Every trail, every steep climb, every thrilling descent—nothing is out of bounds with the Reign E+. Tested and developed by Giant’s e-bike enduro pros, this proven trail ripper gives you the power to enjoy the best parts of the ride again and again. With its proven Maestro rear suspension (160mm) and a powerful yet compact SyncDrive Pro motor, you gain enhanced capabilities on steep climbs and rugged descents. Its progressive geometry, featuring a shorter rear end and longer reach, ensures superior handling and agility on technical terrain. The RideControl Ergo 3 provides integrated, user-friendly button controls, and the Giant E-bike App offers tuning options and e-bike specific fitness tracking for total control.
KEY PERFORMANCE FACTOR
Lighter Weight
New EnergyPak 400 battery is designed to be ultra slim. You get all the power but in a smaller package that’s cleanly integrated with the composite frameset.
Advanced cockpit control
RideControl Ergo 3 remote attaches to the all-new composite Giant Contact SLR integrated handlebar. The control can be mounted to either side of the handlebar so you can customize your controls for a clean, uncluttered cockpit.
More Power
New SyncDrive Pro motor, co-developed with Yamaha, puts out a powerful 85Nm of torque and weighs just 2.7kg. The result is quicker acceleration and climbing capabilities on technical trails.
