Chinese bike-sharing company ofo celebrated World Car Free Day on Friday, by announcing its planned landing in four more countries.

Ofo plans to enter five cities in the Czech Republic, Italy, Russia and the Netherlands by early 2018, with Prague and Milan the first cities to launch the service. A 30-minute ride will cost 0.5 euro in these two cities. The three other cities will be Moscow, Rotterdam and Groningen.

The company also expanded its services to the Thai tourist resort island of Phuket on Friday, after it entered Thailand in July.

So far, ofo has announced services in a total of 13 countries around the world.

"We are delighted to announce our entry into these countries on World Car Free Day," said Dai Wei, ofo's founder and CEO. "Ofo is devoted to offering green, convenient short trip solutions to every city in the world. We hope people everywhere can ride an ofo and contribute to the protection of global environment."
