I have a question about the history of Harley-Davidson. Where did the company start?

The company started in Milwaukee, Wisconsin in 1903. It was founded by William S. Harley and Arthur Davidson, who were both bicycle mechanics. They wanted to build a motorcycle that was reliable and affordable. They also wanted to make it easy to ride, so they designed a bike with a flat handlebar and a single gear. The bike was called the Model A, and it was the first motorcycle to be mass-produced.
