Police have warned children not to ride miniature motorbikes in public places because it's dangerous and illegal.
It's against the law for people to use them anywhere other than on private land such as specially built tracks.
The small bikes can reach speeds of up to 50mph, can be very noisy and are often ridden without safety helmets.
Six UK councils have now agreed to open up their empty car parks to give mini motorbike users a supervised, safe and legal space to ride their bikes in.
Mini motorbikes look like real racing bikes but because of their petite size and small engines they are much cheaper.
This means it's easier for kids to get their hands on them.
Avon and Somerset Constabulary's Superintendent Lawrie Lewis warned people to think carefully about where they plan to ride their bike.
He said: "Parents have been buying them for youngsters and they're out on the streets.
"They are dangerous, noisy and cause a nuisance and we are concerned about the safety angle."
