The compact SyncDrive Sport motor has Smart Assist technology and is sonically tuned for smooth, quiet performance. It’s an ideal choice for riders seeking a versatile, do-it-all E-bike experience. SyncDrive Sport delivers high power, even at low speeds. The Smart Assist technology calculates the amount of torque, cadence, slope and speed and, based on these calculations, determines the amount of motor output the rider needs. It feels more powerful due to its ability to support higher cadences and faster ramp-up in torque.
