The 2021 GIANT Reign Advanced Pro 0 review – Let's get rowdy!

Jan 2021 · Christoph Bayer

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!

Highs
  • Good poppy suspension

  • A lot of fun with an active riding style

  • Its length adds stability in steep terrain

Lows
  • Suspension reaches its limit on rough tracks

  • Requires an active riding style

  • Sizing excludes a lot of riders

Giant Reign E+ 0 Pro in Review

Dec 2019 · Felix Stix, Robin Schmitt, Jonas Müssig

Carbon, light-weight, large battery: all these are foreign terms to the Giant Reign E+ 0 Pro. Can its robust features and componentry convince nonetheless?

Highs
  • One of the highest weight ratings in the group test

  • Smart Automatic support mode

  • Excellent suspension offering a lot of traction

Lows
  • Energy-robbing on the descents

  • Too little dropper travel/long seat tube

  • Counterintuitive remote sequence
