200 years from a wooden running machine to the e-bike.
The bicycle came late. It needed no new science, only a good idea: that you can balance on two wheels in a line if you keep moving. A German forester proved it in 1817 by running on a wooden frame. Pedals, huge front wheels, chains, air-filled tyres and gears followed in a rush, and the bicycle went on to free women, build aeroplanes, fill the streets of China and win back the cities of today.
No pedals yet. Riders sit on a frame between two wheels and push along the ground with their feet.

The running machine
Karl DraisMannheim, Germany
Drais rode his Laufmaschine, a wooden frame with two in-line wheels and a steerable front, from Mannheim to a coaching inn and back, about 13 km in a little over an hour: faster than walking. Some historians link the invention to the “Year Without a Summer” of 1816, when failed harvests made horses costly to feed, but the link is debated.
Why it mattered. It proved that you can balance on two wheels in a line as long as you keep moving and can steer.
London coachmaker Denis Johnson built an improved version, the “pedestrian curricle”. Fashionable young men rode “hobby horses” or “dandy horses” until the fad faded, partly because riders on pavements annoyed pedestrians.
Why it mattered. The first bike boom, and the first complaints about cyclists.
Macmillan, a blacksmith, is said to have built a two-wheeler driven by treadles and rods to the rear wheel. The evidence is thin and historians still argue about it.
Why it mattered. A reminder that ‘who was first’ is often uncertain.
Pedals go straight onto the front wheel, and the wheel grows huge to go faster.

Pedals on the front wheel
Pierre Michaux, Pierre Lallement and othersParis, France
French makers fitted cranks and pedals straight onto the front wheel. The Michaux company began producing these velocipedes in quantity in the late 1860s. On cobbled streets their iron tyres earned them the nickname “boneshakers”.
Why it mattered. For the first time, a rider could keep their feet off the ground.
A 1,200 m race in the park of Saint-Cloud is often cited as the first recorded bicycle race. It was won by James Moore, an English rider living in France.
Why it mattered. Racing drove bicycle design from the start.
Meyer built wheels whose thin wire spokes were pulled tight, instead of heavy wooden spokes that push. The rim is held in shape by tension from every side.
Why it mattered. Light, strong wheels made bigger, faster bicycles possible, and every spoked wheel since works this way.
James Starley and William Hillman (Ariel)Coventry, England
With the pedals fixed to the front wheel, the only way to go further per pedal turn was a bigger wheel. Front wheels grew to 1.5 m across. Later nicknamed “penny-farthings”, they were fast but dangerous: a bump could pitch the rider headfirst over the bars.
Why it mattered. A giant wheel was a gear ratio you could see. Chains would soon do the same job safely.
Swiss-born engineer Hans Renold invented the bush roller chain, whose rollers turn on bushes to cut friction and wear. It became the chain used on almost every bicycle.
Why it mattered. A reliable chain made it possible to drive the rear wheel and choose any gear ratio.
A chain to the rear wheel, air-filled tyres and equal-sized wheels: the shape we still ride, and a craze that changed society.
1885
The safety bicycle
John Kemp Starley (Rover)Coventry, England
Starley's Rover had two wheels of similar size, a chain driving the rear wheel, and a steerable front with the rider sitting between the wheels. Gearing replaced the giant wheel, so it was fast and much safer.
Why it mattered. It's the basic shape of almost every bicycle since.
Dunlop, a vet, made air-filled tyres for his son's tricycle to smooth out bumpy roads, and patented them. Robert William Thomson had patented a pneumatic tyre in the 1840s, but it hadn't caught on.
Why it mattered. Comfort and speed together. Pneumatic tyres went on to every car.
Annie LondonderryBoston, USA, and around the world
Annie Cohen Kopchovsky, riding as “Annie Londonderry”, set off from Boston and returned about fifteen months later, having travelled around the world by bicycle and steamship.
Why it mattered. Widely called the first woman to cycle around the world, at a time when women riding at all was controversial.
In an interview with the journalist Nellie Bly, the suffragist Susan B. Anthony said she thought the bicycle had done more to emancipate women than anything else in the world. Bicycles gave women independent travel and helped change clothing and ideas about what women could do.
Why it mattered. The bicycle was a social machine as much as a mechanical one.
A freewheel lets the rear wheel keep turning while the pedals stay still, so riders can coast. Coaster brakes, worked by pedalling backwards, followed.
Why it mattered. You no longer had to pedal every second the wheels turned.
Wilbur and Orville WrightKitty Hawk, North Carolina, USA
The Wright brothers ran a bicycle shop in Dayton, Ohio. They used its tools, its chain drives and their understanding of balance and control to build the first successful powered aeroplane.
Why it mattered. Balancing a bike taught them that a pilot must actively control an aircraft, not just keep it steady.
Derailleurs, quick-release wheels, mass production in China, and new kinds of bike for mountains.
1930
The quick-release wheel
Tullio CampagnoloVicenza, Italy
Racer Tullio Campagnolo, the story goes, lost time in a race struggling to undo frozen wing nuts with cold hands. He invented a lever that frees a wheel in seconds.
Why it mattered. Quick changes of wheels and tyres became normal.
Earlier derailleurs existed, but Campagnolo's Gran Sport used a parallelogram that moved the chain cleanly between cogs, setting the pattern for the derailleurs on most bikes today.
Why it mattered. Many gears, shifted while riding.
Tianjin Flying Pigeon Bicycle FactoryTianjin, China
The heavy, black Flying Pigeon PA-02 became a symbol of modern China. Tens of millions were made, and for decades the streets of Chinese cities were rivers of bicycles.
Why it mattered. Often called the most widely used vehicle in history.
Joe Breeze, with Gary Fisher, Charles Kelly and othersMarin County, California, USA
Riders racing old bikes down Mount Tamalpais wanted something tougher. Joe Breeze built the Breezer, one of the first purpose-built mountain bikes, with wide tyres, strong brakes and many gears.
Why it mattered. A new kind of cycling, and bikes that go almost anywhere.
Kooijman, Meijaard, Papadopoulos, Ruina and SchwabDelft, Netherlands, and Ithaca, USA
Writing in Science, the team built a strange bicycle with no gyroscopic effect and no trail, and showed it could still balance itself. What matters is how the bike's mass is arranged, so the front steers into a lean.
Why it mattered. After nearly 200 years, it overturned two popular explanations of why bikes stay up.
