Why is the invention of the bicycle considered a relay race of innovation rather than the work of one nation?

Answer

Because different countries contributed essential mechanical advancements over nearly a century

The history of the bicycle shows that no single nation is solely responsible for its creation. It was a cumulative process: the concept of two in-line wheels appeared early; then Germany contributed the vital mechanism of steering with the Draisine; France later provided the breakthrough of direct pedal propulsion with the velocipede; and finally, Great Britain solved the problems of stability and safety with the chain-driven Rover Safety Bicycle. Each nation added a necessary, incremental engineering correction that built upon the work of others, resulting in the modern bicycle seen today.
