That's because the 1903 Wright Flyer was barely able to fly a few hundred feet. It was just a proof of concept for stability. The 1904 Flyer II was able to circle and fly for about five minutes. The 1905 Flyer III crashed a few times, and then they reworked the controls and were able to fly 24 miles.

At last, they had a minimum viable product. In 1907 they came out with the Wright Model A, which was the production version of the improved Flyer III. This had a range of 125 miles, and was the first production aircraft.
