I put my kid's 2000 GT Bullet on Craig's list the other day for $45 and it sold in a day. A fellow and his wife came over, she said she liked it, (by looks alone), he gave me $45 and they took off. It had a small frame on 24" wheels. They wanted something small for her to learn on and he said I might see it on Craig's list again in a month or two. You might try this. This way you not paying a lot for a bike that might not get used and you wife can determine on her own what she likes and dislikes about the bike's features. And if she get's into it she can look forward to shopping for that really cool bike that fit's just right!
