What does 40 cc mean for a electric motorcycle?

The term "40 cc" is typically used to refer to the engine displacement of a combustion engine Motorcycle, not an electric Motorcycle. Electric motorcycles do not have a combustion engine, so they do not have a specific engine displacement measured in cc (cubic centimeters). Instead, the performance of an electric Motorcycle is determined by factors such as motor power, battery capacity, and other technical specifications. These specifications will vary depending on the make and model of the electric Motorcycle.
