What is the minimum wheel diameter required for a vehicle to be classified as a bicycle?

The classification of a vehicle as a bicycle is determined based on specific criteria, including the minimum wheel diameter. For a vehicle to be officially classified as a bicycle in Utah, the minimum wheel diameter required is 14 inches. This standard helps ensure that the vehicle is practical for use, providing better stability, safety, and operational efficiency compared to those with smaller wheels. Vehicles with smaller wheel diameters often do not have the same handling characteristics or performance capabilities, which is why they do not qualify as bicycles under this regulation. This classification is crucial for defining the rules, regulations, and safety measures applicable to different types of vehicles on the road.
