I'm looking to use my bicycle to run errands as well as for commuting, and I'm thinking of means of increasing the carrying capacity. At the moment I have a rear rack, to which I attach my bag for university with a bungee.
I do have an old wooden schweppes lemonade crate which I think would look pretty good on the bike and should be sturdy enough. What are my options for installing the crate to the rack? I know I could just bolt it in place, but I'd like to be able to remove it when not using it.
