Hi. I would love advice for someone looking to ride for fitness. I am 5'1" 130lbs and live in Park Slope, Brooklyn. I'd like to ride in Prospect Park and on Ocean Ave down to Coney Island, all on asphalt bike paths. Based on online research, I'm looking at the Cannondale Quick 5, Specialized Vita, Trek 7.2 FX, Gary Fisher Wingra, Raleigh Cadent FT1 and the Giant FCR3 is a bit more pricey. All are around $500 which is my budget. Yelp and Citysearch have high ratings for Bay Ridge Bicycle World, but I don't think they carry all of these. So far, I've only been able to test ride the Specialized Vita. Any advice would be great.
