An automatic scooter typically has a continuously variable transmission (CVT) rather than a fixed number of gears. CVT allows for seamless and smooth acceleration without the need for shifting gears manually. Instead of discrete gear ratios, a CVT uses a system of belts, pulleys, and variators to provide an infinite number of gear ratios within a specific range. This design allows the engine to operate at its most efficient speed for a given throttle position, resulting in improved fuel efficiency and ease of use for the rider. So, in short, an automatic scooter does not have a fixed number of gears like a manual transmission vehicle.
