, reduced heat generation and exceptional durability.
For riders wanting even greater range, the optional EnergyPak Plus 280 range extender increases total battery capacity to 840Wh, making epic mountain days and uplift-free adventures easier than ever.
The battery system is capable of reaching 80% charge in approximately two hours, helping maximise ride time between adventures.
Smart Technology and Security
The Reign Advanced E+ integrates Giant’s latest RideControl GO Lux display and control system.
The full-colour display provides clear access to:
- Speed
- Distance
- Cadence
- Battery status
- Remaining range
- Front and rear tyre pressure
Security has also been significantly upgraded.
The new AEGIS E-Lock system allows riders to digitally lock the motor via smartphone, remote or PIN code. If the bike is moved without authorisation, an audible alarm is activated.
In addition, AEGIS Find My integration allows riders to locate their bike through Apple’s Find My network, providing additional peace of mind when travelling or stopping during rides.
