I tried buying fenders for my bike. None of them fit. So I found these instructions to make my own custom fenders. I was able to find a big coroplast sign to recycle. (This has also been called gator board. It’s constructed like cardboard except it’s plastic.) I cut two strips each 2 inches wide and 8 strips 1 inch wide. Take a look below to see how it’s constructed.
The nice thing about making your own fenders is that you can make adjustments really easily. Something is rubbing or too long? Cut it and fix! Want a different color? Spray paint! Super super easy. Now if it would only rain for me to see how well they work.
