All of these modalities were addressed in Swift v. City of Topeka, 43 Kan 671, 23 P 1075, 8 LRA 772 (Kan 1890). The ruling was "Each citizen has the absolute right to choose for himself the mode of conveyance he desires, whether it be by wagon or carriage, by horse, motor or electric car, or by bicycle, or astride of a horse, subject to the sole condition that he will observe all those requirements that are known as the ‘law of the road.". The case further established that "It may be said of bicycles with greater force, as was said of the first use by railroads of public streets, that they are not an obstruction to, or an unreasonable use of, the public streets of a city, but rather a new and improved method of using the same, and germane to their principal object as a passageway. ..."

This is but one of many, many court cases involving bicycles, or other self-powered modes of transportation on public roads. The precedent has been well established, even if it is not vigorously enforced.
