NEWER AND BETTER: I improved the box-mounting tabs on my cargo bikes. It's a minor modification, but a pretty significant benefit. These tabs used to be a single hole which didn't allow for any wiggle room. New tabs now have a curved slot which allows the bracket to move slightly up or down, forward or back. This is great for fine-tuning the box orientation/angles AND gives customers greater flexibility if they want to make their own box and use my pre-made brackets.
