If anything, a higher-density city should be more amenable to bicycles. Standard passenger cars are tremendously wasteful of physical space. You can fit half a dozen bikes in the road space that a car in the city requires (meaning, including following distance). Then there's the amount of space they take up when they're idle, and the extra space for them to maneuver past each other safely.
The mass of automobile usage has completely warped our civic spacetime in this country. I'm not saying there's anything wrong with cars per se -- they have important uses -- but they certainly don't help with density of all things.
