Tim shows how to make milk crate bicycle saddlebags writes – “Not much to it. Just put a loop of rope through the top of the crates and set it over your mountain bike’s cargo rack. I drilled holes through the edge of my crates to get it to ride a bit lower, but that’s not really necessary. If you have an extra pass of rope at one end, you can hook it over the lip at one end of your bike rack so it won’t slide off. Enjoy!!” – Link.
