Can I please ask a question purely related to @bikerouter here? It sounds basic, but there are often things I don't understand on the map.

On this screenshot for example, I am about to select the route, coming from the north (in the Durance valley, France), forcing it to follow the veloroute V64/V862, heading south. All well.

But what is the "2" on the more direct route, coloured in magenta, supposed to indicate? Is this also a bicycle route, and if so, which one?
To me, it is often a problem on these maps that I cannot find a proper legend that tells me what the colours and numbers indicate.

Thanks for any help (in English, German or French, it does not matter).

This is a marked cycling route. Looking at this place in more detail on https://cycling.waymarkedtrails.org/#route?id=10163060&type=relation&map=11.0/44.0778/6.146 its Tour de Fontbelle.

I suppose that this route is marked with a "2".

@Einzigartiger @wolfgangcramer @bikerouter Yes, it's definitely too hard to get this kind of information on some maps. On OSM one can click on "Query features".

I also find Facilmaps sometimes helpful to see differences between differently rendered maps.

This is "unfortunately" a problem of OSM. Its Database contains so much information that it is hard to decide what could be relevant in special use cases.

Bikerouter offers the ability to jump to the current location in OSM using the links at the bottom right. There you can again use the "query feature" button. If the cycling routes are visible in Bikerouter there is also the link to waymarkedtrails which is the source of those routes.
