I found in my garage a bottle of lube for bike chains and I was thinking that it might work in my bearings. I wanted to know if anyone knows whether this is a bad idea or advice?

I don’t know if you mean in Oust bearings specifically, or bearings in general.
Generally, the bike chain lube would be good, as long as you are talking about oil rather than grease. Make sure to use no more than one drop of oil per bearing or else the excess will just leak.
