Beijing Mobike Technology Co Ltd on Wednesday announced it is expanding its business links with WeChat, China's largest social networking platform, in a move that will allow the bike-sharing startup to access the latter's huge user base.

As part of efforts to outshine its rival ofo Inc, Mobike said users don't have to download its app to enjoy bike-sharing services. Instead, WeChat will also give its users quick access to Mobike services in its WeChat Wallet function.

Although it is labeled an option for "limited time", there is no indication of when it will expire. Currently, WeChat has about 889 million monthly active users.
