when I am packing a bow, arrows and a seat, I don't try prove that I am any kind of a stunt biker. The cheap bike I already have has lasted for years with no damage at all. Although when it is muddy, I walk. If I had really fat tires, I would still walk when it got muddy. The bike I had before, for free, a John Deere lasted for many years. I finally gave it to a college kid. Apparently, he has done the same. For the past ten years various college kids have been riding around town and on the local hiking trail, on my ugly green hunting bike.
