I've never been satisfied with the skinny tires. Even 38x700 still wasnt enough. Nice for just peddling, but add more weight and higher speed and your gunna destroy those rims. All my 27 and 700 rims are toast and iut of whack BAD. Hold out for a 7 speed cruiser. You'll be amazed how often you can find em cheap or free..
Also, I have soft spot for vintage road bikes and I say restore n ride or sell for 50!
