City supervisors are scoffing at an allegation by Bird, one of three companies that has dropped shared electric scooters on the streets and sidewalks of San Francisco, that San Francisco supervisors were set to ban the motorized devices within days.

Supervisor Aaron Peskin, who’s been leading the charge for regulation of the rental scooters, said the allegation was, well, bird-brained.

“Those people are out of their minds,” Peskin said late Wednesday from Southern California, where he was attending a state Coastal Commission meeting. “It’s amazing that a company with that kind of money would spread such misinformation. It’s made out of whole cloth.”

Bird, in a “breaking news” missive emailed to The Chronicle and at least one other news outlet Wednesday night, said the Board of Supervisors was plotting “an unusual action” on Monday known as an emergency ordinance.

That’s when the board’s Land Use and Transportation Committee is scheduled to take up a Peskin proposal to allow the Municipal Transportation Agency the authority to regulate shared motorized scooters. It’s a fairly bureaucratic action that would let the MTA create a permitting process and remove scooters without proper permits from the streets and sidewalks.

But that’s not how the folks at Bird saw it from their perch in Venice Beach.

“It has come to our attention that the San Francisco Board of Supervisors is considering banning Birds and other electric vehicles — and doing so via an extraordinary regulatory maneuver, usually reserved for emergencies like earthquakes,” Bird’s statement read.

Ken Baer, a spokesman for Bird, said Thursday that the company’s representatives in San Francisco had heard that an urgent move was afoot to ban the shared scooters, and felt the need to launch a counterattack.

As evidence, he cited a quote from Supervisor Jane Kim on Walk San Francisco’s Facebook page: “We should remove these scooters immediately until we implement common-sense rules to keep people safe.”

Ivy Lee, Kim’s chief of staff, said Thursday that the supervisor has no intention of banning scooters and was aware of no such plans.

“As far as we know, there is zero in the works,” Lee said.

Lee said Kim sees the scooters as a way of getting more people out of their cars, but she wants to keep them off sidewalks.

“Sidewalks should be for people who are walking,” Lee said.

Bird, along with the firms Lime and Spin, suddenly deposited hundreds of electric-powered standup scooters on San Francisco sidewalks about two weeks ago. The scooters can be dropped off anywhere, which has led to a flood of complaints that they’re left blocking sidewalks and building entrances. Critics also say riders use the scooters on sidewalks, which is illegal.

But the scooters are clearly popular, especially downtown, South of Market and in the Financial District, where riders take them from BART to work, meetings or lunch. Bird stressed that point in its release.

“Rushing through a moratorium on Birds and similar vehicles, without the input of San Franciscans and without careful deliberation, ignores the fact that thousands of city residents love using Birds to get around a growing — and congested — city, and feel good doing so because it does not add to traffic or carbon emissions.”

The company ended its message with a cry — a caw? — for support from riders.

“Listening to the people is not only fundamental to democracy,” Bird wrote, “but it is also how San Francisco works — and works best.”
