The European Commission with the active contribution of NTUA, SWOV and KFV has published at the European Road Safety Observatory, the Cyclists Thematic Report which refers to users of a conventional bicycle or a pedelec/e-bike, i.e., an electric powered bicycle offering pedal assistance up to approximately 25 km/h. This Thematic Report describes how cyclists participate in traffic, as well as cyclists in relation to road safety hazards. Furthermore, countermeasures about infrastructure, bicycle-related measures, protective measures, enforcement and traffic education are suggested.
