The NYPD announced today that it is offering $100 for every illegal dirt bike or all-terrain vehicles confiscated and ask anyone with information about where bikes are being kept to call Crime Stoppers.

They say the dangerous and illegal bikes will not be tolerated in the city.

The revving engines of dirt bikes and ATVs have become a familiar sound across the city and in the Bronx, but besides being an annoyance, the NYPD says they are dangerous.

Police say they are refocusing their enforcement on illegal bikes. They say they will not only seize, but will also destroy those that don't have a rightful owner in a crushing machine.

"Parked vehicles on our public streets will be towed and impounded," warns NYPD Chief of Transportation Kim Royster.

Besides asking for the community's help, they say they're using social media and body camera video to help track down bikes and confiscate them after they've been speeding the streets.

"Our officers will not engage in pursuits when the danger of the pursuit outweighs the violation," Royster says.

Police say motorcycle-related injuries are up across the city.

"Confiscating these bikes will increase pedestrian safety, improve traffic conditions and diminish noise," says NYPD Chief of Department Rodney Harrison.

The NYPD also says it wants people to know e-bikes are legal and asks that parents do not buy illegal street bikes for their kids. The NYPD says it will continue to work on educating the community on the dangers of dirt bikes and ATVs.
