PedalPlus 4: Giant’s PedalPlus 4-sensor technology precisely measures the amount of force a rider is applying to the pedals so that the motor delivers a seamless power boost. The system uses speed and torque sensors along with motor and pedal rotation sensors to produce even power across the entire gear range. The result is predictable power that feels totally natural in any gear and makes riding the bike feel smooth and powerful on all types of terrain.
TORQUE SENSOR TECHNOLOGY The torque sensor reacts to pedal pressure. The more pressure you apply to the pedals, the more support you get from the motor. It precisely measures this force so that the motor can deliver a seamless power boost.
Speed Sensor Technology The speed sensor works independently from the pressure you are putting on the pedals. It precisely measures the speed the rider is travelling.
MOTOR AND PEDAL ROTATION SENSORS Allows the motor to run as smoothly and seamlessly as possible
NATURAL FEELING: The torque sensor measures the amount of power the rider is applying to the pedals so that the motor can replicate the natural riding style, adding assistance when needed.
EFFICIENCY: The PedalPlus 4-sensor technology maximises energy efficiency for both the rider and the battery system.
Instant Support: The combination of the sensor technology and the instantaneous response of the SyncDrive motor creates a smooth and powerful riding experience.
Side Release EnergyPak: The side release EnergyPak can be removed from the frame by moving it sideways. This allows for more compact frame designs and lower stand-over heights. The side release batteries have a capacity of 400Wh and 500Wh and are used on mountain and trekking E-bikes. The total weight of these EnergyPaks is 3.2kg, optimising the balance and performance of the E-bike.
LOWER STAND-OVER HEIGHTS: Lower stand-over heights make it easier to get on and off the E-bike.
Optimised GEOMETRIES: More compact frame designs are now possible with the new side release EnergyPak.
EASY HANDLING: The side removable EnergyPaks are easy to handle and remove from the E-bike.
