Sample weights were determined by NEISS using factors that influence likelihood of selection such as hospital size and geographic locations.

The number of fractures and admissions increased by 2371% and 3146% in 2023, respectively, compared with 2019. Collision with a motor vehicle occurred in nearly one-fourth of fractures, and motor vehicle involvement was significantly associated with hospital admission (36.4% vs. 25.1%;\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = 0.01). Overall, 27.7% of e-bicycle fractures were admitted to the hospital. Upper leg fractures had the highest association with admission (90.7% admission rate) but only consisted of 2.7% of all fractures. The most common fracture location in riders younger than 18 years was the wrist, while the 35\u201355 age group and older than 55 years group were most likely to possess upper trunk fractures (cervical spine, thoracic spine, ribs, and sternum). The 18\u201334 age group and 35\u201355 age group most commonly sustained fractures involving motor vehicles (29.7% and 28.7%, respectively), but the 35-55 age group possessed a significantly higher rate of overall admission among all age groups (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = 0.04).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>CONCLUSIONS:<\/jats:title>\n                    <jats:p>There has been a substantial increase in fractures and resource utilization as a result of hospital admissions from e-bicycle riding from 2019 to 2023.
