I recently got back into bicycling after a looooooong hiatus. The last bicycle I seriously put mileage on was my old Schwinn Traveler when I was in H.S., and I'm 33 now.
Last fall I picked up a Univega 12 speed roadbike at the thrift store in nearly perfect condition for $20.00, and started bicycling back and forth to school twice a week - about 35 miles a week, plus weekend pleasure rides.
I've begun restoring older bikes to working condition as a hobby. My girlfriend currently has an early '80's-era Schwinn 10 ladies roadbike that I fixed up for her, and a mid-'70's ladies 5 speed comfort bike from JC Penney that was literally a non-rolling wreck when I got it for $1.50. the Schwinn she rides at work back and forth between the train station and work, and the comfort bike is her at-home bike.
Currently I'm restoring an old cruiser bike of ABSOLUTELY indeterminate origin to excellent working and cosmetic condition for a friend of mine. As near as the people that I know can determine, it's possibly a custom built frame, or a very small manufacturer, and it dates from sometime in the late '40's to the early 50's. In partial trade for the work, he gave me a 1960 ladies Royce Union 3 speed which will be my next project for my GF.
