First bike: burnt orange, heavy Sears kids bike. I was in first grade and we had just moved back to Pittsburgh from New York. I put a lot of miles on that baby. The neighborhood where we lives was very hilly, so I learned to master climbs quickly. Had an awful downhill wipe out on that bike---cost me my thumbnail and I still have a scar on my left thumb from it.
Second bike: my sister's purple banana bike. It had a sissy bar, white basket with daisies, etc. Spent a lot of summer days cruising on it.
When I was 13 or so, my dad bought me and my little brother "English Racing Bikes." They were 70s rust/orange in color, steel frames, relatively expensive 10 speeds. We rode them for hours, exploring.
Lost interest in cycling when I started working at age 16 and didn't start riding again until a few years ago when me and my hubby bought Trek 7300s. Since then:
Terry Classic (am going to sell this one)
Terry Limited edition Fast Woman which is permanently on my trainer (reach is a bit too far for me--I need to replace the stem)
Specialized Dolce Elite (beater bike #1)
Specialized Dolce Comp (beater bike #2)
Pink Luna Eclipse
Bianchi Eros Donna
Pink/Purple Luna Orbit (currently being built--should have in 6-8 weeks)
