Rider-Lewis was a brass era automobile built first in Muncie and then Anderson, Indiana from 1908 to 1911.^[1]

Ralph Lewis of Boston, designed an overhead valve, overhead cam six-cylinder engine of 40/45-hp. George D. Rider financed manufacturing and the Rider-Lewis Motor Car Company was established. Rider-Lewis introduced the automobile at the Indianapolis Motor Show in March 1908 priced at $2,500 (equivalent to $84,778 in 2023). Production began in Muncie in a converted factory, though in 1909 the company moved to a newly built factory in Anderson, Indiana.^[1]

For 1910 the "Excellent Six" was joined by a four-cylinder Model Four automobile selling for $1,050, equivalent to $34,335 in 2023 . In September 1910 the company was in receivership, though production continued. In October the Rider-Lewis property in Anderson was attached by court order when creditors thought Rider-Lewis was preparing to move out of state. A few more Model Fours were built into early 1911, but by March the Rider-Lewis plant was sold to Nyberg Motor Works.^[2][1]
