(a) It shall be unlawful to park any bicycle along buildings in such manner as to interfere with pedestrians, or along roadways where they may interfere with traffic or with persons getting into or out of motor vehicles. No person other than the owner or operator shall move, or in any manner, interfere with any bicycle properly parked, nor shall any person interfere or, in any manner, hinder any person from properly parking a bicycle, except that members of the Police Department and Fire Department may move, or, in proper cases, prevent the parking of the bicycle, when, in the judgment of the policeman or fireman, his action is necessary in order to properly safeguard persons or property.
(b) The Chief of Police will cause bicycle parking racks to be installed at places to be determined by him within the central business district. No bicycle shall be parked within one hundred feet (100') of such bicycle parking racks except in said racks. (M.C. 1963, § 20.715, Ch. 20A)
