If you were ever wondering how to make a trail from a bmx trail or dirtbike trail, this would be the guide for you. Usually when you start a trail you want to find a nice hill filled location to start. Usually bike trials have challenges to overcome, ranging from jumps, to sharp turns. Work on removing shrubs and flattening hills and making the jumps to your liking. Add challenges to your course, make it hard for others and you. If you have the time, make it wider, faster, more dangerous and have fun with it. Once you have a long enough trail, test it, if you like it great! Invite some friends to test it with you and enjoy your new trail.
