You say there isn’t a bicycle cargo rack that can adjust to the exact size you need? Looks like you spoke too soon! Enter the Quirky Wingspan! This bike rack has extendable wings, so you can fly around town no matter what you’re taking with you. Plus, in addition to your wings, your parcels are secured with a removable bungee cord. And when you’re riding light, you’re still sitting pretty: The wings of Wingspan fold neatly in line with the seat. Wingspan has a quick release attachment for easy removal from your bicycle’s seat post for when you’re out racing.
