in 1905. It was designed by Scottish engineer Alexander Craig and was a variant of a design he had done for Lea-Francis having a 2-cylinder engine. The Craig engine was replaced in 1906 by White & Poppe engines in Singer's two light car models. These were a twin and a 12/14 four-cylinder. These were joined by a White & Poppe-engined Doctor's Brougham and two Auster-powered tourers, a 12/14 and a 20/22. For 1907, the Lea-Francis design was dropped and a range of two-, three- and four-cylinder models was launched, using White and Poppe engines. The Aster engined models were dropped in 1909 and a new range of larger cars introduced. All cars were now White and Poppe powered. Singer experimented with a cyclecar, powered by a transversely-mounted aircooled engine in 1911–12. Instead, the company built a light car, the Ten, which debuted in 1912 with a four-cylinder engine; its main drawback was a three-speed transmission built into the rear axle. The Ten was the company's first big seller. The same year, two years after George Singer's death, the "bicycle wheel" radiator emblem was deleted. That year's primary product was a 16/20, powered by a White & Poppe engine. The use of their own power plants spread through the range until by the outbreak of the First World War all models except the low-volume 3.3-litre 20 hp were so equipped. The Ten's performance attracted interest from former racing cyclist Lionel Martin, who bought a copy right off Singer's stand at the 1912 Olympia Motor Show. Martin gave the car a thorough going-over, improving the engine's power and raising the top speed from . Martin set up shop in Henniker Mews, Kensington, England, tuning the four-cylinder cars, and did a robust business. This was aided by the motor racing success of Martin's own improved Ten, in particular at the Aston Clinton hillclimb. The Ten would also be sold by William Rootes, former Singer apprentice turned dealer. On 11 July 1914, Beatrice Blore drove a Singer Ten car up the cable track (with a gradient of 1 in 3 in places) of the Great Orme, in Llandudno, North Wales, becoming the first woman to drive up the steep and challenging headland. She was six months pregnant at the time and the drive was a publicity stunt developed by her partner George Wilkin Browne to help sell the cars at his Llandudno garage, North
