The increased popularity of cycling in Poland has given new prospects for interdisciplinary research. This enabled multifaceted analysis of recreational activity based on a network of bike trails. One such well-functioning and well-managed network is the Wielkopolska System of Bike Trails which is especially popular in the Poznań agglomeration. The aim of this paper was to present pre-developed methods for analysing a network of bike trails in terms of physical activity and recreational attractiveness as well as to present preliminary results concerning an exemplary trail. The obtained results will enable further development of the methods in order to quite a vague statement make them more precise. Then, the methods will be used to analyse a landscape, trails, and cyclists in order to create a targeted tourist and recreational offer for the Poznań agglomeration based on the Wielkopolska System of Bike Trails.
