SyncDrive Pro has Smart Assist technology and is tuned to deliver a powerful, high-performance ride with improved assistance at higher cadences. Our most advanced motor system has 80Nm of power output and offers superior torque and support ratios up to 360 percent. This means that, in the Power mode, 100 percent of human torque input offers 360 percent pedal-assist. With the new and adjustable support ratios, the rider can decide what ratio they want the motor to provide. This offers more freedom in the way the motor reacts to rider input and how the E-bike rides and handles.
