Giant’s new PedalPlus 6-sensor technology is used in SyncDrive Life motor technology and features an additional slope detection sensor and accelerometer. While the PedalPlus 6-sensor technology can detect slopes, it also offers an automatic smart support mode function, which helps riders experience a more effortless ride experience. This new sensor technology calculates the amount of torque, cadence, slope and speed and, based on these calculations, determines the amount of motor output the rider needs.
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 traveling
MOTOR AND PEDAL ROTATION SENSORS
Allows the motor to run as smoothly and seamlessly as possible.
SLOPE DETECTION SENSOR TECHNOLOGY
Calculates the steepness of a slope the bike is on, and the amount of acceleration or deceleration the rider puts in. Based on the slope measurement, combined with the other factors, the system is able to automatically adjust motor output.
ACCELEROMETER
Measures the amount of acceleration or deceleration the rider puts in. Based on the amount of acceleration, combined with the other factors, the system is able to automatically adjust motor output.
Innovation, manufacturing expertise and a motor system powered by Yamaha all combine to expand any rider’s abilities.
