I`ve got an old Gary Fisher mountain bike that I rarely ride anymore because I haven`t been to the woods to ride it lately. A Cannondale Synapse that I take to the beach to push myself, it makes me want to go fast for some reason and finnally a Cannondale Quick CX4 that I just purchased for riding around the house and just having fun. I have never had this many bikes, I`m living in bike heaven, but it only took me 56 years to get here.Tell us which one you get when you get it. As for a lock I just have a cheap walmart lock right now that is pretty light weight, thinking about getting a better one
