He was the first president of the Tricycle Association from 1944–1950. He worked as a journalist, editor of Cycling magazine for nine years. In 1920, he took over as president of the Cyclists Touring Club[2] at a time when membership had dwindled to 8,500. By the time he retired in 1945, membership had exceeded 50,000.
The Bicycle wrote: "The new broom, if it went to work in unspectacular fashion, swept exceedingly clean. The five-shilling [25p] subscription was doubled, and although many heads were shaken at the 'folly' of such policy, its success was never in doubt, and membership figures ascended into the fifteen, twenty, twenty-five, and thirty thousand classes."[3]
He became president of the Road Records Association after 34 years on its executive committee. He was an opponent of the revival of massed racing on the road when it was proposed by the British League of Racing Cyclists. His fear, and that of the National Cyclists' Union, was that asking the police for permission to hold a race ended the freedom of cyclists to hold races, or at any rate lone races against the clock, without interference. Under the headline A hopeless revolt, he wrote in Cycling:
- They have plunged into their dangerous experiment without regard for the consequences... I understand that the 'rebels' want to go on holding races by police permit and under police protection; and when this is withdrawn they are apparently content to put up the shutters and go out of business as promoters.... If we voluntarily place road-racing under police control, we sign its death warrant.... If we are to race on the road, for heaven's sake let us do it as free citizens, and not by permission of the police.
The cycling importer and wholesaler, Ron Kitching, said of him: "He was a very proper gentleman; he never said a wrong word or got overheated."[4] Stancer was awarded the Bidlake Memorial Prize,[5] one of British cycling's top honours, in 1943.
