Anyone put a rear rack on their Katu? If so, please share what works. Would like to make mine a grocery workhorse so I need more cargo space than the front basket (which is great by the way). Would like a rack that is 20 inch wheel specific but that limits options so I'm open to racks for larger wheels. I tried transferring my Dahon rack over but the arms were way too short. There's quite a bit of real estate back there on the Katu.
