Technologies

Aluxx SL Aluminum Technology

This High-Performance level, state-of-the-art aluminum material is made predominantly from 6011 alloy and delivers best-in-class strength-to-weight ratios. These framesets also feature unique welding technologies for a high-performance ride quality.

Hybrid Cycling Technology

Hybrid Cycling Technology is a system that 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 systems and SyncDrive motor.

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.

Syncdrive Pro

SyncDrive Pro powered by Yamaha is designed for high-performance E-bike riding. Giant tuned the motor to make it more powerful, producing a performance-oriented riding style. The lightweight, compact SyncDrive Pro motor is used primarily on Giant's high-performance models.

Smart Assist

All SyncDrive motors have Smart Assist technology, which adjusts the support to match the rider's needs. By using information from multiple sensors, both rider input and terrain feedback are used to determine the optimal amount of pedaling assistance. SyncDrive is the only e-bike system that utilizes both rider input and terrain feedback. It gives you a smooth, natural riding experience with ample power when you need it, while also conserving power when you don't need as much.

Energypak

Giant's latest EnergyPak battery systems feature streamlined designs that are integrated with the E-bike for a sleek and modern profile. Giant E-bikes offer several different EnergyPak options including the EnergyPak Smart and EnergyPak. Each one is designed to optimize the E-bike experience for a specific style of riding.

Ridecontrol Ergo 3

This updated control system features clean buttons that are integrated with the handlebar grips. You can install the three-button control on the left or right side, making it easy to switch power modes. You also have the option of adding a second control on the other side. Using the RideControl App, you can configure it to your own personal preferences.

Ridecontrol Go:

Available on premium Giant E-Bikes, RideControl Go features a multipurpose button integrated into the top tube. Colored LEDs allow you to switch power modes from the top tube and keep a clean handlebar setup. The lights also display battery level and support mode.
