hi shanewh, I can see you're brand new to OSM, I suggest reading some wiki pages like https://wiki.openstreetmap.org/wiki/Good_practice

In this case, it's easy, just tag the bike lane width per https://wiki.openstreetmap.org/wiki/Key:cycleway#Supplementary_details then data consumers like maps and routers can factor that in. You can even then make your own map style using OSM data that ignores bike lanes less than a width you choose, then others can make other map styles showing bike lanes even if they might be narrow.
