Abstract: Many issues arise in the rapid development of shared bicycles caused by the sharing economy， which poses a severe challenge to the sustainable development of bicycle sharing. Based on the dual perspectives of user experience and technological innovation， this study incorporates consumer innovation， perceived enjoyment and peer influence into technology acceptance model (TAM)， and constructs a model for the research on consumers' willingness to use shared bicycles continuously. The empirical results show that consumer innovation has positive impacts on perceived ease of use， perceived usefulness and attitude towards using shared bicycles. Perceived ease of use and perceived usefulness play multiple mediation roles in the impact of consumer innovation on attitude towards using shared bicycles. Peer influence has a positive impact on consumers' attitude towards using shared bicycles. Perceived enjoyment has a positive impact on consumers' willingness to use shared bicycles.

Key words: consumer innovation, peer influence, perceived enjoyment, technology acceptance model(TAM)
