A startup bike-sharing outfit from China is heading toward a collision with San Francisco officials over its plan to deposit hundreds, maybe thousands, of its GPS-equipped, smartphone-enabled bikes on city streets — without seeking city permits or approval or letting anyone in on its plans. The impending arrival of Bluegogo, a company that says it intends to disrupt the bike-sharing industry, has enraged city officials as well as the existing Bay Area Bike Share operation, transportation planners and bicycling advocates. In a letter to the CEO of Bluegogo’s Bay Area operations, based in Santa Clara, late Monday, the heads of the Municipal Transportation Agency and Public Works Department demanded the company explain itself and get the necessary permits to operate in the city. Wednesday morning, Supervisor Aaron Peskin planned to hold a news conference on the steps of City Hall to denounce Bluegogo’s plans and to introduce legislation that will increase fines for unauthorized use of city sidewalks and streets.
