Safety bicycle

A safety bicycle (or simply a safety) is a type of bicycle that became very popular in the late 1880s as an alternative to the penny-farthing (also known as an "ordinary" or "high wheeler") and is now the most common type of bicycle. Early bicycles of this style were known as safety bicycles, because they were safer than the high wheelers they were replacing. Even though modern bicycles use a similar design, the term is rarely used today and is considered obsolete outside circles familiar with high wheelers.
