I truly appreciate your suggestions. Please keep 'em coming.
Sorry if I'm sounding dense here, but it occurs to me that there are several possible ways to hang bicycles. Is one way any better than the others? Hang by single wheel? (this would seem to be potentially unstable) Hang by two wheels? Hang by top bar of frame? (Sorry to be gender non-neutral, but I only have mens' models)
I'm still hoping that someone with a slick arrangement will post pictures.
