D.C. allows dockless bikes and scooters to stay, but you’ll have to start locking them up.

The District Department of Transportation is extending through December the pilot program that allows the operation of dockless bikes and electric scooters. But moving forward, the companies that operate the services will be required to provide a method for users to lock the bikes to racks or poles.

The city plans to take the next few months to transition to a more permanent program. DDOT is slated to unveil new regulations next month that will establish operation fees and reassess the existing cap on fleets. The department will also more clearly define rules for bike and scooter parking. The policies will aim to balance the city’s desire for mobility innovation, sustainability goals and public safety.
