ALUXX SL Aluminum Technology
This state-of-the-art aluminum material is made predominantly from 6011 alloy and delivers best-in-class strength-to-weight ratios. The frameset also features unique welding technologies for a high-performance ride quality.
Hybrid Cycling Technology
This innovative system combines electric power with human power to produce a smart, natural and powerful E-bike riding experience. It’s an integrated group of technologies that includes our RideControl control unit, EnergyPak battery system and SyncDrive Pro motor.
SyncDrive Pro
The new motor is co-developed with Yamaha and optimized for the Reign E+ chassis and Maestro suspension. The compact motor is now lighter (2.7kg) with increased torque output (up to 85Nm) and significantly reduced noise levels.
Ridecontrol Ergo 3
New handlebar remote can be mounted on the left or right side for a clean cockpit layout depending on your preference. You also have the option to add a second control, giving you another three buttons. The buttons can be configured with the RideControl app to fully customize your controls.
Smart Assist
Six smart sensors precisely measure the power being applied to the pedals so the motor can provide just the right amount of assistance to create a natural, powerful riding experience. This helps optimize energy efficiency for both the rider and the battery system.
RideControl App
RideControl Ergo wirelessly connects with the RideControl App so your smart phone can function as a display for ride data and system updates.
EnergyPak Smart
Our most advanced E-bike battery system is cleanly integrated within the downtube of the frame.
RideControl Go
New top-tube integrated, multi-function on/off button can power on the E-bike quickly and easily. It can also change the motor settings.
Maestro Suspension Technology
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.
Giant Tubeless System
Integrated Tubeless Wheel System and tire deliver improved efficiency, comfort and control in the most user-friendly and reliable system.
Adjustable Geometry
A flip chip lets you change the head tube and seat tube angles, along with the bottom bracket height, to fine-tune the handling. You can choose the low setting for faster, more open terrain, or the high setting for slower, tighter singletrack.
