Not sure if this would work for you here is what I have rigged up for my lunch cooler. It could act as a small "basket" I suppose. I took some monofilament fishing line and sewed the strap on the cooler so the length would let the cooler ride at the desired height when the strap was looped behind the bolts on the stem. My finger is on the excess part of the strap behind the stitching. It is draped over the bars and held tight to the stem with a short piece of velcro. Easy on easy off.
