e-bike and e-scooter accidents over a span of three years, and China found a four-fold increase in injury rate and a six-fold increase in mortality rates. However, significant gaps remain in the knowledge about the safety measures and impact of e-scooters. A particular cause of accidents is the instability of vehicles with such small wheels when, for example, hitting a pothole. In Holland there are scooters with large wheels, like bicycles with a standing platform instead of a saddle. As e-scooters become more popular in urban and high traffic settings, user safety poses a major concern alongside other health risks for drivers, pedestrians, cyclists and other vulnerable groups such as the elderly and children sharing the road. A study conducted in China assessed risky behaviors of e-bike, e-scooter, and bicycle riders at crossing signalized intersections and found three different types of risky behaviors including stopping beyond the stop line, riding in motor lanes, and riding against traffic. The same study found that those riding e-scooters are more likely to engage in risky behaviors. In specific, e-scooter riders were more likely to ride in motor lanes and ride against the flow of traffic through there is high variability in the types of accidents that occur and can vary based on time of day. Understanding the health impacts of e-scooters should be considered when developing standards and policies for these new but prevalent modes of transportation. For example, policymakers should highly consider whether electric bicycles and e-scooters belong in bicycle lanes, car lanes, or on the roadways at all. Underreporting poses as additional gaps in knowledge, as minor crashes, for example, tend to be underreported and thus unaccounted for in overall e-scooter injury prevalence and there exist gaps in research on injuries related to e-scooters. Scooter-sharing systems such as Lime or Bird include safety precautions on the scooters themselves, such as: "helmet required, license required, no riding on sidewalks, no double riding, 18+ years old". Apps used to unlock and rent the scooters will also have safety reminders and ask the riders to abide by local laws while using them. However, these recommendations are not always followed, and the difference in laws between cities and states makes regulation difficult. A consumer association in Belgium tested e-scooters, concluding that a bicycle was preferable, citing many problems with the devices, including in particular battery failure and very poor braking in wet conditions. E-scooters were
