Bird and Lime: The Electric Scooter Sharing Boom (2017-2020)
Lime’s first known deployment launched at the University of North Carolina at Greensboro in June 2017 with shared bicycles. This early bike-sharing base helped Lime move into scooters later, using similar app, payment, and fleet-operations systems. The shift from bikes to scooters would soon become central to the broader “scooter boom.”
In 2017, two startups—Bird (founded in Santa Monica) and Lime (founded in Northern California as LimeBike)—formed around the idea of short, app-based rentals for “last-mile” trips. Their timing mattered: smartphone payments, GPS tracking, and venture capital made it possible to deploy fleets quickly with little fixed infrastructure. This set the stage for fast expansion and conflict with city rules that had not anticipated dockless scooters.
Bird’s early service began with a small initial deployment in Santa Monica, California, and then expanded quickly. The company’s “drop-and-go” approach—placing scooters in public spaces before clear local permitting systems existed—became a template for rapid growth. This also created early tension with city leaders and residents over sidewalk use, parking, and safety.
In March 2018, Lime introduced its Lime-S scooters in San Francisco during a weekend “pop-up” style rollout. This highly visible deployment showed how quickly a company could seed a city with devices and attract riders. It also highlighted a core problem for cities: scooters were arriving faster than enforcement and permitting systems could adapt.
By April 2018, San Francisco escalated its response, with city officials sending cease-and-desist letters to Bird, Lime, and Spin. The city also began confiscating scooters that were blocking sidewalks or otherwise improperly parked. This crackdown became an early landmark in how U.S. cities tried to move from reactive enforcement to formal regulation.
In May 2018, Lime announced it had rebranded from “LimeBike” to “Lime,” emphasizing a broader multimodal strategy. It also publicized a partnership with Segway and plans for updated scooter models in major U.S. markets. The rebrand reflected a turning point: scooters were becoming the headline product for growth and fundraising.
In June 2018, Lime began offering dockless e-scooters in Paris, starting with a limited district rollout and plans to scale. This signaled that the scooter boom was not only a U.S. phenomenon, but also a fast-moving global product category. European deployments soon led to their own debates about public space, rules, and enforcement.
In June 2018, Bird confirmed a $300 million fundraising round led by Sequoia Capital. Large venture rounds like this financed rapid fleet growth, market launches, and operations teams. It also intensified “winner-take-most” competition with Lime and other rivals, increasing pressure to expand faster than city regulation cycles.
In July 2018, Lime announced a $335 million round that included Uber, and said Lime scooters would be accessible through Uber’s app in addition to Lime’s own app. The deal showed how micromobility was being pulled into a wider “platform economy,” where large mobility apps try to offer multiple transport modes. It also raised the stakes for growth, partnerships, and city access.
By August 2018, San Francisco selected two companies (Skip and Scoot) for its formal scooter pilot and left out early “rogue launch” operators, including Bird and Lime. The decision illustrated a new policy pattern: cities using permits and fleet caps to control deployment, safety, and sidewalk impacts. It also showed how early market entry could create regulatory backlash rather than guaranteed access.
In August 2018, Santa Monica announced that Bird and Lime, along with Jump and Lyft, would operate under a city-run Shared Mobility Pilot Program starting in mid-September. The city used a permit structure, set initial fleet allocations, and required data sharing and operational rules. This was an important shift from “surprise rollouts” toward negotiated, performance-based regulation.
As Santa Monica’s pilot matured, the city adjusted fleet sizes using a performance-based cap system, and the overall fleet grew beyond the initial launch. The city later reported that the combined fleet reached a peak of 3,250 devices by September 2019, reflecting demand and operator compliance under the pilot’s rules. This period captured the boom’s “middle phase,” when cities tried to keep scooters while tightening management of sidewalk impacts and safety concerns.
In March 2020, the COVID-19 pandemic sharply reduced travel in many cities, undermining scooter ridership and revenue. Companies including Bird and Lime cut costs, reduced operations in some markets, and laid off staff, showing how vulnerable the model was to sudden drops in urban movement. The downturn marked the end of the 2017–2020 “boom” phase and the start of a consolidation era focused more on permits, unit economics (profitability per scooter), and fewer operators.
