Giant Defy Advanced E+ Elite 2 25km/H eRoad Bike in Mercury

Season:2026

Brand:Giant

Code:6400002Mercury

With its smooth-riding composite frame, lightweight battery, and new SyncDrive Move Plus integrated rear hub motor, the Defy Advanced E+ 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.

Features:

  • SEAMLESS POWER
    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.
  • SYSTEM INTEGRATION
    The down tube integrated EnergyPak 400 battery system weighs just 2.3kg and is purpose-built for the specific needs of E-bikes. A top tube mounted RideControl Go button makes it quick and easy to turn the E-bike on or off and change power modes. Smart Assist technology uses three sensors to precisely measure the power being applied to the pedals and produce just the right amount of support for a smooth, natural ride experience. All models feature SRAM wireless electronic shifters and an integrated taillight.
  • PURE ROAD PERFORMANCE
    A lightweight composite frameset and high-performance components including a D-Fuse seatpost and handlebars for compliance, integrated WheelSystems with tubeless tires, and a wireless electronic drivetrain all add up to a smooth, efficient ride quality that mirrors the award-winning performance of the Defy endurance road bike range.

  • Weight
    The most accurate way to determine any bike’s weight is to have your local dealer weigh it for you. Many brands strive to list the lowest possible weight, but in reality weight can vary based on size, finish, hardware and accessories. All our bikes are designed for best-in-class weight and ride quality.
