Superpedestrian has pulled its scooters from Chicago streets.Superpedestrian Scooter-rental company Superpedestrian has left the Chicago market, blaming stiff competition and the city's special relationship with competitor Lyft, which also operates the city's Divvy short-term bike rental service.The Cambridge, Massachusetts-based company told the city last week it had pulled out the last of its 1,000 scooters, according to the company and the Chicago Department of Transportation.Superpedestrian had 12.5% of the city's rental scooters but only 4% of scooter rides since the company launched the service in Chicago in June 2022, CDOT said.The company was one of four companies with licenses to offer short-term scooter rentals. The remaining companies are Lyft, Spin and Lime.

Meanwhile, the company and other rental scooter providers, excluding Lyft, are required to have 50% of their fleet on the South and West sides, where they saw fewer riders. Superpedestrian said about 60% of its scooter trips began in those areas.CDOT did not have an immediate comment on Superpedestrian's claim. Lyft did not immediately reply to a request for comment.Scooter companies have deployed an average of 57% of their fleets on the South and West sides, which the city dubs "equity priority areas," CDOT said in a statement. About 42% of total scooter trips began in these communities, CDOT said, an increase from 23% from the 2020 scooter pilot program.Superpedestrian will now focus on its other main markets: Los Angeles, Seattle and Baltimore, Perkins said.

More than a million trips have been taken this summer, since June 21, CDOT said. That's a 170% increase from the same period last year.The remaining companies have about 6,000 scooters. Lime has 3,000; Spin has 1,500; and Lyft has 1,500 scooters, CDOT said. Lyft's scooters are limited to the greater downtown area.Also Thursday, Lime said its ridership in Chicago is booming. The San Francisco-based company has recorded more than 1 million rides this year.
