Electric power-assisted bicycles (e-bicycles) provide a convenient form of mobility in urban areas, being an attractive alternative to private cars, usual cycling and walking. However, there is a growing concern of their associated injuries, resulting from the increasing exposure and apparently higher speeds. Unlike other countries, in Israel, a growing use of e-bicycles by youngsters (below 18) is observed, in many towns, accompanied by a substantial increase in the number of related injuries. In this study, an observational survey of young e-cyclists was undertaken in Israeli towns aiming to characterize their behaviours at typical urban settings and then to consider measures needed for their safe integration in the urban space. The observational survey was focused on teen e-cyclists' behaviours during their trips to and from school and during leisure hours. The data were collected by means of dynamic video-recording, at five types of urban settings: signalized and un-signalized intersections; roundabouts; street sections with and without bicycle-paths. The survey covered 225 locations in 15 cities, including 150 sites near high-schools and 75 in city centers. In total, over 2000 video-films were collected and their contents were coded for statistical analyses. The results showed that at all types of sites, most teenager e-cyclists were males, older than 16 and not wearing a helmet, despite the traffic law demands. High shares of them rode on sidewalks and crossed at crosswalks, violating the law that prohibits using pedestrian facilities for riding. At signalized intersections, substantial shares crossed on red, both on the roadway and on crosswalks, thus violating the traffic law and increasing accident risk. At various urban settings, young e-cyclists demonstrated a wide range of risky manoeuvres. They move faster than pedestrians and endanger them on sidewalks, but also disturb vehicle traffic and endanger themselves while riding on the road. A wider application of bicycle infrastructure, with better separation between the sidewalks, roadways and bicycle paths, would lead to a safer integration of e-bicycles in Israeli cities. Additionally, road safety education and training of teen e-cyclists supported by stronger enforcement of traffic regulations are required.
