I don't think most cities have so much elevation gain that biking to work isn't practical for most people. There are definitely exceptions, but I'm pretty sure a person of average fitness could bike to work without too much trouble in the vast majority of cases.
The majority of bikes sold have multiple gears, so hills should be even less of an issue.
