By popular demand, I have listed a value-packed sewing pattern on how to adapt most any bag to usage on a bicycle. In this pattern, you will find complete instruction plus crammed with photos & illustrations on how I selected, sewed, and attached an already sewn bag to all my bikes.
I know this project has taken me almost a year to complete. There were practically limitless combinations to at least look at and even attempt. I wanted to be as accurate and easy to do as possible.
