Updated 2025 First, I’ll say I think that e-bikes have a place, and open up “biking” (e-motor biking) for a number of people that could not do it or enjoy it as much (or at all) on an bicycle or non-motorized adaptive bike. And of course to some their ebike is more fun than their

I’m not sure how many people in the trail industry or volunteer front visit Trailism, nor how many know about the Trail Eaffect podcast, but if it’s new to you I suggest you give it a listen. It’s been a neat and fun learning resource that has been listed on the resource materials page for
