Looking for a woman's hybrid bike for a coworker of my girlfriend. She is in her 50s and about 5'4". She went and looked at a Trek Verve but it's way out of her price range. I found a Diamondback Vital 2 online and it seems to get decent reviews. She would like to stay between $300 and $400. Is this a decent bike? Any other bikes to look at? We have a Trek and Specialized dealers in our area but that's it besides the big box store type places.
