The typical length of a bicycle, including the wheels, is around 68 inches. The length of a bicycle is determined by the size of the wheels and the wheelbase. The wheelbase of most bicycles is between 39 and 42 inches, and the diameter of most wheels is between 26 and 29 inches.
When sizing a bicycle, the wheelbase is not regarded to be significant. Instead, bicycles are sold according to frame size, which is the height of the seat tube. The inseam measurement, or the length of the rider’s leg, is an additional consideration to consider when purchasing a bicycle of the proper size. Consider the length of the top tube on the frame, which determines the distance between the seat and the handlebars.
