  • With the recent revitalization of the shared economy, bike-sharing services are gaining huge popularity in the bicycle sector. Bike-sharing services are characterized by reducing environmental pollution and borrowing bicycles at low prices. This study investigated the mechanisms for the formation of customer's continuance intention toward bike-sharing services. The theoretical framework clarified the role of perceived value and trust in enhancing customer's continuance intention. Perceived usefulness, perceived ease of use and perceived enjoyment are considered as the vital factors of enhancing perceived value and trust in a service provider. The research model was validated by data from 217 bike-sharing users in China. Both perceived value and trust in a service provider had a significant impact on user's continuance intention. However, the analysis results showed that perceived usefulness does not have a significant impact on both perceived value and trust in a service provider. Perceived ease of use and perceived enjoyment played a significant role in enhancing both perceived value and trust in a service provider. Our results are expected to provide academic and practical implications for bike-sharing services.

  • This study investigates structural and vibration analyses for three types of bike frame fork models. As long as the maximum equivalent stresses of these models are lower than the yield stress, the three models are considered to be safe structurally. Type 3, with a maximum equivalent stress of 169.23 MPa, has the lowest stress among the three models and the strongest strength. Types 1, 2 and 3 have natural frequencies lower than 270 Hz. Type 3, with a critical frequency of 118 Hz, has the best durability under vibration among the three models. In order to decrease the vibration transmitted to a bike rider riding on a rough road, the impact due to vibration can be relieved by selecting a Type 3 model from among the three models. The results of this study can be effectively utilized for the design of a bike frame fork as this allows the anticipation and prevention of damage caused by durability issues.

  • This study investigates structural durability through the analyses of stress, fatigue life and vibration damage at bike carrier basket. As model 2 has less stress and deformation than model 1 on static structural analysis, model 2 becomes more durable than model 1. Among the cases of nonuniform fatigue loads, 'SAE bracket history' with the severest change of load becomes most unstable but 'Sample history' becomes most stable. The amplitude deformations become highest at maximum response frequency of 2400Hz in cases of models 1 and 2. As the values of maximum equivalent stresses become within the allowable material stresses at two holes at the upper parts on models 1 and 2, these models become safe. The structural result of this study can be effectively utilized with the design of bike carrier basket by investigating prevention and durability against fatigue or vibration damage.
