Abstract
Naturalistic cycling studies can be performed by making instrumented bicycles available to participants, or by having mobile equipment added by the participants themselves to their own bicycles. This paper describes how participants' bicycles can be equipped with a commercially available, small and unobtrusive action camera to gather naturalistic cycling data. Lateral position, swerving and speed were analysed using video and GPS to assess cycling behaviour of older cyclists, and to assess the influence of different types of cycling infrastructure. The applied method gathered insights in possible interventions in a cost efficient way, inconspicuously, and quickly, compared with instrumented bicycles. Also, several bicycles can be instrumented at the same time with as only limitation the number of cameras available.
