Cycle Picture Collection from Image Kingdom








  A modern bicycle by definition is a rider-powered vehicle with two wheels in tandem, powered by the rider turning pedals that are connected to the rear wheel by a chain, and having handlebars for steering and a saddle like seat for the  rider. With that definition in mind, let's look at the history of early bicycles that led up to the modern bicycle. A few years ago, most historians felt that Pierre and Ernest Mich aux, the French father and son team of carriage-makers, invented the  first bicycle during the 1860s. Historians now disagree since there is evidence that the bicycle and bicycle like              vehicles are older than that. Historians do agree that Ernest Mich aux did invent a bicycle with pedal and rotary cranks in 1861. However, they disagree if Mich aux made the very first bike with pedals. Another fallacy in bicycle history is that Leonardo Davin's sketched a design for a very modern looking bicycle in 1490. This has been proven to be untrue.

The Celerifere

The celerifere was an early bicycle precursor invented in 1790 by Frenchmen, Comte Mede de Sivrac. It had no steering and no pedals but the celerifere did at least look somewhat like a bicycle. However, it had four wheels instead of two, and a seat. A rider would power forward by using their feet for a walking/running push-off and then glide on the celerifere.

The Steerable Laufmaschine

German Baron, Karl Drais von Sauerbronn invented an improved two-wheel version of the celerifere, called the laufmaschine, a german word for "running machine". The steerable laufmaschine was made entirely of wood and had no pedals; a rider would push his/her feet against the ground to make the machine go forward. Drais' vehicle was first exhibited in Paris on April 6, 1818.

Velocipede

The laufmaschine was renamed the velocipede, latin for fast foot, by French photographer and inventor, Nicephore Niepce, and soon became the popular name for all the bicycle-like inventions of the 1800s. 

Mechanically Propelled

In 1839, Scottish inventor Kirkpatrick Macmillan devised a system of driving levers and pedals for velocipedes, that allowed the rider to propel the machine with feet off the ground. However, historians are now debating if Macmillan actually did invent the first pedaled velocipede, or if it was just propaganda by British writers to discredit the following French version of events.
The first really popular and commercially successful velocipede design was invented by French blacksmith, Ernest Michaux in 1863. A simpler and more elegant solution than the Macmillan bicycle; Michaux's design included rotary cranks and pedals mounted to the front wheel hub. In 1868, Ernest Michaux founded Michaux et Cie (Michaux and company), the first company to manufacture velocipedes with pedals commercially.

Penny Farthing

The Penny Farthing is also referred to as the "High" or "Ordinary" bicycle, and the first one was invented in 1871 by British engineer, James Starley. The Penny Farthing came after the development of the French "Velocipede", and other versions of early bikes. However, the Penny Farthing was the first really efficient bicycle, consisting of a small rear wheel and large front wheel pivoting on a simple tubular frame with tires of rubber.

Safety Bicycle

In 1885, British inventor John Kemp Starley designed the first "safety bicycle" with a steerable front wheel, two equally-sized wheels, and a chain drive to the rear wheel.
