Uber-Backed Electric Scooter Rental Firm Lime Files for IPO

(Lime)

Electric bike and scooter rental startup Lime filed for an initial public offering, showing growing revenue and an expanding user base.

The company, which is incorporated as Neutron Holdings Inc. and backed by Uber Technologies Inc., had a net loss of $59.3 million on revenue of $886.7 million in 2025, compared to a net loss of $33.9 million on $686.6 million of revenue a year earlier, according to its filing May 8 with the U.S. Securities and Exchange Commission.

Lime was previously valued at $510 million in 2020, when Uber led an investment round in the company with participation from Alphabet Inc.’s Google Ventures and Bain Capital Ventures. The figure was a sharp drop from 2019, when a funding round valued Lime at $2.4 billion. Lime is seeking to list at about a $2 billion valuation, the Financial Times reported, citing people familiar with the matter. The company declined to comment to the paper.

The San Francisco-based micromobility firm was founded in 2017 and offers short-term electric bike and scooter rentals in more than 230 cities. It first floated IPO plans back in 2021.

Lime has expanded aggressively in recent years, launching in more than 20 cities including Tokyo and Athens. The company’s distinctive green bikes are ubiquitous in London, where it saw usage spike during a Tube strike last year. Lime had 3.8 million monthly active users in 2025, up 21% from a year earlier.

Uber Freight ranks No. 16 on the Transport Topics Top 100 list of the largest logistics companies in North America.
