The Reign was both the easiest and the hardest bike I’ve tested so far. The easiest because it was exactly what I expected and hoped it would be: an aggressive enduro bike with excellent suspension performance. The hardest because, well, I’m just not that aggressive of a rider so I had to step out of my comfort zone and I had to be at the top of my game to get the most out of the bike.

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

Entry-level 650b enduro and bike-park rig
Price is very competitive for this level of finish and components
Lightweight for its price and travel
Fork lacks smoothness
No dropper post
Doesn’t pedal uphill too well

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
