It's fairly lightweight, and as a neighbor put it, "looks bad as hell." (Not my line, but I agree!)
It took a few months to complete, working on and off. It was painted to match an old 10-speed that I restored for my wife, and has upholstered seats, covered wheels, and a trunk to carry lunch for the family.
This open-top design works well for the age of my child, but the techniques I used to make this could be applied to make a similar child trailer in almost any form, such as to accommodate a sleeping baby, or to included some kind of canopy, for example.
Thanks for taking a look . . . and as always, let me know what you think!
Step 1: Old jogging stroller
The rear wheels are attached to a flat piece of metal that is bolted to the stroller frame. This wheel assembly worked out perfectly for what I needed, as did the handlebars which were modified to use as the tow bar.
