From the Lawrence Daily Journal-World for Sept. 18, 1973:

The Journal-World today began a series of articles analyzing some of the issues facing cyclists and motorists in the city. Today’s article began by stressing that curb cuts on city streets were for the benefit of persons using wheelchairs, not for bicyclists. Lawrence Police Chief Richard Stanwix pointed out that local ordinances prohibited the riding of bicycles on sidewalks in business districts and on the Kansas University campus due to the increased danger to pedestrians. “A lack of understanding on the part of bicyclists that they must obey traffic regulations” was the major problem leading to bike accidents, according to KU Security Division Director Mike Thomas. State laws and city ordinances both specified that bicyclists must obey the same traffic regulations as drivers of motorized vehicles, including passing another bicycle rider on the left, not on the right; yielding to pedestrians; and obeying speed, traffic, and stop signs. A Lawrence ordinance further restricted bicyclists to riding in single file, and only one person could legally ride on a bike unless it was specifically designed for two persons. (Stanwix and Thomas agreed that a bicyclist carrying a baby securely fastened in a backpack was probably operating within the law, but a youngster was riding on the handlebars or the luggage rack was riding illegally.) A 25-cent yearly license was required for all Lawrence bike riders; persons failing to buy one or to have their ride properly equipped were subject to a fine of $25. Proper equipment included working brakes, a white light on the front and a red light or reflector on the back if ridden at night, and, for bikes purchased after Jan. 1, 1974, reflectors on the pedals. Police Chief Stanwix noted that the three-wheel bicycles recently on the market were subject to the same laws and ordinances as the two-wheelers.
