Evaluation of e-bike accidents in Switzerland

•This is the first study to evaluate police-recorded e-bike accidents in Switzerland.•We analysed accidents of the years 2011 and 2012 involving 504 e-bikers and 871 bicyclists. Accidents in different regional environments (rural vs. urban) were compared.•Accident-involved e-bikers were mostly 40–65 years old. Most e-bikers sustained single accidents and helmet usage was higher in the rural than in the urban environment.•The evaluation and comparison of the injury severity of e-bikers and bicyclists lead to diverging results and should therefore be addressed in future investigations. The acceptance and usage of electric bicycles has rapidly increased in Switzerland in the last years. Hence this topic has been addressed by policy makers with the aim to facilitate new transport modes and, moreover, to improve their safety. Police-recorded accidents of the years 2011 and 2012 involving a total of 504 e-bikers and 871 bicyclists were analysed. National figures were compared with those of a rural and an urban environment. Most e-bikers who were involved in accidents were 40–65 years old. It was found that most e-bikers sustained single accidents and that helmet usage was higher in the investigated rural environment than in the investigated urban area. The evaluation of the injury severity of e-bikers, particularly compared to bicyclists, lead to diverging results. The findings presented in this study are intended to serve as a benchmark since basic information on characteristics of e-bike accidents is provided. With respect to differences between the injury severity of e-bikers and bicyclists to-date no clear statement can be drawn. It is suggested to regularly evaluate e-bike accidents to show trends and/or identify changes.
