The subculturalization process is mainly associated with social actors who use music or winding for a football club as a basis for creating their own lifestyle and identity. Less known is that kinesiological activities or a sport can serve young people as a basis for creating subcultural style and identity. Except in one part of the academic community (mostly abroad), there is no research of subculturalization process based on kinesiological (or sport) activities in this region. Although in few national studies of youth subcultures, we can find terms which refer to this process (Perasović, 2001), at the same time among young people, in their everyday communication, we can often find terms that indicate the identity of "bikers", "snowboarders", "skaters" and the other, parallel with terms such as "punks", “football fans "or" clubbers ". How a young man becomes a " biker”, what is the connection between kinesiological activities and subculturalization process, will be the main theme of this dissertation. The previous observation and knowledge of the "BMX scene" in Zagreb provides insight into the process we want to explore. According to scientific research tradition in this area, ethnographic method seemed most appropriate for obtaining relevant data. This research therefore supports and extends some of the conclusions drawn by other scholars who have investigated this specific case (Rinehart, 2008, Wheaton and Thorpe, 2011, Wheaton 2019). The cultural politics within this group is unique, based on a distinctive history, ideology and identity. Lifestyle sports provide an important lens for understanding the empirical and theoretical trajectories and challenges of sport in the twenty-first century. This research provides valuable information about local BMX riders’ attitudes to the commercialization of lifestyle sports, and their inclusion in the Olympic Games. In their efforts to fast-track the inclusion of action sports into the Olympic program, the IOC (International Olympic Committee) incorporated them with little knowledge of the unique cultural values or practical requirements of lifestyle sports participants. Many participants see a potential loss of autonomy within the Olympic structures. However, since BMX is still not well known in Croatia, the riders see the benefits of inclusion only in the popularity and progress of the sport itself. While the marriage between action sports and the Olympic Games will certainly add to the popularity of BMX worldwide, it can be assumed that there will be a further rift within the BMX scene given that the Olympics exclude the core and genuine values of lifestyle sports, at least from the perspectives of riders. This methodological approach can help shed further light on the complex dynamics of commercialization in lifestyle sports.
