Washington • Motorized electric bicycles may soon be humming onto serene trails in national parks and other public lands nationwide. It’s part of a new Trump administration order — hotly opposed by many outdoors groups — that will allow the so-called e-bikes on every federal trail where a regular bike can go.
Sales of the bikes, powered by both pedals and battery-driven small motors, are booming, and some aging or less fit people have sought the rule change. It will allow them to whirr up and down biking trails in the country's roughly 400 national parks and other federally managed backcountry areas.
