Motorcycle License

Hi, I've been trying to find the required age for Saudi Citizens to drive a motorcycle. (to get a license)
the government website says (16 as of 2019), but then when I tell people, they say its 21, BUT THEN ON YOUTUBE, IT SAYS 18, like dude..
so if any of you guys have a motorcycle license that you obtained not too long ago, please inform me what the minimum age is.

How about you go to driving school and inquire?

Theres none near me
