In recent decades, mobility has mainly been shaped by the car in industrialized countries. From today's perspective, this form of mobility seems unsustainable and unfit for the future. Approximately 95% of the worldwide mobility depends on crude oil and hence on limited resources. Therefore, a radical change in mobility behavior is inevitable. Besides this fact, many other problems such as emissions, health problems, lack of space, urban sprawl, decreasing tax revenues and an aging society force us to react. This work deals with on e-mobility as a potential component of a sustainable development and focuses on Pedelecs in Graz. The core of this master thesis consists of a Pedelec-Test carried out among citizens, aged between 40 ? 70 years, from Andritz, a district of Graz, in August 2010. This empiric study was carried out under the technical supervision of Austrian Mobility Research, FGM-AMOR, in the context of the EU project 'Active Access', which is supported by the City of Graz. The study aimed to determine how people can integrate Pedelecs into their daily routines, what kind of experiences they make in doing so and how the use of Pedelecs affects their mobility behavior. Contrary to other electric vehicles, Pedelecs are not in need of additional infrastructure and are ready to go into serial production. The results of the study show that Pedelecs have the potential to replace car for short trips. The results of comparable studies such as "Landrad" Vorarlberg confirm these results. Pedelecs can clearly contribute to further sustainable mobility.However, apparently there exists no singular answer to the question about the ideal form of mobility for the future. Rather, the mobility of the future seems to consist of a mixture of different means of transportation and mobility behaviors. Nevertheless, changes in mobility behavior are needed and electric vehicles could assist these changes without any loss in the quality of life.
