## 2 Literature Review  
Sustainable mobility can be characterized by the formed communication behavior of users in a spatial structure and transport, while individual car transportation does not degrade public and non-motorized transport [1]. The number of bicycles shared in the world using bike-sharing services has already reached above 9 million [6; 7]. The states' reasons for supporting bicycle transportation comprise four categories:  
* Economics;
* Ecologic;
* Medical;
* Social reasons. Recent studies dealing with the issue of examining the impact of public bike-sharing systems on mobility approaches the problem from different perspectives, such as an overview of approaches to introducing the bike-sharing system [8; 9], a general framework of the existing bike-sharing services [10; 11; 12; 13], accident rates and safety [14; 15; 16; 17; 18], the environmental impact [19; 20], a sociometric survey of users of the service [21; 22; 23; 24], and an examination of the service's reachability [1; 25; 26; 27; 28]. Each of these perspectives represents a factor impacting the success of introducing the bike-sharing service. These can be summarized follows:  
* overview of bike-sharing system implementation,
* framework of existing services,
* accident and safety studies,
* environmental impact assessments,
* sociometric user surveys,
* reachability, and accessibility studies. Environmental benefits are among the most common factors or reasons for introducing the bike-sharing services because of reducing greenhouse gas emissions [29; 30; 31]. However, these environmental benefits largely depend on the actual replacement of car trips by bike-sharing, which leads to the assumption that the high interest in the bike-sharing service can replace car trips [29; 30; 32]. For example, evaluations of the Chinese bike-sharing system have demonstrated significant environmental benefits, where authors [29] estimated annual savings of 25,240 tons of CO\({}_{2}\) and 64 tons of NOx emissions. Even more significant is the evaluation of the bike-sharing system in Beijing, where a reduction in CO\({}_{2}\) emissions of 616,040 tons in 2015 was estimated [33]. However, these estimates assumed a high rate of car replacement by bike-sharing. Bike-sharing service development also has the potential for health benefits, promotes active travel, and increases physical activity levels [27; 34]. Moreover, the health benefits of increasing physical activity outweigh the risks of traffic accidents and exposure to harmful air. An analysis of the New York City bike-sharing system revealed it as the most cost-effective preventive tool for public health [35]. This also relates to the alleviation of traffic congestion in cities. [PERSON] et al. [36] measured the impact of bike-sharing on traffic congestion in 96 urban areas in the USA and calculated differences before and after the introduction of bike-sharing, then between urban areas with and without bike-sharing service, using annual congestion statistics. The service could enable significant economic benefits through reduced travel times. The data analysis of bike-sharing service in Lyon (France) showed 68.2% of bike-sharing trips are shorter than travelling by car, resulting in an average distance reduction of 13% [37]. Furthermore, [PERSON] et al. [38] estimated a 20% reduction in travel time due to using the bike-sharing service in London (United Kingdom). Then, sufficient cycling infrastructure is directly related to higher safety for cyclists on the roads. Poor safety and infrastructure could represent an important reason for reluctance to use bicycle transportation in general [39]. There are many problems related to cycle infrastructure in the Slovak Republic. Several cities are missing coherent and continuous cycle paths, which limit cyclists from moving smoothly between destinations. However, local governments are trying to support the construction and renewal of cycling infrastructure, although these measures have not yet resulted in a fully connected network [2].
