Park-‘em-anywhere electric scooters — i.e., adult versions of the Razor with a dockless twist — are now available on the sidewalks of San Francisco and San Jose, as well as Los Angeles and Washington D.C.

Santa Monica, California-based dockless scooter start-up Bird began offering their black-and-white two-wheelers in the Bay Area cities last weekend, the San Francisco chronicle reports. Waybots, another California start-up, rolled their scooters out in D.C. in February. And Limebike, a dockless bike-share operator, is also testing electric scooters in San Francisco.

To coincide with its Bay Area expansion, Bird released a pledge entitled “S.O.S.,” or “Save our Sidewalks,” addressed to the CEOs of four dockless bike-share start-ups, LimeBike, Ofo, Mobike and Jump.
