The map data is correct here.  The building footprint is tagged with information about the bicycle shop:

On the side of the building, there is a mural which is also tagged:

Different users of the map data decide what gets shown.  The default rendering of the map on osm.org shows both bike shops and artwork.  There is not always enough room on the map to show the icons and labels of all the features.  The more you zoom in, the more labels and icons are shown.

If you switch to the cycle map layer, you can see that bicycle shops are highlighted and appear are more prominently.
