Step 3: Final Notes
The box works perfect for holding my laptop in a protective case and groceries. There are a couple of minor issues. First, since the box is so big, I need to swing my leg over the top tube rather than over the back tire. This takes a little stretching but you get used to it. I may cut the box down in the future to make this easier. Second the box puts a lot of weight high in the back of the bike. This causes the bike to be a little unstable. Third, there is a bit of a rattle. This is probably caused by the fact that the bike rack has a spring loaded mouse trap thing that is used to hold things down. In the future, I may change to a stronger bike rack. This should minimize the swinging and rattle.
Overall, the box adds a lot of functionality to the bike while still preserving the classic look. I am currently looking for a traditional dynamo light to complete the effect.
