While shared e-scooters are still highly prevalent in many urban areas, we also see an increasing share of privately owned e-scooters on our roads. However, so far, not much is known about the users of such privately owned e-scooters. As there is reason to suspect that those who ride their own e-scooter differ considerably from occasional users of rental vehicles, the question is what the characteristics of those riders are and how their use of vehicles can be described. To address these questions, we analysed data from an online survey (99 usable data sets) and several focus group discussions (20 participants) with frequent users and owners of e-scooters. Results show that these frequent riders have a high degree of identification with the vehicle, and often use it as their main means of transport. The majority indicated that they used their e-scooter daily or almost daily, with commuting as their most frequent trip purpose. They are rather safety conscious, as is highlighted by their use of protective gear and the installation of additional safety equipment on their vehicles. The results indicate that a specific focus on frequent users is warranted, as they appear to be quite distinct from the user population that occasionally uses shared services. With the number (and share) of privately owned e-scooters continuously increasing, targeted approaches that facilitate their safe and efficient participation in traffic will be required.
