Technologies

Aluxx SL Aluminium Technology: This High-Performance level, state-of-the-art aluminium material is made predominantly from 6011 alloy and delivers best-in-class strength-to-weight ratios. These framesets also feature unique welding technologies for high-performance ride quality.
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 optimise the E-bike experience for a specific style of riding.
Energy Pak Plus: This range extender can boost total capacity by 250Wh. It has all the latest technologies combined with an up-to-date design that fits a select number of bikes. It has smart technology so it automatically turns on when your battery loses power, giving you peace of mind that you can reach your destination.
Ride Control Dash: This two-in-one unit features buttons to control support modes plus an integrated colour display. You can check range, battery level and support mode, along with standard cycling data such as speed and distance without having to another screen to the E-bike. It also has an ANT+ connection so you can connect a heart rate monitor and other fitness devices.
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 pedalling assistance. SyncDrive is the only E-Bike system that utilises 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.
Sync Drive Pro 3 X: Delivers up to 800 watts of peak power and 100Nm of torque for fast response, balancing high output with precise control for confident, capable trail riding. Engineered to maintain powerful assist levels even at high cadences, giving you sustained support over longer periods.
