Techs & Features

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.

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.

EnergyPak 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.

RideControl App

The updated RideControl App expands the existing customization options for your SyncDrive motor. Now you choose exactly how you want the system to perform. You can use the app to adjust from the battery-saving Eco mode all the way up to Power mode, and collect all relevant ride metrics during your activity.

RideControl Dash

This two-in-one unit features buttons to control support modes plus an integrated color 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 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.
