These lined bags have zippers in the bottom. The bags were designed for the bar that extends from the handle bar to the seat, but could be used over the handle bars instead.
This project is sewn, however I am certain a crafter who has had experience using rubber glue could whip this out in a hurry. I know it would have been easier than sewing it. I am sure Velcro would be a great option instead of a zipper, however I believe it would have to be glued. It is not necessary to paint or line them.
I have a friend who depends on his bike to go everywhere. I decided to make him a couple of bags for his bike. This is what I came up with, using supplies I already had on hand.
Step 1: Supplies For This Project
This project is simple enough for any crafter to make. The difficult part for me was sewing it together because my machine is not suitable for heavier fabrics. In the beginning I had planned on making these bags with Velcro. I experimented trying a rubber glue and it did not hold so I decided to put in a zipper.
A large truck inner tube 16x 24 cut 4 (I got my inner tubes at the dump. )
Lining 16x24 cut 4
2 9 inch Zippers or Velcro (would be easier if you know of a good rubber glue)
Vinyl and fabric paint Dupli-color has worked the best (since I have posted this.) Krylon was ok but if there is stress on the rubber it may crack as I have read. That is why I came back and edited this part.
