Giant Reign Advanced E+2 Bike
The Giant Reign Advanced E+2 lets you earn twice the descents in half the time.
The Reign Advanced E+2 is a long-travel electric enduro bike for riders who want to attack the steepest, gnarliest lines and still lap them all day. Giant's SyncDrive motor flattens the fire-road climbs, so you spend your energy where it counts, bombing the technical trails in the Santa Monica Mountains.
It's right for you if:
You love aggressive downhill and enduro riding but hate the shuttle wait.
You want more laps and bigger days without burning out on the climbs.
You ride steep, technical terrain and need serious travel and control.
Why you'll love it:
Big-torque motor assist turns brutal climbs into quick transfers between descents.
Long-travel Maestro suspension keeps the wheels planted through rocks and chatter.
The Advanced-grade carbon front triangle cuts weight and sharpens handling.
A large-capacity battery means more climbing before you think about charging.
The tech you get: an Advanced carbon composite frame, Giant's high-torque SyncDrive motor, a large-capacity EnergyPak battery, Class 1 pedal-assist (up to 20 mph), and long-travel Maestro suspension on 29-inch wheels. Real-world range varies with terrain, rider weight, and assist level, expect less on big climbing days.

Highlights
Built to Descend
This is an enduro e-bike tuned for the way down. 170mm of Maestro travel out back and a 180mm RockShox Zeb up front soak up chunk, drops, and root gardens so you can point it and hold speed.
SyncDrive Pro 3 Motor
Giant's 48V drive puts out 90Nm of torque and up to 800W of peak power. Translation: it climbs the ugly stuff so you get more laps and reach trails you'd never pedal to on a regular bike.
EnergyPak Smart 560Wh
The integrated 560Wh battery carries you through long days in the hills, and when you want more, it takes an optional 280Wh range extender for the biggest rides.
SLX 4-Piston Brakes
Four-piston Shimano SLX stoppers on 220mm rotors give you the control to run into corners hot and shed speed late. On a heavy, fast e-enduro bike, that braking power is what keeps you confident.
Aggressive Maxxis Rubber
A Maxxis Assegai up front and Minion DHR II out back is the grip-and-brake combo enduro riders trust. Both are tubeless-ready, so you can run lower pressures for traction without pinch flats.
Protected Where It Counts
A titanium skid plate and MRP bash-guard shield the frame and drive from rock strikes. This bike is meant to take hits, not baby the trail.
