Alternative transportation companies Bird and Lime have officially announced that they will cease operations in Raleigh by this summer.

Bird scooters arrived in Raleigh over the summer, according to ABC11. Lime, which is partnered with NC State, followed suit with its own scooters. Bird recently raised prices to compensate for city-level regulatory fees.

Sam Reed, director of government partnerships at Bird, announced the company’s leave in a statement to WRAL. The company will be leaving before the end of April, but Reed said that the company may reconsider the city in the future.

“We hope to return in the future when city officials are ready to be more amenable to our business and industry as well as the needs of their constituents,” Reed said in the statement.

Todd O’Boyle, a spokesman for Lime, cited regulations and high fees as reasons for the company’s departure in a statement to ABC11.

“Despite our efforts to partner in good faith, the city has decided to impose some of the most onerous regulations in the country and unfortunately we cannot continue to operate under such restrictive rules,” the statement reads.

The News & Observer reported that while Bird and Lime did not submit required proposals to the city to continue operating after this summer, five new companies did: Bolt, Gotcha, Lyft, Spin and VeoRide.

Michael Moore, transportation director for the city of Raleigh, said that it was important to consider all costs and benefits of these types of vehicles.

“We are excited about the prospects of micro mobility here in Raleigh,” Moore said. “We need to do it in a way that is fair and balanced. That we take care of riders, but that we take care of the other users on the sidewalk and street space.”
