Greetings all. This is my first post and hopefully many more to follow. I'm interested in getting a single speed/fixed gear bike and was wondering if anyone can point me in the right direction. From doing some research I realize my requirements are straight forward and simple. 1) Single speed 2) Weight "Not trying to lug a tank" 3) Flat bar or raised bar and 4) Price range equal to or less than $550. My riding skills are very limited, so I am generally looking for a bike where I can hop on and just ride. This bike will be used for casual riding around town and maybe something to use within a 10 mile radius. Will any of these bikes meet my requirements?

Also, can I find what I am looking for given my price range?
