With its smooth-riding composite frame, lightweight battery, new SyncDrive Move Plus integrated rear hub motor and all-road ready 38mm tires, the Defy Advanced E+ AR is the ideal choice for performance-minded road riders who want to tackle steep hills, maintain higher speeds, and experience road riding with no limitations.
The SyncDrive Move Plus motor is integrated into the rear hub and delivers 30Nm of power (equivalent to 75Nm with a mid-drive motor) directly to the rear wheel. Weighing just 1.7kg, it’s specially tuned for the pedaling pattern of performance road riding, with minimal energy loss and more torque at higher speeds. The result is a natural feel when accelerating or maintaining steady power at speed, and no motor drag while freewheeling or coasting.

Key Highlights
The "Secret" Motor: The hub-drive design allows Giant to keep the bottom bracket area slim, maintaining the classic silhouette of the award-winning Defy endurance bike. Most people won't even realize it's electric until you drop them on a 12% climb.
Integrated Lighting: It features a clever integrated tail light built directly into the seatpost clamp, ensuring you're always visible without needing to strap on extra plastic accessories.
D-Fuse Comfort: The "D" shaped seatpost and handlebars are designed to flex under load, absorbing high-frequency road buzz. This makes a massive difference on four-hour rides where fatigue usually sets in from vibration.
Wireless Control: By utilizing SRAM Blips, Giant has moved the motor controls to the handlebars. You can click a button on your hoods to jump from "Eco" to "Sport" mode instantly, keeping your focus entirely on the road.
