Although Nevada state law does not prohibit biking on sidewalks, many local ordinances do: For instance, biking on sidewalks is illegal in Las Vegas on Fremont Street between Main Street and Seventh Street. Plus Las Vegas police may cite people for sidewalk-riding on the Strip (though there seems to be no Clark County ordinance prohibiting it). Always check local laws before taking a bike on the sidewalk. Also, cyclists should dismount before going over a pedestrian crosswalk.
