You need to be at least 14 years of age.

i am sure you can be any age
You can be any age to buy a mini dirt bike in the UK wether your 6 or 16 you can buy one but you are not allowed to ride one on the road at any age in the UK you would have to take the mini dirt bike to a dirt track and you can book weekly sessions with them so you can go like 3 times a week if you wanted to. So you are allowed to buy a mini dfirt bike at any age you just can't ride it on the road. i hope that's a help.
Different states have different laws when it comes to dirt bikes. In California, you can ride a dirt bike at any age as long as it is not on the road.
I recently purchased a mini bike and the manual says no one under the age of 16 should ride alone
you can ride a dirt bike at any age
There is none you need to get a lisense at at least 16 then you can
Yes I was 10 when I was allowed to ride a mini moto/cycle but I had to wear protective gear
80
18 years or older
Miley Cyrus probably learned to ride a bike when she was around 6 years old. She has never mentioned in interviews that age she learned to ride the bike.
