When you look at many bike friendly European cites, you will notice that most people bike to work in normal street clothes. To do this, you need a classic bike with fenders and a chain guard. The Schwinn Coffee was perfect for this except I didn't have a way to carry my computer. Instead of choosing the bike basket in the front, I went with a wooden crate in the back. This is perfect for carrying my computer as well as groceries from the farmers market. Here is how I did it.
Step 1: Reinforce Box
I found this box at a Goodwill and was probably intented to be used for decoration because the slats were held on using small staples. The first thing I had to do was to reinforce the slats that were used for attaching to the bike rack. I did this by using some small L brackets and 1/4" X 20 screws.
Next I added a couple more nails to the other slats to keep them from falling off. The two slats that attach to the bike rack really take all of the load.
