Elmore Manufacturing Company was a manufacturer of veteran and brass era automobiles and bicycles (1893–97), headquartered at 504 Amanda Street, Clyde, Ohio, from 1893 until 1912. The company took its name from its original place of manufacture, the nearby village of Elmore. Founded by Harmon Von Vechten Becker and his two sons, James and Burton, the Elmore used a two-stroke engine design, in straight twin or single-cylinder versions. They later produced a straight-3 as well.
The Elmore Runabout was next in line. It could seat two passengers and sold for US$ 800. The vertically mounted Straight-twin engine, also situated at the center of the car, produced 8 hp (6 kW). A 3-speed transmission was fitted. The angle iron-framed car weighed 1400 lb (635 kg).
The top model was the Elmore Tonneau. It could seat four passengers and sold for US$1400. The flat-mounted straight-twin was situated at the front of the car, produced 12 hp (8.9 kW). A 3-speed transmission was fitted. The angle iron-framed car weighed 1500 lb (680 kg).
In 1908, Elmore's three-cylinder two-stroke caught the attention of William C. Durant, founder of General Motors. He purchased the company the following year, with Elmore becoming one of General Motors' divisions. After Durant was forced out of General Motors in 1910, the Elmore marque was soon cut, along with several other underperforming brands, to help General Motors achieve financial stability.
