I have two road bikes I want to mount on a basement wall. I have the mounting hook, which is something along these lines. Two screws (and whatever variety of plug/anchor), and the hook holds the bike from the top wheel. The bikes weigh about 19 and 27 pounds.
Space is limited, and because of that I want to mount the hooks as close to a corner as possible, and as close together as possible (so there's enough room for the handlebars in between. The ideal distance from the corner to the first hook is 10", and about 19" from that (29" from the corner) to the next hook. I don't have a stud finder (I can pick one up tomorrow though), but if they're 16" apart, clearly this won't line up.
I'm looking for any common techniques for scenarios like this - I assume mounting to the drywall is out of the question with that load (I've confirmed the drywall by drilling in a couple places, there's also 4" of insulation behind the drywall between studs). I also want to avoid destroying the wall with more than 4 holes if possible, it's a rented apartment.
