The new EnergyPak is even more integrated with the framesets on Giant E-bikes. The lithium-ion core remains the same and still offers the highest energy density of any E-bike battery in its category.
New features include more streamlined integration with the downtube and top tube to provide a cleaner, more modern profile. And a new side-release design* (not on all models) allows for new frame geometries that are optimized for specific performance factors.
The EnergyPaks are integrated into the frame. This helps stabilize and balance the E-bike while it’s being ridden. You can either (side*) remove the EnergyPak to charge it, or plug the charger directly into the E-bike itself.
