Other forms: spokes
A spoke is a bar or rod that connects the center of a wheel to its rim. The purpose of spokes is to support the structure of the wheel. You can jazz up your bike by weaving ribbons between the spokes.
Originally, spoke meant "a piece of a split log." When wagon wheels were made of wood, they were formed using these spokes, which were carved into matching shapes. Wheels with spokes were invented around 2000 B.C.E. or even earlier, and they revolutionized travel, making vehicles lighter and faster. Experts believe that spoke shares a root with spike.
