Not looking forward to a long cold winter but thinking about my next project to keep me busy. I'd like to build a bicycle carrier that will lock onto the ADV rack preferably the exhaust side so I have the larger bag to carry riding gear and secure my helmet while peddling. Figure maybe I can find a trashed bag and buy the mounting hardware needed. Has anyone built such a rack? (Yep, I done the search) Any suggestions would be welcome.
