What are the unique features and characteristics of an old-fashioned bicycle with a big front wheel?

An old-fashioned bicycle with a big front wheel, also known as a penny-farthing, is characterized by its large front wheel and smaller rear wheel. This design gives it a distinctive appearance and a high seating position for the rider. The penny-farthing lacks modern features such as gears and brakes, making it more challenging to ride and requiring skill and balance from the rider. Despite its outdated design, the penny-farthing remains a symbol of vintage cycling history.
