Pocket bike 49cc Was towed today -Police gave tickets in Arizona?

We Answered:

I doubt Wikipedia will tell you why Arizona is in the business of towing non-vehicles.
Try http://www.azdot.gov/ and http://www.azleg.gov/ , it is too much for me to read.

Edit: Perhaps the reason I did not come across the Arizona law is because this is regulated by local ordinance. For example, Gilbert and Mesa do not require a license or insurance to ride a pocket bike on private property.

The AZ MVD likes to think of the pocket bike, not as a toy but, as an unregisterable *motor driven cycle* which requires a license and insurance. So even if you have a license and insurance on a pocket bike, you will run into the legality of registration.
