What metaphors are used in Civil Peace by Chinua Achebe?

A bicycle becomes a metaphor for financial survival. Jonathan owns a bicycle that represents a considerable ability to transport heavy loads of goods or cover long distances with relative ease. Jonathan uses his bicycle to make small amounts of money transporting things for other people. In early 1969 he realizes that his bicycle will eventually be stolen because of the civil unrest accompanying the civil war. He therefore buries his bicycle in a camp graveyard where it stays for about one year. After the end of the war Jonathan digs up his bicycle and finds it no worse for the wear.
