Paris. There are some promotional videos up on youtube if you want to see what riding past the Eiffel Tower on a beach cruiser looks like. I'm the guy at 1:12 in the first video if you search "Bike Tour Paris". I have to say that the French know how to do bike lanes. They're EVERYWHERE and where they ain't there are wide sidewalks if you're scared of traffic and all the big streets have an entire lane dedicated to buses and bikes.
