Supervisor Bilal Mahmood is pushing a new proposal to ban the sale of uncertified e-bike batteries in San Francisco, citing the very real fire risks these cheap lithium-ion packs pose — especially in dense apartment buildings where one battery going thermal runaway can endanger dozens of people.

Fair enough. Nobody wants their neighbor's knockoff battery turning into an impromptu incendiary device at 2 a.m. E-bike battery fires are genuinely terrifying: they burn fast, burn hot, and produce toxic fumes that can fill a hallway in seconds. The safety concern here is entirely legitimate.

But here's the thing — California already passed SB 1271, which took effect this year and does... basically the same thing at the state level. So what exactly is the Board of Supervisors adding here?

Mahmood says his legislation would go further by regulating online delivery and giving the fire chief additional enforcement authority. Okay, that's not nothing. But as one SF resident put it, "This sounds like something that should be handled on a state level." And it was. Which raises the eternal San Francisco governance question: is this genuine policymaking or résumé padding?

We're all for public safety measures that actually work. If there are real enforcement gaps in the state law — if uncertified batteries are still flooding into the city through online retailers and nobody's doing anything about it — then by all means, close those gaps. Give the fire chief teeth.

But San Francisco has a chronic habit of layering local regulations on top of state and federal laws, creating a byzantine compliance maze that mostly just generates paperwork and committee meetings. Every hour the Board spends duplicating Sacramento's homework is an hour not spent on the city's actual crises — the ones voters keep saying they care about.

The test for this proposal is simple: does it meaningfully improve on existing state law, or does it just let a supervisor hold a press conference? We'd love to see the specific enforcement mechanisms that justify a local ordinance. Show us the gap, and we'll back the fix. Otherwise, this is government doing what government does best — solving problems that have already been solved.
