Just change the way to define the searchArea, (this is coming from the query wizard).

{{geocodeArea:Nederland}}->.searchArea;

and remove the timeout.
The whole query looks:

/*
This has been generated by the overpass-turbo wizard.
The original search was:
“amenity=bicycle_rental and name="OV-Fiets" in Nederland”
*/
[out:xml];/*fixed by auto repair*/
// fetch area “Nederland” to search in
{{geocodeArea:Nederland}}->.searchArea;
// gather results
(
  // query part for: “amenity=bicycle_rental and name="OV-Fiets"”
  node["amenity"="bicycle_rental"]["name"="OV-Fiets"](area.searchArea);
  way["amenity"="bicycle_rental"]["name"="OV-Fiets"](area.searchArea);
  relation["amenity"="bicycle_rental"]["name"="OV-Fiets"](area.searchArea);
);
// print results
out meta;/*fixed by auto repair*/
>;
out meta qt;/*fixed by auto repair*/
