Especially in urban contexts, cycling is considered as one of the most sustainable travel options. However, its use is subject to several morphological, physical, cultural and environmental constraints. A lack of knowledge about comprehensive benefits (not limited to the financial ones) from potential users is one of the most critical aspects. To overcome this issue, the project CICLO! develops a calculator of economic performance guaranteed by bicycle compared to other transport solutions. As a first step, the bikeability needs to be evaluated, to verify whether a bike can be considered a valid option for a specific trip. In this contribution, we analyze the metrics adopted by literature to extract a set of Key Performance Indicators that allow understanding whether the minimum conditions of bikeability for a specific user are achieved. The results of our analysis confirm the existence of multi-faceted aspects to be considered within the concept of bikeability, which we included into the following macro-categories: user characteristics, accessibility, security, convenience and possibility of moving. The outcomes of this phase are the basis for the next step, leading to the economic evaluation of the differences between bicycle and other transport options, which makes users informed about the real impacts of their choices and, thus, bicycle a more appealing option.
