I'd love to see more pictures. Forgive my ignorance. What are drag bars? I don't like my seat either and I never plan on carrying passengers. I can barely hold the bike up myself. I'm only 5'4". Keep me posted on your modifications -the line of your bike is awesome. I think I might get a spare tank and fenders and paint them myself. Check out this YouTube video of this California surf -dude artist.
I love his style. I'd like to use the same materials except my design would be green and blue paisley. Like I said, a girl bike.
