By Charles Pekow — Electric mountain bikes don’t seem to affect terrain or wildlife much more than conventional mountain bikes. But more research is needed on the topic, concludes the first study of eBikes on federal lands. The U.S. Department of Transportation reported on the issue following a 2019 order by the Interior Department to develop policies to allow eBikes in lands operated by the Bureau of Land Management, National Park Service, Fish and Wildlife Service, and Bureau of Reclamation.
The report also states that the nation needs to conduct more research into possible effects of eBikes on cultural and historical facilities. On the plus side, it says riding eBikes in public lands can reduce use of autos and thus cut emissions. It suggests adding charging stations. Injury levels are about the same between users of both types of bikes, but eBike users tend to be older and suffer more head trauma.
