The rule
There is no statewide rule on sidewalk cycling — it is left to cities and counties in Kentucky. Kentucky has no statewide statute permitting or prohibiting sidewalk cycling. KRS 189.287 defines a bicycle as a vehicle and the regulatory framework lives in 601 KAR 14:020, but neither addresses sidewalks. Cities and counties set their own rules: Louisville prohibits sidewalk riding in business districts, Lexington restricts it in the central business district, and many smaller towns have no rule at all. See KRS 189.287 (Definition of bicycle).
Because Kentucky doesn't set a statewide rule, the answer is "it depends on the city." Central business districts, downtown cores, and school zones are the most commonly restricted areas. Always check the local municipal code before you ride on a sidewalk.
