E+ System is a fully integrated electric bike system used across Giant, Liv and Momentum E-bikes. It combines the motor, battery, controls, sensors, components and software into one connected platform, delivering smooth, natural pedal assistance and a seamless riding experience.

The E+ System is designed for all types of riders, from beginners to experienced cyclists. Whether you are commuting, exploring longer distances or riding on varied terrain, the system adapts to your needs. Explore categories like E-MTB, E-Adventure, E-City and E-Road to find the right fit.

Each Giant E-bike is designed as a complete system, with the EnergyPak Battery selected to match the bike’s purpose and performance. Some models offer upgrade options, but the best way to choose is by visiting a Giant dealer who can recommend the right setup for your riding style and needs.

The E+ System includes the motor, battery, controls, display, sensors, software and safety features. At the center of the system is the Smart Gateway, which connects all components and allows them to work together based on your riding conditions.

Each E+ System bike is developed by Giant product managers, designers and engineers to ensure every component works together for the intended riding experience. RideControl interfaces are positioned for intuitive operation, while advanced sensors measure pedaling force, cadence, speed and bike position to adjust assistance in real time. Combined with EnergyPak battery management, high safety standards and long-term reliability, the system delivers support that feels smooth, natural, powerful and tailored to how you ride.

Yes. The system includes Aegis safety technology, which supports features like E-Lock and Apple Find My on compatible bikes. These features help track your bike’s location and improve security when parked.

No, the RideControl App is not required for your E-bike to function. However, it is recommended to unlock advanced features, customize motor settings, track rides and receive system updates for an improved riding experience.

No special maintenance is required beyond regular bicycle care. Keep your E-bike clean, avoid high-pressure water on electrical components and service it regularly. For support and maintenance, visit your local Giant dealer.

E-bike assistance limits depend on local regulations. In most European markets, E-bikes provide assistance up to 25 km/h. In North America, assisted speeds vary by class and typically range from 20 mph to 28 mph. You can ride faster, but motor assistance stops once the legal assist limit is reached.

It is recommended to check and clean your E-bike regularly and have it serviced at least once a year. Frequent riders may benefit from more regular servicing to maintain performance.
