A Continuously Variable Transmission (CVT) is a type of automatic transmission that provides seamless acceleration without the distinct gear shifts found in traditional transmissions. It uses a system of pulleys and a belt to adjust the gear ratio continuously, allowing the engine to operate at its most efficient RPM for various speeds. CVTs are commonly used in many modern vehicles, including cars and scooters, due to their ability to improve fuel efficiency and provide a smoother driving experience. Unlike conventional transmissions, CVTs can adapt to changing driving conditions, making them popular in both hybrid vehicles and electric vehicles.
