What type of license allows you to ride any motorbike?

The M1 license is the correct answer because it authorizes the holder to operate any type of motorcycle, including standard motorcycles, scooters, and even some types of motorized bicycles and trikes. Obtaining an M1 license typically involves passing a written exam and a riding skills test, demonstrating the necessary knowledge and ability to safely ride any two-wheeled motorcycle.

In contrast, the M2 license is specifically for riding motorcycles with a restricted capacity, often covering only specific types of motorbikes or limited-use vehicles. The other options, such as M3 and M4, do not exist in California motorcycle licensing and would not pertain to motorcycle operation. Thus, to ride any motorbike legally in California, the M1 license is required.
