A week ago, I saw a guy in our small Kansas town pushing a shopping cart filled with his belongings. He needs this bike trailer, and I want him to have it.
I bought a used InStep bike trailer from The Recyclery, a used bike shop. $40. Kinda pricy, but I think they're doing a service for the community by fixing up and selling used bikes. Generally I can get these trailers for between free and $25.
Used bike trailer $40
Cedar wood fence pickets from HD $8.91
Scrap wood for the underside of the trailer
Bolts, nuts, washers $6
The whole thing cost less than $50.

Step 1: Design
I cut 2 pieces of scrap plywood the width of the trailer and bolted them in to the plywood as pictured. Then I cut cedar planks to lay across the plywood. I polyurethaned the cedar planks, and screwed them into the plywood pieces, using the existing holes whenever possible.
Step 2: More Design
I then cut down some 2 X 4's the width of the trailer frame, about 1 1/2" wide, and bolted them through to the underside pieces. Then I took some of those slices of 2 X 4's and used them as the uprights for the sides of the utility trailer. I then took some of the same 6" picket fence cedar pieces that I used for the deck and I ripped them in half and used them for the sides of the utility trailer.
Step 3: Side Rails
The back of the trailer will be removeable.
I added 4 screw eyes to the trailer so that bungey cords could be used to hold down valuables.
This will come in handy for people who use their bike for transportation.
Step 4: Finishing Touches
I added 4 screw hooks for storage. Also I added corner clamps to hold the edges together. Polyurethane is next.
The back side is removable.
