Mini Cargo Rack

I've used many cargo racks. Most are bigger and stronger than I need.
I decided to build one from some parts left over from a shelving unit.
My fender struts are very strong, so I can support my mini rack on them.

First pic - Mini rack is folded and stowed.

2nd pic - Cross brace is unfolded for stability.

3rd pic - Rack trunk is attached to the mini rack and ready for cargo.
I tested this setup with six cans of soup on board with no problems.

Bits - My original plan was to have a second brace on the rear. Clearance problems between the bolts and fender deterred me. A second brace would have also made the rack longer when the brace is folded or stowed.
To compromise, I did two things. First was to put a license plate in the bottom of the rack bag for strength (it fit great with some folding on the ends).
The second compromise was to fasten some zip ties at the rear of the rack to provide a place to fasten the rear of the rack bag.
So far, it has proved adequate for hauling a gallon of milk or libation.

While I was working on the mini rack, I added some springers to my seat. The springs came from my son's old push scooter.

The springers are just for looks. They do not support the seat. I had made a cantilevered layback mount for the seat (again, from parts from a push scooter).
The home made cargo rack can sway a bit. As long as I don't overload it (10 lbs max), it will keep things in place.
