I was commissioned to make an outdoor sculpture using bike parts for a birthday present.  After a few trips to the dump, ebay and elsewhere, I had my parts.

The top part is the Chinese Character for his astrological sign with bike spokes skewered into metal flashing.   

The center is a 'time capsule' of very old bike parts stuffed into a round found object and held in by chicken wire. There is a large outer ring, (also found) and two bicycle chains welded on the outside edge.

The bottom part has two Chinese Characters on it. The first is the symbol for 'Peace'.  The second is the symbol for 'Good Luck'. ( the most widely used symbol for a home).  I have stuffed the flashing with close to 400 spokes, most of them have the 'nipple' screwed onto the ends of them.
