I am a 59 year old cyclist who rides some technical trails. I have to practice and develop my fitness and technical skills to both climb and descend the trails. I do not want some beginner on an E bike ruining my trails and endangering themselves and others. The fact that the trails near me have some tough climbs helps keep my trails from being over run. I do not endorse E bikes on any single track in my area. If someone is too debilitated to get on a bike , they should not be out bombing thru single track on a POWERED vehicle. E bikes are here and not going away.
