How old do you have to be to ride a dirt bike on the street in Las Vegas?
You can NOT ride a dirt bike on any street in Las Vegas or in the county. You have to be 1000 feet from any street or building to ride one in the dirt.
The ride will be rough because of the knobby tires, but you can ride a dirt bike on pavement. If you intend to ride a dirt bike on a city street or a highway (which I do not advise), be sure it can match the speed of the vehicles around it. Also, wear protective gear. Other motorized vehicles aren't very forgiving if you run into them or if they run into you. ;)
