The main idea for this trailer was to have something lightweight but strong to tow behind my bike. At first I was going to use an old rubbermaid bin as the body but decided to use an old sled instead. So I made a strapping frame, screwed it to the sled then cut out a section on each side for the tires (in my case 2 50cc dirt bike tires), found an axle for the tires and screwed them to the frame with steel strapping. I used a ski pole with the handle and the plastic thing on the bottom removed to connect the trailer to the bike. It gets screwed into the wooden strapping on the bottom of the trailer.On the bike it connects to a bent 90 degree bracket under the seat. The bracket is held in with zipties (see picture two). A simple bolt with a cotter pin holds the ski pole to the bracket. The mud guards are both made from a single crazy carpet cut and screwed to the body (it took a lot of adjusting to get it right). The handle for pulling by hand is the same handle that came off the ski pole. A string with a small clip attached goes through the top of it to clip it to the front of the trailer (see picture 8). Thanks for reading. Comments are welcome.
