When the [[Great Depression]] began in 1929, Triumph sold its German subsidiary as a separate, independently owned company, which later merged with the Adler company to become [[Triumph-Adler]]. The Nuremberg company continued to manufacture motorcycles as [[Triumph (TWN)|TWN]] (Triumph Werke Nürnberg) until 1957. In 1932, Triumph sold another part of the company, its bicycle manufacturing facility to [[Raleigh Bicycle Company]]. By then, Triumph had been struggling financially, and Bettmann had been forced out of the job of chairman. He retired completely in 1933.

In 1936, the company's two components became separate companies. Triumph always struggled to make a profit from cars, and after becoming bankrupt in 1939 was acquired by the [[Standard Motor Company]]. The motorcycle operations fared better, having been acquired in 1936 by [[Jack Sangster]], who also owned the rival [[Ariel (vehicle)|Ariel]] motorcycle company. That same year, the company began its first exports to the United States, which quickly grew into the company's single most important market. Sangster formed the '''Triumph Engineering Co Ltd.''' largely directed by ex-Ariel employees, including [[Edward Turner (motorcycle designer)|Edward Turner]] who designed the 500&nbsp;cc 5T [[Triumph Speed Twin]]—released in September 1937, and the basis for all Triumph twins until the 1980s.{{Citation needed|date=May 2013}} Contrary to popular belief, however, this was not Triumph's first parallel twin. The first was the [[Val Page]] designed model 6/1, introduced in 1933. This first twin performed well as a racer but was ultimately unpopular with the public and did not sell well.<ref name="Davis Triumph 6/1">{{cite journal|last=Davis|first=Simon|title=Triumph's First Twin: Triumph 6/1|journal=Motorcycle Classics|date=May–June 2013|url=http://www.motorcycleclassics.com/classic-british-motorcycles/triumph-6-1-zm0z13mjzbea.aspx|access-date=9 May 2013}}</ref> After Turner arrived, with his usual brusque manner, the 6/1 ended, later to be replaced with Turner's design. The 6/1 engine tooling was also scrapped. In 1939, the 500&nbsp;cc [[Triumph Tiger 100|Tiger T100]], capable of {{convert|100|mph|km/h}}, was released, and then the war began.
