Though the ladies' version of the roadster largely fell out of fashion in England and many other Western nations as the 20th century progressed, it continuously remained popular in the Netherlands right to the present day. The "Omafiets" as it is known, is a national icon, and is even used by men in the Netherlands; this is why some people refer to bicycles of this design as "Dutch bikes". In the Dutch language the name of these bicycles is "Omafiets" ("grandma bike") a term which has been in use since the 1970s. However, in Frisia they often call them "Widdofyts" (West Frisian for "widow's bike"). The classic "Omafiets" is still in production in the Netherlands and has changed little since 1911: it comes with a single-speed gear, 28 x 1½ (ISO 635) wheels, black painted frame and mudguards (with white-blazoning at the back of the rear one), and a rear skirt guard. Modern variants, be they painted in other colours, with aluminium frames, drum-brakes or multiple gear ratios in a hub gearing system, will all conform to the same basic look and dimensions as the classic "Omafiets". The Dutch gentlemen's equivalent is called the "Opafiets" (Dutch for "grandpa bike") or "Stadsfiets" ("city bike") and generally has the same characteristics but with a "diamond" or "gents'" frame, thereby much the same as the gentleman's roadster in England and elsewhere.
