Giant Reign E+ 2 Bike
All the descent, twice the laps: the Giant Reign E+ 2 is a full-power enduro e-bike.
The Reign E+ 2 is a big-travel electric enduro bike for riders who want to earn more descents in less time. The Giant SyncDrive Pro motor hauls you up so you can session the good stuff. Shuttle yourself up the fire roads above the Valley and drop the technical lines again and again.
It's right for you if:
You want maximum descents per ride without a shuttle vehicle
You ride steep, technical enduro terrain
You want full-power assist and big battery range
You'd like Steve and Brian to size and dial it in person
Why you'll love it:
SyncDrive Pro motor delivers strong, natural power that flattens the steepest climbs
Large-capacity EnergyPak battery gives you real range for big backcountry days
160mm Maestro suspension keeps you composed on rough descents
Powerful hydraulic disc brakes control the extra speed and weight
Class 1 pedal-assist keeps you legal on most local trails
The tech you get: an ALUXX aluminum frame, a Giant SyncDrive Pro motor (85Nm), an EnergyPak battery, Class 1 pedal-assist, Maestro suspension with about 160mm of rear travel, hydraulic disc brakes, and a dropper post. Honest note: real-world range varies with terrain, rider weight, and assist mode.
