TL;DR: The bicycle went from a pedal-less walking machine in 1817 to the recognizable safety bicycle of the 1890s in less than 80 years, driven by a sequence of specific mechanical inventions. In 1894, Philadelphia inventor John Carr patented a gearing system with elliptical wheels designed to reduce power loss during each pedal stroke. Original prints of that patent are available framed or unframed.
In the summer of 1817, German Baron Karl von Drais set out on a road between Mannheim and Schwetzingen on a wooden two-wheeled contraption he had built himself. He covered the 14-kilometer route in about an hour, faster than a horse-drawn postal coach on the same road. That run attracted enough attention in European newspapers to start a craze that, 80 years later, had produced one of the most transformative personal transportation devices in human history.
What makes the bicycle's development worth studying is how fast it moved. Most technologies evolve over centuries. The bicycle went from von Drais's walking machine to a practical, mass-produced transport vehicle within a single lifetime, driven by a concentrated sequence of specific mechanical problems that inventors solved one by one.
Karl von Drais and the Laufmaschine
Karl von Drais filed the first patent for his invention in 1818, calling it the Laufmaschine, German for "running machine." In France it became the draisine; in England it was called the hobby-horse or dandy horse. The design was simple and precise: two wheels aligned in a single plane, a steerable front fork, a padded seat, and a frame of wood. No pedals. The rider sat astride and pushed along the ground with alternating feet, then lifted their feet to glide.
The Laufmaschine was not fast by later standards, but it was faster than walking and required no horse. On smooth roads, an experienced rider could sustain speeds that surprised observers. Von Drais himself promoted it as a practical substitute for horse travel on good roads, particularly in periods when horse fodder was expensive or scarce.
The hobby-horse craze of 1818 and 1819 burned hot and brief. City authorities in several European cities and in New York eventually banned the machines from sidewalks after pedestrian collisions. The design had a fundamental limitation: without a mechanical drive, the rider's feet had to maintain contact with the ground, which restricted speed and wasted energy. The next step required a mechanical solution.
Macmillan's Pedals and the First Mechanically Propelled Bicycle
Credit for the first mechanically propelled bicycle is generally given to Kirkpatrick Macmillan, a Scottish blacksmith from Dumfriesshire. Around 1839, Macmillan built a bicycle with a rear-wheel drive system: treadles attached to the pedals connected via rods to cranks on the rear axle. The rider pushed the treadles forward and back in a rocking motion, which turned the rear wheel without requiring feet to touch the ground.
Macmillan rode his machine the 68 miles from Dumfries to Glasgow in 1842, a journey that took two days and reportedly ended with a minor collision and a fine for furious driving. He never patented the design or profited from it. A later Scottish blacksmith named Gavin Dalzell copied the design and sold versions of it, leading to some historical confusion about who actually invented the first pedal-driven bicycle.
The pedal and crank mechanism that became standard arrived in the early 1860s in France. Pierre Michaux and his son Ernest began attaching rotating cranks and pedals directly to the front axle of a modified hobby-horse frame, producing what became known as the velocipede or, in England, the "boneshaker." The name came from the ride: iron-tired wheels on cobblestone roads transmitted every vibration directly to the rider. Uncomfortable but popular. By the mid-1860s, Michaux was producing hundreds of velocipedes a year.
The Penny-Farthing: Speed at a Cost
The velocipede's front-wheel drive had a mechanical limitation. The bigger the front wheel, the farther the bicycle traveled per pedal revolution. Makers and riders quickly discovered that a larger front wheel meant higher top speed without requiring higher pedaling cadence. By the early 1870s, the high-wheel bicycle, called the penny-farthing in Britain for its resemblance to a large and small coin side by side, had arrived.
The penny-farthing's front wheel could reach five feet in diameter or more. An experienced rider could achieve speeds that made the bicycle genuinely fast transportation for the first time. The bicycle became a sport and a social phenomenon among young men with money and nerve, and competitive racing flourished in the 1870s and 1880s.
The problems were significant. With the rider seated directly above the front axle, a sudden stop, a pothole, or a loose stone could pitch the rider forward over the handlebars onto their head. There was no effective braking mechanism on early models. The height required to mount and dismount was considerable. And the cost of a quality high-wheel bicycle was substantial, keeping it out of reach for working-class riders.
