I think they can be described as covered stands, and the wiki entry for”shed”suggests the same : https://wiki.openstreetmap.org/wiki/Key:bicycle_parking

Just noticed these ones in Leith tagged as a bicycle_parking=streetpod, which might be the best option actually : https://www.openstreetmap.org/node/10975467915. Only 268 instances of that tag in TagInfo for now, but if we’re going to retag them that option gets my vote 👍
