Full Answer

Inventing and patenting anything was a significant and challenging accomplishment for African-Americans before the Civil Rights movement that started in 1954 in the United States, but Isaac R. Johnson was not the only inventor to have received this type of recognition. Other African-American inventors who worked prior to 1954 included George Washington Carver, Garrett Morgan, Elijah McCoy and Jan Matzeliger, who each made considerable technological developments.

The precursor to the bicycle was made in Germany in 1817 by Baron Karl von Drais, and it was called "draisine" in English. This invention lacked pedals until the 1860s, which was when the machines were given cranks and pedals that propelled the vehicle's front wheel, bringing to the world the more commonly recognized form of the bicycle.

A bicycle is a velocipede. This means that it falls under the category of human-powered inventions such as the unicycle and the tricycle.
