Reign E+ 1

$6,700

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.

Key Performance Factors

Trail technology

Proven Maestro rear suspension (160mm) and a powerful but compact SyncDrive Pro motor boost your capabilities on steep climbs and rugged descents. Progressive geometry with a shorter rear end and longer reach allow superior handling and agility on technical terrain.

Total control

RideControl Ergo 3 offers integrated, user-friendly button controls that are easy to use. The Giant E-bike App gives you tuning options and E-bike specific fitness tracking.

Long-lasting power

Climb steep mountains and enjoy ripping descents all day long with the new downtube-integrated EnergyPak battery system featuring 800Wh of capacity.

Range

How far can I expect to ride on a single battery charge?

The range for a single battery charge can vary greatly depending on conditions such as the combined weight of the rider and cargo; wind resistance; tire pressure and tread profile; terrain and elevation changes; road or trail surface; outdoor temperature; maintenance of the E-Bike; and the condition of the battery.

The bar below gives an approximate range. Conditions are categorized as extreme, good and ideal. Extreme conditions typically occur when riding with a heavy load, strong headwinds or excessive climbs.

  • Weight
    The most accurate way to determine any bike’s weight is to have your local dealer weigh it for you. Many brands strive to list the lowest possible weight, but in reality weight can vary based on size, finish, hardware and accessories. All our bikes are designed for best-in-class weight and ride quality.
