Giant Reign Advanced E+ 0 Bike
Climb like it's flat and descend like a demon on the Giant Reign Advanced E+ 0.
This is a carbon full-suspension e-enduro bike for the aggressive trail rider who wants more laps and bigger days. The Reign Advanced E+ 0 delivers long-travel confidence with a powerful pedal-assist motor, so the fire-road grinds up into the Santa Monica Mountains become the warm-up, not the workout. Point it downhill and it comes alive.
It's right for you if:
You want to double your descents by cutting the climb time.
You ride steep, technical terrain and need real suspension travel.
You want a premium carbon e-MTB you will not outgrow.
Why you'll love it:
Long-travel suspension soaks up rock and root so you stay in control at speed.
Strong pedal assist means more laps in the same amount of daylight.
The carbon frame keeps weight down for lively, planted handling.
Powerful brakes give you confident control on steep, loose descents.
The tech you get: Advanced-grade composite frame, roughly 160mm-travel enduro suspension, Giant SyncDrive Pro motor (up to about 85Nm) with a large EnergyPak battery (around 800Wh), Class 1 pedal-assist to 20mph, and 29-inch wheels. Real-world range varies with terrain, rider weight, and assist level, so expect big rides on a charge but plan longer epics accordingly.

Highlights
Maestro Suspension, 170mm
The reworked Maestro linkage gives 170mm of rear travel with a bottomless, progressive feel, backed by a 180mm fork. It stays composed through rock gardens and soaks up big hits so you can charge the steep stuff with confidence.
SyncDrive Pro 3 Motor
The 48V SyncDrive Pro 3 pushes 90Nm of torque and up to 800W of peak power, with six sensors reading your effort and the terrain. It delivers punchy, natural assist right when you need it on a tough climb.
EnergyPak 560 Battery
The integrated 560Wh battery charges to 80 percent in about two hours and is rated for up to 2,300 charge cycles. That is long range on the trail and a battery built to last for years.
SRAM Transmission AXS
Wireless SRAM Eagle Transmission shifts cleanly under full power and a heavy load, exactly what an e-MTB demands. No fussing with a front derailleur, just a wide, reliable gear range.
Titanium Skid Plate & Bash Guard
A titanium skid plate twice as strong as aluminum, full down-tube protection, and an MRP bash guard with an elastomer damper shield the frame and drivetrain. Send it into rough terrain without babying the bike.
SRAM Maven & Fox Factory
Four-piston SRAM Maven brakes on 200mm rotors haul this bike down hard, while a Fox 38 Factory fork and Transfer dropper keep the front planted and the saddle out of the way. Serious control for serious descents.
