I want to started traveling with my bike (26" full suspension mountain bike) and my large 38" tall backpack next spring. I am looking for a way to hall the pack. I have come up with one idea and that is to make or buy a cart (one or two wheels) to pull behind the bike. I figure that would keep the weight low to the ground so as not to effect the balance of the bike so much. Does any one here know of a good premade or homemade one or a better idea?
