A glance at the history shows a lot of yoyo tagging on this about whether it is a footway or a cyclepath. Cycleway with bicycle=no seems to be the result (intended or accidental?). But Regents Canal doesn't seem to be *formally* designated as a cycleway. Personal opinion (not necessarily OSM's) is that l is more of a footway with bicycle=permissive than a cycleway. But certainly a cycleway with bicycle=no is useless nonsense,
