Giant Reign Advanced E+ 1: built for enduro
The Giant Reign Advanced E+ 1 is a full-suspension e-MTB developed for riders looking for a bike capable of handling steep descents, technical terrain and big impacts with confidence and stability.
Its Advanced Composite frame integrates the Maestro suspension system with 170 mm of rear travel, paired with a 180 mm fork. The 90 Nm SyncDrive Pro 3 motor and 48 V electrical system complete a platform designed for demanding enduro riding.
Maestro suspension with 170 mm of travel
The Maestro suspension system is one of the key features of the Reign Advanced E+. Its floating pivot design uses four strategically positioned pivot points and two linkages to keep the suspension active while pedalling and independent from braking forces.
The setup provides 170 mm of rear travel with a progressive compression curve. The suspension remains sensitive through the initial part of the travel while becoming increasingly supportive towards the end of the stroke.
Up front, the bike features a Fox 38 Performance Elite 180 mm fork with GRIP X2 damper, creating a suspension platform designed for technical trails, steep descents and demanding impacts.
SyncDrive Pro 3 motor with 90 Nm of torque
The new Giant SyncDrive Pro 3 uses a 48 V electrical system and delivers up to 90 Nm of torque, with a declared peak power output of 800 W.
The system allows torque and assistance levels to be adjusted according to your riding style and the terrain. You can use higher assistance on steep climbs or reduce the support to conserve energy on longer rides.
The European version provides pedal assistance up to 25 km/h.
PedalPlus 6-Sensor and Smart Assist
Giant's PedalPlus 6-Sensor technology monitors parameters including pedalling power, speed, cadence, terrain gradient and acceleration to determine the appropriate level of motor assistance.
With Smart Assist, the system can automatically adjust assistance according to riding conditions, helping provide a more natural and balanced riding experience without constant manual adjustments.
EnergyPak Smart 560 Wh battery
The Giant EnergyPak Smart 560 Wh battery is integrated into the frame and powers the 48 V SyncDrive Pro 3 system.
Giant states up to 2,300 full charge cycles and charging up to 80% capacity in approximately two hours when using the 4 A EnergyPak Smart charger.
For this configuration, Giant indicates an approximate range between 45 and 160 km, depending on riding conditions. Temperature, wind, tyre pressure and profile, terrain, rider weight, acceleration and assistance level can all have a significant effect on actual range.
Advanced Composite: a frame designed for enduro
The main frame and rear swingarm are made from Advanced Composite, using high-performance carbon fibre and Giant's custom resin technology.
The modified monocoque construction is designed to combine a lightweight, stiff and responsive structure with effective vibration absorption.
The Reign Advanced E+ also features a three-position adjustable frame geometry using a flip chip, allowing the rider to modify the head tube angle, seat tube angle and bottom bracket height according to riding style and terrain.
Adjustable reach
A second three-position flip chip in the headset allows the cockpit reach to be adjusted between short, medium and long positions in 5 mm increments.
This provides additional possibilities for adapting riding position and handling to the rider and the type of terrain being tackled.
Premium motor and frame protection
The Reign Advanced E+ 1 is designed for particularly demanding riding, including the impacts and obstacles encountered on technical enduro trails.
The underside of the motor is protected by an integrated titanium skid plate, while an MRP bash guard with elastomer damper protects the chain and chainring area from impacts with rocks, roots and other obstacles.
The dedicated downtube and battery protection is also designed to protect the bike during transport on chairlifts, trailers and pickup trucks.
MX setup: 29" front and 27.5" rear
The Reign Advanced E+ 1 uses an MX wheel configuration, with a 29" front wheel and a 27.5" rear wheel.
This combination pairs the stability and obstacle-clearing ability of a larger front wheel with the more compact rear wheel, while the Flip Chip - Maestro 3 system also allows the rear wheel size and frame geometry to be adjusted.
The Giant e-TRA rims feature a 30 mm internal width, Hookless construction and Hollow Side-Wall Design, developed to improve durability and protection against impacts.
Maxxis tyres for enduro riding
The bike comes equipped with Maxxis tyres designed for demanding trail and enduro use:
- Front: Maxxis Assegai 29 x 2.5", Tubeless, EXO+, 3C MaxxGrip
- Rear: Maxxis Minion DHR II 27.5 x 2.4" WT, Tubeless, DoubleDown, 3C MaxxGrip
The combination is designed around the different demands placed on the front and rear tyres, with a setup focused on control and traction on technical trails.
SRAM Eagle 90 Transmission 12-speed drivetrain
The SRAM Eagle 90 Transmission drivetrain offers 12 gears and a 10-52T cassette, providing a wide range for demanding climbs and technical terrain.
- Shifter: SRAM Eagle 90 Transmission Single Click
- Rear derailleur: SRAM 90 Eagle Transmission
- Cassette: SRAM Eagle Transmission 10-52T, 12-speed
- Chain: SRAM 70 Eagle Transmission Flattop Powerlink, 12-speed

TRP DH-R EVO four-piston brakes
To manage speed on demanding trails, the Reign Advanced E+ 1 is equipped with TRP DH-R EVO hydraulic disc brakes featuring four-piston calipers.
220 mm rotors front and rear complete the braking system, providing a setup designed for enduro riding and steep descents.
Giant Contact Switch dropper post
The Giant Contact Switch is a 30.9 mm dropper post with MMX remote. Drop travel varies according to frame size:
- S: 110-140 mm
- M: 140-170 mm
- L/XL: 170-200 mm
Being able to quickly lower the saddle on descents and technical sections gives the rider greater freedom of movement and more control over the bike.
RideControl GO Lux and RideControl Ergo 4
The RideControl GO Lux system integrates a colour display into the top tube. It shows battery status, remaining range and front and rear tyre pressure, together with key riding data such as speed, time, distance and cadence.
The RideControl Ergo 4 remote uses three buttons and integrates with the handlebar and grips, allowing the assistance system to be controlled directly from the cockpit.
Aegis E-Lock and Apple Find My
The Reign Advanced E+ integrates the Aegis E-Lock security system, allowing the motor assistance to be disabled and the bike to be digitally locked through the app, remote or PIN.
If the bike is moved without authorisation, an audible alarm can be triggered. The advanced security system also supports Apple Find My, allowing you to locate the e-bike remotely and receive notifications if its location changes.
