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.

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

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.

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.
