Despite the smaller battery, the SyncDrive Pro 3 motor at the heart of the Giant Reign Advanced E+ betters its predecessor with 800 W peak power, and a modest increase in maximum torque to 90 Nm.

Giant Bicycles debuts the new Reign SE at Crankworx Whistler, featuring a burly build for bike park or gravity riding.

A terrific suspension setup, and a highly-capable motor highlight an overall great ride experience. Our time testing and reviewing the Giant Reign E+ Pro 2 was eye-opening. There was a lot we already knew going into it: Giant knows what its doing with MTBs and produces sound products, Yamaha makes good motors, and a lot
The suspension makes downhill riding and jumping a blast! The combo of the Maestro linkage, Rockshox Zeb, and Fox Float X made for an exhilarating experience.
The Giant-tuned Yamaha motor is fantastic. It shines in low cadence pedal situations, but just makes the bike highly capable in most any setting.
The geo of the bike is very stable. It’s a fairly slacked out setup, but it has a longer chainstay that helps keep the bike feeling steady when going down hill at speed.
Lot’s of control for handling technical terrain with the Maxxis mullet setup. The tires provide nice traction in various settings, yet rolled with great efficiency and speed.
We liked the minimal LED interface, and the Giant companion app allows for ride customization for tuning the motor output to your preference.
The Flip Chip tech can change up the geo. We enjoyed steepening the headtube when we took it on trails that had more switchbacks and tighter cornering. Optionality is never a bad thing!
The PAS control buttons are hard very subtle, but they are hard to discern on the fly. A more tactile and distinct pad would be nice.
Not so much a con as an FYI, the motor feels twitchy when trackstanding. It can be dialed back in the app, but we learned to enjoy the benefits of quick engagement.

Lots of options, including mullet with the new, highly adjustable Giant Reign.
May 2023 · Blake Nielsen
Giant’s engineering team completely overhauled the Reign Advanced for 2023 with a frame redesign that has now moved away from the somewhat ‘freeride’ style geometry numbers that the Reign has adopted in the past, and instead they set out to create a purebred, no-compromise enduro race bike! Reviewer // Blake Nielsen Photos // Matt Staggs Let’s get straight to the point, does it seem like they’ve hit the brief and how much ‘speedier’ is the bike now compared the previous […]

Featuring a new frame with more travel and mullet compatibility, the new 2023 Giant Reign is a big step up over its predecessor.
Incredibly calm and composed on rough terrain
Plush & highly adjustable suspension
Maestro linkage offers terrific efficiency
Great geometry for high-speed brawling
Flip chip is useful & offers mullet compatibility
Fantastic tyre spec
Internal storage hatch is too small
Rear hub pickup speed
35mm bars are very stiff
May 2022 · Alex Evans
At full chat, it’s exhilarating to ride, but back from the limit it feels stiff and the 25kg weight, plus long chassis, makes it tricky to tame
Accurate and stable at speed
Powerful Yamaha motor
Well-specced
Harsh ride that can be punishing
Motor efficiency not great
Weight and geometry work against lighter riders

There are bikes that make it easy to ride fast. They offer a lot of grip, the rider is positioned centrally on the bike and they're easy to handle. The GIANT Reign is NOT that kind of bike. Still, it's a lot of fun!
Good poppy suspension
A lot of fun with an active riding style
Its length adds stability in steep terrain
Suspension reaches its limit on rough tracks
Requires an active riding style
Sizing excludes a lot of riders
