Where can i take my friend to ride a dirtbike in phoenix, arizona? - dirtbike birthday cake

He loves to watch motocross, but never traveled to so I think it would be nice to have somewhere for her birthday to rent some equipment and a bicycle, and perhaps learn some lessons. I know nothing about motorcycles or someone who does. She was only 16 years old and do not have much experience driving anything and live in the Valley of eastern Arizona, so if you know what is in that general area or anywhere in the valley, which lead to what would be nice could.
