This study aims to explore users' preferences for shared bikes, obtain the cognitive gap between designers and users on products, and output corresponding design decisions to provide inspiration and reference for product innovation in shared bikes and two-wheel bike industry. From the perspective of designers' thinking and consumers' preferences, the design principles (attributes) of consumers' preferences for shared bikes are classified carefully, 8 evaluation dimensions and 41 evaluation features are established, and the KANO model is used to conduct quantitative statistics and qualitative analysis of effectively collected samples. Based on the preliminary investigation and KANO model analysis, relevant strategies for bike design in the post-bike-sharing era are proposed. In the post-bike-sharing era, designers need to study design strategies based on users' real product preferences and perceived experience, so as to design products that truly meet users' needs and experience expectations. This study also proves that KANO model, as a method to clarify different perceptual needs of users, is helpful for designers to make comprehensive judgment of design decisions and improve the competitiveness of design.
