GLEN ROCK, NJ - Police have noted multiple reports of bicycle flash mobs, one most recently on Sunday, when a group of 25 to 30 juveniles were riding their bikes "in a reckless manner along Lincoln Avenue."

Around 4 p.m. on July 26, the kids were riding on "both the street and the sidewalks intentionally blocking traffic and creating dangerous conditions for vehicles and pedestrians, as well as themselves," police said.

A Special Officer on patrol in the area was able to locate the group on Doremus Avenue, police said, however, the cyclists refused to yield for the Special Officer who requested a supervisor to respond.

As a Patrol Sergeant and regular Police Officer arrived, the group continued on Doremus to Ackerman Avenue and then onto Broad Street into Ridgewood as they continued to ignore officers’ instructions to move to the side of the roadway, police said. 

The matter was turned over to the Ridgewood Police Department as they entered their jurisdiction. 

The Glen Rock Police Department has received a few similar reports which is often organized via social media and creates dangerous situations with cyclist refusing to stop for moving vehicles or yield to pedestrians, police said. 

"With an increase of bicyclists and pedestrians, it is paramount that we maintain an environment where everyone can safely use the roadways," Chief Dean Ackermann said via his weekly police blotter. "When cyclists choose to ride along any public roadway, they are subject to the rules of the road and traffic laws. Parents should caution their children about the dangers and potential liability of participating in these bicycle “flash mobs”."
