Most just need a tuneup and oil the chain. Some have dry rotted tires and maybe need new cables. As long as they're not rusted, all will work like new.
that's the bottom line.
I'm able to store only two bikes indoors, suspended in padded supports beneath the top tube. So, I choose the two that I'd like to preserve most. They come outside to be ridden only. The garage has outgassing from chemicals, lubricants, paints and the like. Also car exhaust as well as UV light. All of these are not great for bikes. Also, the garage
can be where incidental bumps, scratches and (gulp) falls can occur to one's bike.
