The Giant Defy Advanced E+ Elite 0 in Blue Dragonfly is the "superbike" of the Giant endurance e-road lineup. This model is essentially the electric equivalent of a WorldTour-level endurance machine, dripping with top-tier components like SRAM Red AXS and Cadex tires.
The Blue Dragonfly finish is a deep, iridescent teal-blue that shifts under the light, giving the bike a premium, high-velocity look. Weighing only about 11.8kg–12kg (size dependent), it is significantly lighter than most e-bikes on the market, offering a ride feel that is incredibly close to the non-electric Defy.

Key Highlights
The Flagship Spec: This is the only model in the range to feature the SRAM Red AXS groupset and Full Carbon SLR Cockpit, making it the lightest and most responsive build available.
Bonus Button Integration: Because it uses SRAM Red, you can program the buttons on the top of the shifter hoods to control your motor modes. This allows for a completely clean handlebar setup with no extra wires or buttons needed.
SyncDrive Move Plus: The hub motor is specifically tuned for road cadences. It doesn't lunge from a stop; instead, it matches your pedalling input with a smooth, linear power curve that feels like "super legs."
D-Fuse SLR System: The combination of the SLR-grade carbon handlebars and seatpost provides significant vibration damping, making it one of the most comfortable bikes for century rides and rough tarmac.
