Tecent Holdings Ltd and Warburg Pincus led a $215 million round of funding for year-old Beijing startup Mobike, ratcheting up the competition in China's burgeoning urban bicycle-sharing scene.

The round brought in a clutch of new, influential names including private equity firm TPG Capital, Chinese travel service Ctrip.com International Ltd., and Huazhu Hotels Group. Existing backers Hillhouse Capital, Sequoia Capital also took part in the financing, Mobike said in a statement. They will work together to help travelers get around Chinese cities, the startup added.

Once emblematic of China's socialist working class, bicycles remain popular among students and urban commuters despite rapidly growing car ownership. Mobike is among the largest of a growing crop of private bike-sharing operators, known for its distinctive orange-hued and GPS-equipped bikes.

The industry is drawing hundreds of millions of dollars from investors betting that bicycles offer a more traditional alternative to the car-hailing that prevails in urban centers. One of Mobike's largest rivals, ofo, is said to be valued at $500 million after attracting investment from Xiaomi Corp. founder Lei Jun and Didi Chuxing, which ran Uber Technologies Inc out of China in 2016.

Formally known as Beijing Mobike Technology Co., the startup has said it operates about 30,000 bicycles spread across the major cities of Beijing, Shanghai, Guangzhou and Shenzhen, which together house more than 74 million people. It aims to stock at least 100,000 bikes in each city and expand to other cities. Ofo says it has more than 85,000 bikes, mostly on university campuses, and expects to take its service to other Chinese locales.

Both are eyeing markets in Europe. There are about 600 bike-sharing operations globally, with a market that could grow by 20 percent a year to generate as much as $5.8 billion in revenue by 2020, according to consultancy Roland Berger.

Mobike didn't disclose its valuation after the latest funding round.
