Scooters belonging to two companies, available for public use through mobile apps, were seized by Denver officials this week off downtown sidewalks and impounded at city maintenance facilities.

The city “removed 264 scooters from the public right of way” as of Tuesday afternoon, said Nancy Kuhn of Denver Public Works.

The city gave the scooter companies, Lime and Bird, “instructions” on how to retrieve the scooters. The city this week has also given the companies $150 fines per scooter seized.

“That cost could escalate to $500 and $999 per scooter if we pick up the same scooter multiple times,” Kuhn said in a email.

Last week, the companies had not complied with Denver’s directive to remove the dockless electric scooters from public streets and sidewalks, four days after the city addressed the issue.

Lime and Bird said earlier that they were looking forward to working with the city’s Department of Public Works on rules that could legalize the zippy transports.
