Early on, Wilbur Wright made an important discovery about roll: by twisting or warping a wing to achieve a greater angle the more lift occurred on that side. The Wright Brothers alternated between the conceptual and practical application of their ideas to work towards a better understanding flight dynamics. They used the scientific method to first identify the main issues preventing sustained flight and made observations about aeronautics using kites. Like their predecessors in aviation, the Wright Brothers sought to design a controllable machine capable of operating in unstable conditions – similar to how the bicycle works. The Wright Brothers’ bicycle business not only provided funds for their aviation experiments, but also likely helped them acquire mechanical knowledge useful for airplane design. The popularity of their Van Cleve and St.Clair bicycles reflected high public demand for “safety” bicycles, which consisted of two wheels of the same size. In 1895, at the 22 South Williams Street location, the Wright Brothers hand-crafted a small numbers of their bicycle designs. The Wright Cycle Exchange originally operated out of 1005 West Third Street, then moved to 1034 West Third Street, 22 South Williams Street, and finally 1127 West Third Street in 1897. In 1892, the Wright Brothers started another business, the Wright Cycle Exchange, where they repaired and sold bicycles eventually including their own designs. Wilbur later joined his brother in publishing the weekly local newspaper. In 1889, Orville Wright, then a teenager, started a newspaper business, the West Side News at 1210 West Third Street. The Wrights’ parents supported strong family bonds, piety, and intellectual pursuits. Orville and Wilbur’s parents, Milton and Susan Wright, moved their family of seven permanently from Indiana to Dayton in 1884. The Wright Brothers spent their youth in Indiana and Ohio.

This accomplishment represented the inception of modern aviation. On October 5, 1905, Wilbur Wright flew the world’s first practical airplane, the Wright Flyer III, for an unprecedented 39 minutes and 23 seconds at Huffman Flying Field in Ohio. The Wright Brothers used this book along with other aeronautics publications provided by the Smithsonian in 1899 for their early glider designs. However, these inventors’ contributions provided valuable technical aviation information, which engineer Octave Chanute collected and published in his book Progress in Flying Machines in 1894. Although the War Department, likely motivated by the start of the Spanish-American War, commissioned Langley to further develop his aerodrome in 1898, his efforts proved unsuccessful. Around the same time, astronomer Samuel Langley created a steam-powered plane, called an aerodrome. Otto Lilienthal, a German engineer, was the first to create a manned glider capable of sustained flight in the mid-1890’s. Of the three years the ’39 is generally the more desirable due to its double bar frame and unique tank design with the lit reflectors in the side.During the late 19th century, several individuals attempted to invent a heavier-than-air powered flying machine. Like previous years the catalog only list the Zep in black and white although both blue and red bikes with white trim are found as well. While there are small differences between the fenders and other things on the ’39 models the maker (Snyder or CWC) can be determined the same way as a ’38 model although the serial for a CWC bike will likely start with either a “D” or “E”. Like the ’38 models the Zep will have the external fork lock and be fully equipped. Similar models used this frame but the Zep frame will have two holes on the bar under the tank to mount the battery tray (pic) whereas the other models will not have these holes. The frame for the ’39 Zep uses a double bar design. The bikes could also be equipped with either “streamlined” handlebars or “steerhorn” handlebars and also a two speed was available. This fork was optional so you will find Zeps made by both Snyder and CWC equipped with either truss or spring forks. To complicate things even further though Wards sold bikes (not just Zeps) with the, new for ’39, CWC shockmaster fork (pic). For 1939 Wards again used both Snyder and CWC products.
