China's ride-hailing app Didi Chuxing announced on Monday it has invested "tens of millions of dollars" in Chinese bike-sharing startup called ofo.

Apart from already covering cars, taxis and commuter buses, Didi, which recently bought Uber's China business, wants to take a look at two wheels also as part of its plan to develop a transport ecosystem.

"If it's only two or three miles away, or the traffic is crowded, I can just ride a bike and go," Liang Sun, Didi's spokesperson, said.

The two companies, however, did not disclose the specifics of the deal.

Ofo initially was a student project in 2014 in China's prestigious Peking University. The bike service, which is founded by college alumnus Dai Wei, now has about 70,000 bright yellow-colored bikes in different campuses across 20 cities. It also claims to have 1.5 million users and handles half a million rides each day, Tech in Asia reported.

The service is run via an app for iPhone and Android. Ofo works via Tencent Holdings Ltd.'s WeChat, where users scan a code from their smartphones to unlock parked bikes and go to their destinations, according to Bloomberg. Payments that cost to as slow as 0.5 yuan ($0.075) per ride can be made through the messaging app.
