I've been wanting a cargo rack for my bike for awhile, but didn't have the cash to buy a manufactured one. Then my eye fell upon the beautiful pot rack I made a couple of years ago, and it occurred to me that some of that wire shelving might be just the thing I needed. There was some trial and error, but in the end, I put together a functional rack.
Step 1: Tools and Materials
My primary motivator here was "cheap". This cost me a grand total of $1.75 because I had to buy a bag of cable ties. Everything else I had in storage. Obviously, if you don't have what I have, you'd have to buy it.
1 Bicycle (mine is a GT Vantara I got from a Craigslist seller recently)
1 Wire Basket
2 Steel Shelf Supports
Allen wrench (4mm in my case)
Flashlight ('cause I did this at night)
