Key Performance Factors
Power up climbs
The SyncDrive Pro motor is engineered for performance riding. With a max 80Nm of torque and our Smart Assist mode, it helps you conquer climbs with ease.
Longer distance
The new integrated EnergyPak Smart Compact 500 battery delivers 500Wh of power and is built with the highest energy density possible. So you can ride longer and cover greater distances. (Road-E+ 1 Pro model only, the Road E+ 2 Pro battery delivers 375Wh).
Smooth control
Giant Tubeless Ready wheels and tyres offer lower rolling resistance, a smoother ride quality, and improved puncture protection.
Range
How far can I expect to ride on a single battery charge?
The range for a single battery charge can vary greatly depending on conditions such as the combined weight of the rider and cargo; wind resistance; tyre pressure and tread profile; terrain and elevation changes; road or trail surface; outdoor temperature; maintenance of the E-Bike; and the condition of the battery.
The bar below gives an approximate range. Conditions are categorized as extreme, good and ideal. Extreme conditions typically occur when riding with a heavy load, strong headwinds or excessive climbs.

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.
D-Fuse Technology
The D-Fuse seatpost and handlebar were designed to function as a system, absorbing road shocks and vibrations so you can ride farther, faster.
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.
RideControl Ergo 2
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.
RideDash Evo
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.
SyncDrive
Revolutionize your ride with an E-bike motor system that adapts to you. Experience natural momentum in motion as SyncDrive technology enhances every moment of your journey, opening new horizons for every rider.
