Worcester introduced the bikes to the city last year , becoming the first East Coast city and only the second city in the country to adopt the ofo bikes. Revere also experimented with the bikes last year but has not had any contact with the company this year.

Bringing to an abrupt end its bike-sharing service, which proved popular but also susceptible to vandals, ofo is pulling its bikes out of Lynn, Quincy, and Worcester, the only three Massachusetts cities where the company operated this year.

A dockless bike-sharing company known for its bright yellow design is deflating its fleet in Massachusetts.


“As we continue to bring bikeshare to communities across the globe, ofo has begun to prioritize operations in a number of successful markets, allowing us to continue to serve our customers at the high level of quality they have come to expect,” Andrew Daley, ofo’s head of North America, said in a statement.

A spokesman for ofo did not say whether the reduction in Massachusetts is part of a larger decrease in ofo bikes nationwide.

In Quincy, the city plans to transition its dockless bike-sharing program to another company, Lime, “after ofo announced a dramatic reduction in its North American operations,” according to a statement from the city. All ofo bikes in Quincy are expected to be removed by the company by Friday, and Lime is expected to start its Quincy operations in early August.

“The people of this City showed a great affinity for dockless bike sharing over the past few months,” Quincy Mayor Thomas P. Koch said in a statement, “and we believe that Lime will be able to provide a long-term solution to those last-mile commuting challenges here in Quincy.”

Not everyone has used the dockless bikes correctly, though. Over the last several weeks, many bikes have been found underwater. At least four — two owned by ofo and two owned by LimeBike — were found in waters in Arlington, Quincy, and East Boston.


In Quincy, police pulled two ofo bikes from the water at Houghs Neck Maritime Center at the end of June.
