I've been wanting to buy a bike ever since I moved into my current apartment, and after two years of lollygagging and a lot of fat 'round my belly I'd say it's about time I picked one up. I used to own a nice BMX - think it was BMX, anyway; certainly was small enough - but it has long since fallen apart, and I'd like something larger anyway. I'm also not sure I need something quite so trick-centric for urban riding, and urban riding is the only thing available to me. What kind of bike would you lot recommend? A $300 to $500 price range is preferable.
