Reign Advanced E+

These user-friendly components and technologies—including motors, control units, battery packs and more—function as part of the overarching system that seamlessly combines electric power with human power to produce a smart, natural, powerful and secure ride experience.

Mainframe and rear swingarm crafted with high-performance grade raw carbon fiber and custom resin that’s custom made in Giant’s own composite factory. Handcrafted monocoque construction makes it extremely lightweight, stiff and compliant. 

Four strategically positioned pivot points and two linkages all work together to create a single floating pivot for the most active, efficient and independent suspension system on the trail.

Powerful new 48-volt system delivers up to 800 watts of peak power while producing less heat and motor stress—improving efficiency to give you more peak power for longer. You can tune and adjust torque and support levels to match your ride. Choose full power for steep climbs, or dial it back to save energy on long rides.

Six smart sensors precisely measure your power input, speed and cadence, as well as the slope of the terrain you’re riding on, to provide just the right amount of support for a natural, powerful riding experience.

Integrated 560Wh battery pack powers a 48-volt system that produces more power with less heat and stress on the battery cells. Exceptionally durable, it delivers up to 2300 full charge cycles—more than any other E-bike battery—and recharges rapidly, reaching 80% battery capacity in as little as two hours.

New 3-button remote blends seamlessly with your handlebar and grips and has a larger, more concave shape with improved tactile feedback. It can be mounted on the left or right side—or put one on each side for dual remote setup.

Multifunctional button integrated into the top tube makes it quick and easy to power the E-bike and lights on and off. The button is paired with large full-color screen to view battery status, remaining range, and front and rear tire pressure—along with key ride data including speed, time, distance, and cadence.

Quickly adjust the frame geometry to three different positions (low, mid, high) to suit your riding style and terrain. The adjustment affects the head tube and seat tube angles. It’s easy to do using eccentric hardware (flip chips) located on the upper rocker arm of the Maestro rear suspension system.

A three-position flip chip at the headset lets you adjust cockpit dimensions and geometry to dial in your reach for a precision fit and optimal handling to match your riding style and terrain. You can choose from three different positions (short, mid, long) at 5mm increments using chips that are easily removed and swapped.

The E-Lock disables motor support and digitally locks the bike via app, remote, or PIN. If moved without authorization, an audible alarm sounds instantly, ensuring peace of mind and real protection every time you stop.

Enhanced security and anti-theft feature using Apple Find My function lets you set up separation alerts, locate your E-bike remotely and receive notifications if its location changes. Privacy protections ensure that your location information is encrypted on Apple servers and retained for only 24 hours.
