In my riding areas, there are a couple of terrain features that include about an 80 ft. hill. The average slope is probably about 45 to 50 degrees. TOO steep to push a bike up. I'm going to get some kind of winch or pulley system with rope to pull a dead/broken bike up one of these hills. I don't plan on carrying it with me when riding but just having it at the cabin, an easy walking distance away. I'd also always be able to find at least 1 helper to help recover a bike. I just don't know what kind of winch or pulley system is suitable for what I'm doing. Has anyone had experience with doing this? I know that at least one location I'd never get any vehicle near the top of the hill, so I'm thinking some kind of manual set up.
