I have a Chimo. It is stock and yellow in color. I purchased it from a school rumage sale about 15 years ago. It looks like the blue one pictured. I know nothing about bikes. Would this be considered a quality bicycle? I'm thinking about starting to ride for exercise. I'm wondering if I should put any money into it or bring it to the Good Will. It has a rusty chain surface rust on some of the chrome and wheels in spots and it could probably use new cables and stuff. But it is in working order. It could definately use some new tires and tubes.
