Total control: RideControl Ergo 3 offers integrated, user-friendly button controls that are easy to use. The Giant E-bike App gives you tuning options and E-bike specific fitness tracking.

Long-lasting power: Climb steep mountains and enjoy fun descents all day long with the new downtube-integrated EnergyPak featuring 800Wh of capacity.


  • Aluxx SL Aluminium Technology: This High-Performance level, state-of-the-art aluminium material is made predominantly from 6011 alloy and delivers best-in-class strength-to-weight ratios. These framesets also feature unique welding technologies for high-performance ride quality.
  • Hybrid Cycling Technology: Hybrid Cycling Technology is a system that combines electric power with human power to produce a smart, natural and powerful E-bike riding experience. It's an integrated group of technologies that includes our RideControl control unit, EnergyPak battery systems and SyncDrive motor. For more information, check out the link below.
  • Maestro Suspension Technology: Four strategically positioned pivot points and two linkages all work together to create a single floating pivot for the most active, efficient and independent suspension system on the trail.
  • 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.
  • Sync Drive Pro: 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.
  • 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.
  • Energy Pak Plus: This range extender can boost total capacity by 250Wh. It has all the latest technologies combined with an up-to-date design that fits a select number of bikes. It has smart technology so it automatically turns on when your battery loses power, giving you peace of mind that you can reach your destination.
  • Energypak: 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.
  • Ride Control Go: Available on premium Giant E-Bikes, RideControl Go features a multipurpose button integrated into the top tube. Colored LEDs allow you to switch power modes from the top tube and keep a clean handlebar setup. The lights also display battery level and support mode.
  • Ride Control Ergo 3: This updated control system features clean buttons that are integrated with the handlebar grips. You can install the three-button control on the left or right side, making it easy to switch power modes. You also have the option of adding a second control on the other side. Using the RideControl App, you can configure it to your own personal preferences.
  • Flip Chip Maestro: The flip chip allows riders to quickly adjust the geometry of their Maestro-equipped mountain bike to better suit how and where they ride. It lets riders change the headtube/seattube angles and bottom bracket height via eccentric (offset, two-position) hardware located on the upper rocker arm.
