Cut a piece of plywood to the same footprint as a insulated pizza delivery bag. Drill strategic holes into the plywood to allow you to secure the plywood to your rear rack using zipties, hose clamps, etc. Mount the insulated pizza bag to the piece of plywood using double-sided velcro.
You can't walk by a pizzeria in NYC without seeing 3-4 of these with precisely the setup dug describes. Not as pretty as the Cetma rack (which are very nice), but much less expensive.
Yeah, lots of NYC delivery people use the Wald basket. But cheap, quick and easy (and also flexible for other uses) might be:
- cheapest front platform rack you can find (you can also probably mod a cheap rear platform rack with enough hose clamps and creativity). Nashbar front rack, Pletscher, Wald, you can find something for $10-30, even brand spankin' new.
- you have an oven, right? Do you really use all of the racks inside it? No? Then take one out, and clean it off. Free-ish.
- Zip ties and/or used inner tubes. Or more hose clamps, if that's your thing. To strap the oven rack onto your platform rack. Make sure it's stable! And flat! Almost free.
- bungee net and/or bungee cords and/or whatever other straps you might want to use. Free (if you have them already), maybe $10 for a net at a bike shop.
I haven't done this before, but have seen it, and thought about it myself. Not to carry pizza, but copious amounts of sparkling water. And if you are not long for the world of pizza delivery via bicycle, you can always put your oven rack back into the oven, and use your front rack for other important things, like carrying six packs of beer to the lake.
Not sure how your corporate overlords at Papa John's might react to you delivering without a car, so I'd also look into getting a job at Jimmy John's, Potbelly's, or another sandwich place that does deliveries by bike. A lot easier to carry a 6" sub sandwich than a pizza, I think.
Thanks guys this gives me some ideas. Ill let you know how things work out.
