Is Electric Loud? Comparing Noise from Traditional and Electric Bicycles in a Quiet Setting

Electric bicycle use in parks and recreational trails throughout the United States has been increasing in popularity, requiring management considerations. One of these considerations is the noise associated with e-bikes, yet little is known about how this noise may differ from traditional bikes and influence the acoustic environment. This study sought to measure and compare the extent and amount of noise that both traditional and e-bikes can contribute to an environment. Results show a range from no perceptible difference to a readily perceptible difference based on bicycle type (traditional, Class I e-bike, and Class II e-bike) and speed, with the largest difference being between a traditional bicycle and Class II e-bike at lower speeds. Understanding disturbances to the acoustic environment will provide decision makers with information on how to minimize impacts to acoustic resources and visitor experience, while maintaining access to recreation to park visitors.
