Bicycles *can* use hard shoulders, but this doesn't make the shoulder a
cycleway.  And shoulders that are open to bicycles and have been built or
rebuilt in the last decade or so will have gaps in the rumble strip
specifically to make it safer for bicycle traffic to get on or off the
shoulder safely.  There's usually 40-60 feet of rumble strip followed by a
10-15 foot long gap in a repeating pattern.  Pennsylvania has been
experimenting with buffered bike lanes, putting a rumble strip in the
buffer, but AFAICT, this is the only state that does this due to being the
only place with experimental approval to use a rumble strip on a bike lane.

But for just a generic hard shoulder on a freeway or highway?  cycleway=*
wouldn't apply at all.  Where signed as above where using the hard shoulder
is compulsory, then "no" would be a good value for all lanes in the
bicycle:lanes=* key along with bicycle=yes.
