Singer Motors Limited was a British motor vehicle manufacturing business, originally a bicycle manufacturer founded as Singer & Co by George Singer, in 1874 in Coventry, England. Singer & Co's bicycle manufacture continued. From 1901 George Singer's Singer Motor Co made cars and commercial vehicles.

Singer Motor Co was the first motor manufacturer to make a small economy car that was a replica of a large car, showing a small car was a practical proposition. It was much more sturdily built than otherwise similar cyclecars. With its four-cylinder ten horsepower engine the Singer Ten was launched at the 1912 Cycle and Motor Cycle Show at Olympia. William Rootes, a Singer apprentice at the time of its development and consummate car-salesman, contracted to buy 50, the entire first year's supply. It became a best-seller. Ultimately, Singer's business was acquired by his Rootes Group in 1956, which continued the brand until 1970, a few years following Rootes' acquisition by the American Chrysler corporation.

George Singer began his bicycle-making business in Coventry in 1874. At the time, he was foreman of the Coventry Sewing Machine Company, from which he resigned. He was joined in the business by J. E. Stringer, his brother-in-law. It appears Singer was inspired to produce a bicycle safer than the Ordinary (penny-farthing) type standard at the time, by cyclist George Dominy. Singer did not alter the large front and small rear wheel design of the Ordinary, but by raking the front forks (a first) did make it safer. He patented the design on 24 October 1878.

He followed this with an 1879 model having a large rear wheel and small front wheels which could be folded aside. and in 1885 with a tricycle, rear wheels driven by chain, which also featured a handbrake (designed by Singer and his associate, R. H. Lea) on the rear axle.

In about 1888, Singer introduced the Rational, a diamond-framed model with wheels the same size, each about 30 in (76 cm) diameter. It also offered removable handlebars and removable rear wheel. While safer, its performance suffered. Nevertheless, it proved popular with cycle tourers.

In 1895, Singer Cycle faced a £600,000 "floatation by that egregious company promoter" Terah Hooley, but survived. It also weathered an industry slump in 1898 that wiped out many British bicycle makers.

Singer Cycle Company began producing motor cars in 1901.

Singer Cycle began motor vehicle production in 1901, purchasing the manufacturing rights to the Perks & Birch Motor Wheel, a one-cylinder engine contained in a spoked aluminium wheel, known as a motorwheel. It was a 222 cc (13.5 cu in) four-stroke designed by former Beeston employees Edwin Perks and Frank Birch. A unique feature was that the engine, fuel tank, carburettor and low-tension magneto were all housed in a two-sided cast alloy spoked wheel. It was probably the first motor bicycle to be provided with magneto ignition. It was perhaps the only motorcycle engine of its era with reliable ignition. These were fitted to bicycles. The design was used by Singer & Co in the rear wheel and then the front wheel of a trike.
