One of the obstacles of commuting is making sure you are prepared and then getting out the door. Each year when I get my bike out and ride I have to park it way off to the side or behind things. 100% of the time it’s a pain. So … I buil a bike rack out of pvc pipe. I haven’t glued it yet, nor have I put any sand in the bottom pipe to add stability, but I think it will work just fine.
I based my design on someone else's and linked to it in the below post over in Clydesales & Athenas.
