Donna,
PM sent.
I just finished overhauling a 19" step-thru fame Schwinn Mirada. It would be a perfect rough street/commute bike. Sugino triple crank, 5 gears in the back (32 or 34t low gear - need to count
) for hills. Full fenders, new tires/tubes, rack mounts (I might even have a rack that fits), upright bars, thumb shifters, Shimano Light Action dérailleurs, and cantilever brakes.
All cleaned, overhauled, tuned up, and completely ready to ride. I'm in San Ramon, not too far away. PM if you're interested - I just took photo's of it, and am ready to list in on CL.
