Since the end of 2016, bike sharing has suddenly taken off in China. According to the 2016 Chinese bike-sharing market report, total user numbers for bike sharing have reached 18,860,000. The bike brands used for bike sharing include Mobike, Ofo and at least 25 other new bike-sharing brands. Specifically, Ofo bicycles occupy the largest proportion of the Chinese shared bicycle market, contributing 800,000 shared bikes with a market share of 51.2%. Mobike occupies the second-largest proportion of the Chinese shared bicycle market, and has contributed 600,000 shared bikes with a market share of 40.1%. Meanwhile, the competition in the bike-sharing field has become fierce, and operators have taken steps to begin large-scale expansion. Under these conditions, bike-sharing users’ behaviour, especially their intention to recommend bike-sharing apps, becomes particularly important as Morin (1983) indicated that other people’s recommendations are three times more effective than advertising. Specifically, bike-sharing app refers to one app, such as the Mobike app. When users want to ride the shared bike, they must pay a deposit first, then make a payment, and after that scan a two-dimensional code to unlock and start riding the bike.
