Compared with work in other European countries, the history of bicycle mobility in Spain is still in its infancy. In pioneering work, some historians have dealt with the nineteenth-century origins of cycling in Spain, particularly its athletic aspects. Other historians have reviewed the main cycling competitions in the country: the Volta a Catalunya, organized in 1911, and the Vuelta a España, begun in 1935. Utilitarian cycling, however, has received less attention. A few authors have highlighted the bicycle’s importance in Spain over most of the century, but none have examined the evolution of utilitarian cycling in Spain during the twentieth century. Although archival sources are ample, their diversity and wide dispersion in various government archives, especially at the municipal level, are research obstacles.
