Hello all! My name is Karen. I'm 42 and for the last 6 months I've spent my time trying to improve my health. So far I've lost 44lbs and spend time exercising most days. After 6 months I finally feel in good enough shape to buy a bike.

I'm interested in riding for fitness and socialization. I have no interest in racing and my budget is fairly small. I have an opportunity to get this bike new http://www.diamondback.com/2012-air%C3%A9n-1 for $500 and wanted some opinions.

I understand this is just a very basic bike, but I figure I could learn how to road ride and if I love it I can upgrade in the future.