The Safety Bicycle and Mass Adoption
The solution came in the 1880s. John Kemp Starley, a nephew of James Starley (one of the major figures in high-wheel bicycle manufacture), introduced the Rover Safety Bicycle in 1885. Its design was a fundamental departure: equal-sized wheels, a chain drive from pedals to rear wheel, and a low frame that placed the rider's center of gravity close to the ground. The Smithsonian Institution identifies Starley's Rover as the direct ancestor of the modern bicycle.
John Boyd Dunlop's 1888 invention of the pneumatic tire completed the safety bicycle's practical package. Inflated rubber tires absorbed road shock far better than iron or solid rubber, making long-distance cycling comfortable for the first time. The combination of the safety bicycle frame and pneumatic tires produced something genuinely new: a vehicle that almost anyone could ride, that was affordable enough to be mass-produced, and that was reliable enough to serve as everyday transportation.
The 1890s became the first great bicycle boom. Women's participation in cycling surged, facilitated by the safety bicycle's lower mounting height and more stable handling. Cycling clubs formed across Europe and North America. The bicycle contributed directly to arguments for better road surfaces, which would later serve the automobile. According to bicycle historians at the Cycling Embassy of Great Britain, the safety bicycle era of the 1890s democratized personal mobility in ways that had no precedent.
John Carr's 1894 Patent: The Elliptical Gear
With the basic bicycle form established by the early 1890s, inventors turned to refinement. One persistent problem was power loss during the pedal stroke. In standard circular gearing, the mechanical advantage varies depending on where the crank is in its rotation. At the top and bottom of the stroke, the rider's leg applies force roughly parallel to the crank arm, generating little torque. The power-producing portion of the stroke is actually quite short compared to the full rotation.
In 1894, John Carr of Philadelphia filed a patent for a gearing system using elliptical wheels designed to address this inefficiency. Carr's elliptical gear varied the effective gear ratio across the pedal stroke, providing a higher mechanical advantage during the phase when the rider's legs apply the most force and a lower ratio during the dead spots at top and bottom. The stated goal was to minimize loss of motion and power through the full rotation.
The engineering logic was sound. Elliptical chainrings have been reinvented and refined multiple times since, and non-circular chainrings appear on competitive bikes even today. Carr's 1894 patent represents an early systematic attempt to optimize the bicycle's drivetrain using the same analytical approach that was reshaping mechanical engineering across all industries in the late 19th century.
His design was part of a broader wave of bicycle patents filed in the 1890s, when the industry was growing fast enough to attract serious engineering attention. Frame geometry, braking systems, steering mechanisms, and drivetrain components were all subjects of active patent activity. Carr's contribution was specific and technical: a solution to a known efficiency problem in the bicycle's core mechanism.

Frequently Asked Questions
Who invented the bicycle?
The bicycle developed through contributions from multiple inventors. Karl von Drais built the first steerable two-wheeled vehicle in 1817. Kirkpatrick Macmillan is credited with adding mechanical propulsion around 1839. Pierre Michaux introduced rotating front-wheel pedals in the 1860s. John Kemp Starley's 1885 Rover Safety Bicycle established the basic form of the modern bicycle, with chain drive, equal wheels, and a low frame.
When was the penny-farthing invented?
The high-wheel bicycle, known in Britain as the penny-farthing, emerged in the early 1870s as manufacturers discovered that a larger front wheel allowed higher speeds without increasing pedaling cadence. The design dominated competitive cycling through the 1870s and 1880s before being displaced by the safety bicycle in 1885.
What is the safety bicycle?
The safety bicycle is the design that established the modern bicycle's basic form: two equal-sized wheels, a chain drive from the pedals to the rear wheel, and a low, diamond-shaped frame. John Kemp Starley's 1885 Rover Safety Bicycle is generally credited as the key design. The safety bicycle made cycling accessible to women, older adults, and anyone who found the dangerous high-wheel machines unapproachable.
What is John Carr's 1894 bicycle patent?
John Carr of Philadelphia patented a bicycle gearing system using elliptical wheels in 1894. The design varied the mechanical advantage across the pedal stroke, providing more torque during the phases where the rider applies the most force and reducing it during the less efficient top and bottom positions. The principle behind elliptical chainrings continues to appear in modern competitive cycling equipment.
Is a bicycle patent print a good gift for a cyclist?
It's a strong choice for anyone who rides seriously and cares about the sport's history. The 1894 Carr patent connects directly to engineering problems cyclists still discuss today, including drivetrain efficiency and gearing. Available framed or unframed from $49.99, it works in a home gym, a cycling room, or any space where the history of the bicycle belongs on the wall.
