Employing a mixed-methods approach, this study seeks to elucidate the mechanisms underlying e-bike accidents and to develop an e-bike safe system aimed at enhancing e-bike safety and accident prevention. Quantitative analysis was employed to identify key components and their relationships through an event-based examination of a structured accident dataset using a Bayesian network. Complementing this, qualitative methods\u2014including observations and interviews\u2014were conducted to gain deeper insights into how riders interact with other components within the system. This study was carried out in Guangzhou, a metropolitan city with an increasing use of e-bikes and e-bike-related accidents. The key findings of this study are as follows: 1. The safe system of e-bike safety comprises critical components, including infrastructure (roads and facilities), e-bikes, riding behavior, individual riders, and other road users. 2. E-bike accidents predominantly result from dysfunctions of the safe system. The alteration of one component influences other components, which may, in turn, provide feedback to the original component. 3. While riders\u2019 mistakes play a role, the interactions between riders and other components also contribute to the accidents. 4. At the individual rider level, barriers to safe riding include a lack of safety knowledge, low penalties for violations, and high opportunity costs associated with safe riding behaviors. Deficiencies in infrastructure, regulations, and law enforcement contribute to violations and risky riding practices. This study contributes to the current body of accident studies by developing an e-bike safe system.<\/jats:p>","DOI":"10.3390\/systems13040261","type":"journal-article","created":{"date-parts":[[2025,4,7]],"date-time":"2025-04-07T11:24:39Z","timestamp":1744025079000},"page":"261","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Understanding Electric Bike Accidents Through Safe System Approach in Guangzhou, China: A Mixed-Methods Study"],"prefix":"10.3390","volume":"13","author":[{"given":"Bicen","family":"Jia","sequence":"first","affiliation":[{"name":"School of Intelligent Systems Engineering, Sun Yat-Sen University, Shenzhen 518000, China"},{"name":"Guangdong Provincial Key Laboratory of Intelligent Transportation System, School of Intelligent Systems Engineering, Sun Yat-Sen University, Guangzhou 510275, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3062-4140","authenticated-orcid":false,"given":"Jun","family":"Li","sequence":"additional","affiliation":[{"name":"School of Intelligent Systems Engineering, Sun Yat-Sen University, Shenzhen 518000, China"},{"name":"Guangdong Provincial Key Laboratory of Intelligent Transportation System, School of Intelligent Systems Engineering, Sun Yat-Sen University, Guangzhou 510275, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qi","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Intelligent Systems Engineering, Sun Yat-Sen University, Shenzhen 518000, China"},{"name":"Guangdong Provincial Key Laboratory of Intelligent Transportation System, School of Intelligent Systems Engineering, Sun Yat-Sen University, Guangzhou 510275, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,4,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"100182","DOI":"10.1016\/j.multra.2024.100182","article-title":"Integration of e-bikes in public transportation based on their impact, importance, and challenges: A Systematic Review","volume":"4","author":"Olayode","year":"2024","journal-title":"Multimodal Transp."},{"key":"ref_2","doi-asserted-by":"crossref","unstructured":"Zuev, D.
