Quoted message said:In other words, this means that they can pass a law banning bicycles?
No, read the entire cite (which the original poster neglected to provide):
39002. (a) A city or county, which adopts a bicycle licensing ordinance or
resolution, may provide in the ordinance or resolution that no resident
shall operate any bicycle, as specified in the ordinance, on any street,
road, highway, or other public property within the jurisdiction of the city
or county, as the case may be, unless the bicycle is licensed in accordance
with this division.
