Up to (3) water bottle accessory and top tube gear bag mounts.

- Powerful support
Featuring our most powerful off-road motor & EnergyPak. The SyncDrive Pro motor, delivers up to 85Nm of smooth, natural pedaling power and up to 400% rider support ratio. Fueled by EnergyPak 800 providing 800Wh of power for longer rides & high output lighting. Optional range extender Energy Pak 250 & 200 also available for more epic adventures.


This High-Performance level, state-of-the-art aluminum material is made predominantly from 6011 alloy and delivers best-in-class strength-to-weight ratios. These framesets also feature unique welding technologies for a high-performance ride quality.

Giant’s original oversized fork steerer tube technology. Designed to provide precise front-end steering performance, the system’s oversized headset bearings (1 1/4” lower and 1 1/8” upper for road, 1 1/2” lower and 1 1/8” upper for mountain) and tapered steerer tube work in conjunction to provide optimal steering stiffness.

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.

SyncDrive Pro powered by Yamaha is designed for high-performance E-bike riding. Giant tuned the motor to make it more powerful, producing a performance-oriented riding style. The lightweight, compact SyncDrive Pro motor is used primarily on Giant’s high-performance models.

This new control unit is optimized for city and trekking bikes that don’t have front derailleur or dropper seatpost levers on the handlebar. It’s optimized for ergonomics, with larger buttons that are easy to reach. LEDs indicating battery level and support mode make it a standalone control unit that doesn’t require a display. A smaller 6mm connector makes it possible to have internal handlebar cable routing.

The RideDash EVO is completely revised for 2021. It has a sportier outlook with a full-color display and graphics showing new functionalities to enhance the E-bike riding experience. It has handlebar/stem integration options and a reliable, wired connection. The low-profile screen shows ride information including speed, distance, battery range and Navigation, heart rate and fitness require the app to be connected.
