Comte Mede de Sivrac?
Date of Deathof Mede de SivracMede de Sivrac invented the bicycle in 1791. Nothing else is known about the man, not even when he was born or died. This is probably because he never lived.The bicycle was invented in 1817 by a German called Karl Drais. This early version was known as a Draisienne. a French name because it was really the French who developed the invention during the 19th century.By the end of the century the Germans had built their Empire, defeated France in the war of 1870 and taken two provinces, alsace and lorraine, away from France. When, in 1891, a frenchman, Baudry de Saunier, wrote a History of the Bicycle, he couldn't bear to think that this very French object had been invented by a German.So he invented Mede de Sivrac, the French inventor of the bicycle. His machine was called the celerifere, and it was a bit like the Draisienne, with no pedal, no brakes, and - uniquely - no steering. As (unsurprisingly) French museums had no examples of this machine, a few copies were made up from the 'original plans'. The thing was totally impractical.In fact, there was a M. Sievrac who patented a 'Celerifere' in 1817; but this was a horse-drawn vehicle.French Wikipedia says that de Saunier's deception was discovered quite recently; but it gives no detailed source for this information. In fact, the revelation was made by Jacques Seray in his book 'Deux roues - La véritable histoire du vélo' Ed. du Rouergue, 1988.
Who is Isaac R Johnson?
It is a misconception that Isaax Johnson invented the bicycle frame. He did patent a modern looking folding bicycle frame in 1899. Its parts could be taken apart for more compact storage. Prior to Johnsons invention, Comte Mede de Sivrac and Karl von Sauerbronn built primitive versions of the bicycle in 1791 and 1816 respectively. The frame of John Starley's 1885 "safety bicycle" resembled that of a modern bicycle. Following Starley, there was an early bike design by Harmon D. Moise which included a freewheel that allowed the rider to coast, and the pedals would remain in one position during coasting.
What is one invention made in Germany?
The earliest bicycle was a wooden scooter-like contraption called a celerifere; it was invented about 1790 by Comte Mede de Sivrac of France. In 1816, Baron Karl von Drais de Sauerbrun, of Germany, invented a model with a steering bar attached to the front wheel, which he called a Draisienne. It has two wheels (of the same size), and the rider sat between the two wheels, but there were no pedals; to move, you had to propel the bicycle forward using your feet (a bit like a scooter). He exhibited his bicycle in Paris on April 6, 1818.
Who invented the stationary exercise bike?
It was a combination, Ernest Michaux- pedal and cranks, Baro Karl Drais Von Sauerbronn- steering, Comte Mede de Sivrac- frame. Then i am not sure who invented the rollers which you could place a bicycle on top of and exercise stationary.

Who invented bicycles and where?
The invention of the bicycle is often credited to one of two people. Baron Karl Drais von Sauerbronn invented the "Laufmaschine" or "Running Machine" in Germany in 1818. The machine looks very much like a bicycle in that it has two wheels and a steering handlebar. But the Running Machine has no drive train. The Running Machine is propelled by the rider pushing his feet against the ground. Frenchman Comte Mede de Sivrac invented a similar machine several years prior, but this machine did not have steering so it's not often regarded as a precursor to the bicycle. In the 1860's, a french father-son team of carriage makers, Pierre and Ernest Michaux, invented the modern bicycle pedal and crank giving the "running machine" a bit of mechanical propulsion.
Was the bicycle invented in 1764?
Yes. The first bicycle was introduced in 1817 by the German Baron Karl Von Drais and was called a 'Draisine' or a 'Draisienne'. It was a simple wooden construction with a wooden frame supported by two in-line wheels. The rider had to push the vehicle along withe the use of his/her feet while steering the front wheel. In 1865, Frenchmen Pierre Michaux and Pierre Lallement added a mechanical crank drive with pedals on a large front wheel (the velocipede). This creation was made out of iron and wood which improved the reliability of the bicycle. The only way to increase the speed of the bicycle was to enlarge the front wheel which made it more difficult to steer and increased the probability of a crash. In 1868, a Michaux bicycle was brought to Coventry, England by Rowley Turner, sales agent of the Coventry Sewing Machine Company. Later this company became the Coventry Machinist Company. The French model was used as a base for the Coventry Model. The 1890's where the Golden Ages of the Bicycle, with many improvements that occurred in rapid succession. In 1888, Scotsman John Dunlop introduced the first practical pneumatic tire, which soon became the universal standard. Other improvements where the development of the rear freewheel which made coasting possible. In the 1890's this refinement led to the development of the coaster brakes, derailleur gears and cable-pull brakes. These where the first models of the modern bicycle.

It is estimated that by 1900 there were around 10 million bicycles.londonHi the I think " Cycling may have originated in France going back to mid 18th century and in 1818 with Carl von Drais hobby horse it was the Scot Kirkpatrick Macmillan who put pedals on a bicycle 1840"1885- J.K Starley of England devised the more modern bike with chain and gearing that allowed the wheels to be of equal size.
