Much later, when this type of bicycle was beginning to be replaced by a later design, it came to be referred to as the "ordinary bicycle". (While it was in common use no such distinguishing adjective was used, since there was then no other kind.) and was later nicknamed "penny-farthing" in England (a penny representing the front wheel, and a coin smaller in size and value, the farthing, representing the rear). They were fast, but unsafe. The rider was high up in the air and traveling at a great speed. If he hit a bad spot in the road he could easily be thrown over the front wheel and be seriously injured (two broken wrists were common, in attempts to break a fall) or even killed. "Taking a header" (also known as "coming a cropper"), was not at all uncommon.
