16tums
16tums is a term that can refer to several different things, primarily related to the measurement of an object's diameter in inches. In the context of bicycles, "16 tums" or "16-inch wheels" commonly describes the size of the wheel, often found on children's bikes or smaller folding bikes. This measurement is a standard in the bicycle industry for specifying wheel diameter.
Beyond bicycles, "16tums" might appear in discussions about other objects where a 16-inch diameter is relevant.
