Trailer Made from a Garage-Sale Bike

  trailer with pedal sticking up in the air

This is a shopping trailer I made in the mid 1990s from a bike I got a garage sale.  The idea was to re-use scrap materials as much as possible while making a highly practical trailer.  Its feature include:
The trailer works pretty well, but has a high center of gravity and so is easy to tip when cornering.

It uses all the members of the original bike frame, plus a light and sturdy aluminum truss stabilized laterally by steel cables.
