Rocky road ahead for troubled Ofo

Ofo Inc, one of China's largest bike-sharing platforms, is reportedly struggling financially amid rumors of bankruptcy or being forced to sell.

Dai Wei, founder and CEO of Ofo, said in an internal letter on Wednesday: "As winter comes, the storm will hit soon", calling on employees to remain loyal to the company.

Dai sought to rally the company with organizational restructuring and upgrading, establishing three centers for coordinated operation.
