The U.S. Forest Service manages most of the trails in the San Bernardino National Forest, but its budget doesn’t account for all of the trail work needed annually. Without regular maintenance, trails may fall into disrepair and become unusable, and potentially harmful, to the natural environment. To assist the Forest Service's trail maintenance efforts, the San Bernardino National Forest, City of Big Bear Lake, San Bernardino County, Big Bear Mountain Resort, Southern California Mountains Foundation, and Big Bear Valley Trails Foundation have united to form the Trails Advisory Group, which is dedicated to improving non-motorized trails across Big Bear.

Ebikes are a great option for beginners, riders with physical limitations, or anyone looking for a boost while riding from uphill ascents to all-day expeditions. rich-text, responsive-table
