Lake Illawarra's community safety officer Sergeant Peter Northey said the arrests were a timely reminder to anyone in possession of a trail bike to adhere to road rules.

"For those who own a trail bike, please get to know the road rules," he said.

"Remember it is illegal to ride an unregistered trail bike on NSW roads.

"It is not only unlawful, it is a big distraction to drivers and other road users, not to mention not very safe.

"It is extremely dangerous for the riders and other road users."

Sgt Northey said members of the community were "fed up" and "had enough" of illegal trail bike riders, and the unit would be out in force to catch them.

"People don't want the unregistered riders out on the road," Sgt Northey said.

"They are a big disturbance to the community.

"We do regularly get calls to the station and via Crime Stoppers of reported trail bike riding.

"We encourage residents to keep reporting it.

"Let us know where the riders are, where they have come from and where they go to.

"We take every call seriously and we will investigate the reports, and hopefully put a stop to it."
