Researchers at the University of California San Diego have found that injuries involving electric bicycles, or e-bikes, have increased dramatically across California, rising from just two reported collisions in 2018 to 1,506 in 2024. The study, "An Exponential Increase in e-bike Injuries in California," published in Trauma Surgery and Acute Care Open, also found that e-bike riders were more likely to experience moderate-to-severe injuries than riders of traditional bicycles, highlighting growing public health and safety concerns as e-bike use continues to expand statewide.
