Electric scooters have become the hot new area for startups and “innovation.” For those who haven’t been keeping track, there are three main players in the Silicon Valley scooter wars: Bird, Lime and Spin. Bird first launched in Venice, Calif. before expanding into San Francisco in March. It’s worth pointing out that Bird, for now, is strictly an electric scooter company. That’s not the case for Lime and Spin, which both have their own bike-share services deployed throughout various parts of the country and world.

That same month — almost in complete lockstep — Lime and Spin deployed their own electric scooters in the city. Fast forward to June and the city of SF has placed a temporary hold on electric scooters until it can review permit applications. As part of a new city law, which went into effect June 4, scooter companies are not able to operate their services in SF without a permit.
