I recently reawakened to the joys of bicycle riding, and am in the market to purchase a bike. I live in NYC, and mostly want to ride the bike in Central Park and other well-beaten bike paths, and maybe eventually commuting to work if I feel brave enough. I don't want to invest too much yet, but I don't want a total piece of junk either. Would rather not go over $600. I'm mostly interested in the hybrid brands, and it seems like the major ones are Trek FX, Cannondale Quik, and maybe also the Jamus Allegra/Coda. I've tried out a Trek FX 7.2 that is on sale for $518, although there's only two left in stock. Any bicycle fans know anything about these brands or have any other recommendations? Grateful for your thoughts!!!
