I’m going to make a  bike rack out of wood to store the household's bikes on. It’ll need to hold 4-5 bikes.
What I’m looking for or have in my mind is a freestanding version that will hold the bikes at roughly a 45 degree angle. So front tire is in the air, back tire on the rack/ground. 
Hopefully that makes sense. The idea is to save a little floor space with the angle.  I don’t have any wall space to hang anything on.  So if I can work the angle and prop the bikes up that would help a little. 

If you’ve done this, I’d appreciate seeing pictures of what you made.

TIA,

Dave
