WEST ALLIS, Wis. (CBS 58) -- Whether on the street, the sidewalks, or even the highways, it seems like scooters are everywhere this summer. They are a growing part of transportation but also causing some problems.

On Tuesday night, West Allis police were led on a chase by masked teens on scooters.

“Alright, scooter pursuit," West Allis police are heard saying on scanner audio. “Openly carrying a firearm on his right hip.”

West Allis police say they responded to a call near S. 100th St. and Schlinger Avenue where a man reported two boys on Lime scooters were shooting fireworks at him. Police say one of the fireworks almost hit the man in the face before exploding inside his car. Both teens were arrested shortly after.

“You had that call where the juveniles on the scooters were throwing fireworks at him. One of the guys we took into custody had fireworks on him," West Allis police said on scanner audio. “We’re taking them both into custody, we got them both.”

This is just one of many scooter-related incidents that have happened this month.

“We’re starting to hear from other communities; we’re starting to hear from the suburbs that have similar concerns," said Milwaukee Alderman Bob Bauman.

The Department of Transportation cameras picked up video of a person riding a Lime scooter on the Hoan Bridge.

Last week, a Milwaukee man was charged with a felony after allegedly hitting a pedestrian with a Lime scooter on the east side. The victim was severely injured and had to have a spinal fusion.

“I think at some point, we have to ask the question -- is the utility of these scooters worth the public safety danger?" said Bauman.

That’s why Ald. Bauman is proposing the speed on these scooters be brought down five miles an hour in downtown Milwaukee.

The city is also considering increasing fines by up to $200 for those riding scooters on the sidewalks. Currently, those riding scooters on sidewalks are fined anywhere from $10-$20.

Those proposals will go in front of the public safety committee next week.

“If we can’t stop sidewalk running, at least we can reduce the damage riders can do to pedestrians," said Bauman.
