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.

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. For more information, check out the link below.

RideControl ONE

RideControl ONE takes your E-bike riding experience to new levels with integrated button controls and a clean handlebar free of any display. The E-bikes equipped with RideControl ONE can connect with the Giant E-bike App to function as your E-bike display

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.

Tubeless System

Fewer flat tires. Greater traction. Less rolling resistance and a smoother, faster ride. Giant’s Tubeless System makes it easier than ever to experience all these benefits.

SyncDrive Sport

Innovation, manufacturing expertise and a motor system powered by Yamaha all combine to expand any rider’s abilities. SyncDrive Sport offers three support modes and is equipped on E-bikes that are used for both everyday riding and for more demanding off-road riding. This small mid-drive motor delivers a massive maximum 70Nm of torque and is widely acclaimed for its performance and reliability.

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.
