"Footpaths" are paved pedestrian ways (they might allow cycling but are primarily for walking). You can use a wheelchair on them (usually).

"Cyclepaths" are cycling roads that your grandmother would be able to ride on. (They might allow walking but are intended for cycling).

Hiking trails are "paths" (not "foot paths").

MTB paths are "paths" (not "cyclepaths").

Paths where cycling is allowed should be tagged "bicycling=yes". Ways where cycling isn't allowed should be tagged "bicycling=no".

Roads are assumed to allow cycling (which means they don't need to be tagged "bicycling=yes").
