If your question is do I ride with a flag, the answer is yes. Always. Most trikes come with some kind of a flag mount on the trike. Sometimes it is built into the seat frame so the mount is always there and other times it is separate and attaches near the rear wheel. The OEM one that came with my Catrike 700 was cheesy plastic that soon broke so I made my own DIY two part flag mount. It attaches in two places so the flag never gets lost
