This document provides an analysis of the bicycle as an artifact. It describes the 15 main parts of a bicycle, the materials typically used in its construction such as steel, aluminum, carbon, and rubber. It also discusses the different forms bicycles can take, their main function as transportation vehicles, and how physics principles allow them to balance and move forward in a straight line. Finally, it compares bicycles to similar inventions like skateboards and cars, and proposes some potential improvements like fingerprint unlocking and GPS tracking.
