<HTML> In California a moped is defined as having pedals and less than 2 horsepower. You must have a minimum of a car drivers license and insurance. The good thing about the law here is that a moped doesn't need annual registration.
Your Sundiro would be classified as a motor-driven cycle which requires a motor-driven cycle endorsement on your license, hence a driving test. Registration is annual and also requires insurance. Motor-driven cycles are not allowed on freeways.
That's it in a nutshell....
