Integrative Bicycle Helmet Fit

Bicycle helmets can reduce head injury in the event of a crash. However, an improperly fitting helmet may move out of its intended position, exposing parts of the rider’s head and increase the risk of head injury. In published research, bicycle helmet fit is defined infrequently and inconsistently. In addition, a research study may explore one or two components of fit, yet describe their study holistically as bicycle helmet fit. In response, a literature review was conducted on bicycle helmet fit and includes other relevant aspects of fit from other industries and applications. This paper operationally defines and describes bicycle helmet fit, integrating the concepts of (1) perception of fit, (2) static fit, and (3) dynamic fit. Finally, an integrated approach to helmet fit should benefit future research, as well as the design and development of future safety countermeasures for cyclists.
