The Penny-Farthing’s Wheel Was Its Gear
Before a chain could multiply the force of a rider’s legs, a bicycle’s pedals could simply turn the front wheel itself. That made wheel size a built-in gear ratio: one rotation of the pedals produced one rotation of the wheel. A larger wheel therefore carried the rider farther with each turn, allowing a strong, fast rider to travel at a useful pace without a complicated drivetrain.
The design also had a practical advantage on rough roads. A large wheel was less likely than a small one to drop sharply into ruts or bump over stones, making the ride feel smoother. But that benefit came with a steep price: the rider sat high above the ground, and the front wheel had to handle both steering and propulsion.
Speed Came With a Difficult Mount
Getting onto the bicycle required more than swinging a leg over a low frame. Riders typically used a small step behind the front wheel, pushed off, and climbed into the saddle while the bicycle was moving. The rider also had to balance above the wheel and manage the pedals closely: because they were attached directly to it, the feet kept moving whenever the wheel turned.
A sudden stop or a wheel catching on an obstacle could pitch the rider forward. The penny-farthing was thus a machine that rewarded skill and speed but made ordinary mistakes consequential. Its height was not just a dramatic style choice; it followed from the most direct way then available to make each pedal stroke cover more ground.
The Tradeoff That Made Room for a New Design
The later safety bicycle separated wheel size from distance traveled. A chain could drive a rear wheel through gears, so designers no longer needed an enormous front wheel to give riders a long stride per pedal turn. With smaller wheels and a lower seat, mounting and stopping became less perilous.
The penny-farthing’s towering shape was therefore a solution to a specific mechanical limitation—and its vulnerability was a reminder that a faster machine is not necessarily an easier one to ride.
