The behavior of bicyclists is influenced by infrastructure, weather, other road users, and individual capabilities and preferences. The fundamentally human-powered nature of bicycling indicates that physical capabilities and perceptions of effort may also play a key role in how bicyclists ride, reflecting diverse capabilities and individual choices. Bicycling research has predominantly focused on speed and acceleration, often overlooking detailed behaviors related to perceived effort. The purpose of this study is to examine free-riding behavior --uninfluenced by other road users -- and identify correlations with contextual features such as infrastructure design (horizontal and vertical alignment) and wind speed. We introduce a method using instrumented bicycles in a semi-controlled experiment to collect detailed data on free-riding behavior, including speed, power output, and heart rate. Participants use their own bicycles equipped with sensors on designated routes and complete a survey to assess their experience and perceived effort. Experiments conducted in Germany and Sweden allow for comparative analysis of different infrastructure designs.
