This is a Terry Symmetry Woman's (or small person) bicycle. This is my wife's bike and hasn't been ridden in years. I'd be guessing how old it is------ I don't know. She's the 2nd owner and I'd be guessing how much it cost new---maybe $700 ????? She wants $200 out of it and you'll have to pick it up in Mt. Vernon, Illinois. It's in perfect garage kept condition with almost new tires. My wife has had several strokes and just doesn't have the balance to ride this bike anymore. We've kept it around but have realized she'll never be able to ride it again. She's bought a very small mountain bike that she still can ride--just easier to handle. I do not know the frame size--or even how to measure a frame ??? My wife is 4'9" tall----from looking at how low the seat is in the seat tube I'm betting a taller rider could ride this-------don't have any idea of how tall tho. The bike looks like a full size road bike except for the smaller front wheel. It has seven gears in the rear and 3 in the front for a total of 21 speeds. Shifts perfectly Sold-------------well not really. Found a nice young girl who's parents couldn't afford to buy her a bicycle and I gave it to her for X-mas. Just did my heart good to do something nice for somebody at X-mas.
