The largest ride-hailing service in China just made a big investment in a different kind of transportation program: bicycle sharing. According to a report from TechCrunch, DiDi Chuxing is kicking off a "multi-layered partnership" with Ofo -- an app-based bicycle sharing outfit with a network of over 70,000 bikes in 20 cities. The details of the investment are pretty bare, but DiDi Chuxing says the companies will "explore strategic cooperation in urban rideshare, including offering a quality bike-sharing experience on DiDi's platform." In other words, the company's ride-hailing app may include a bicycle rental option in the near future.
