What kind of dirt bike should a beginner get? And what kind of gear should I get?

[GummyBearsRule!!!]

It's my first time buying a dirt bike, but i have no clue what brand to get. My friend said to get an automatic and he also said the size of the bike depends on my height. I'm 4ft 11in and i also need a list of the gear I'm gonna need.

Ask in the motorcycle section, this is for bicycles.
