Persons shall be allowed to ride bicycles upon village sidewalks. Such bicycle riders will, in each instance, give the right-of-way to pedestrians and the speed of such bicycles shall not exceed such speed as is reasonable under the weather conditions, physical condition of the sidewalk and other bicycle and pedestrian traffic. Where necessary, a person riding a bicycle on a sidewalk may, because of one or more of the factors stated above, be required to dismount and walk the bicycle. A failure to grant the right-of-way to pedestrians or to ride in a manner or at a speed which is inconsistent with conditions shall be a violation of the provisions of this section.
