- <h1>The Evolution of the bicycle</h1>
- <div class="prvystlpec">
- <h2>The First Bicycle</h2>
- <p class="prvy">In 1817 Baron von Drais invented a walking machine that would help him get around royal gardens faster: two same-size in-line wheels, the front one steerable, mounted in a frame upon which you straddled. The devgice was propelled by pushing your feet against the ground, thus rolling yourself and the device forward in a sort of gliding walk.</p>
- <p>The machine became know as the Draisenne (or "hobby horse"). It was made entirely of wood. This enjoyed a short lived popularity as a fad, not being practical for transportantion in any other place than a well maintained pathway such as in a park or garden.</p>
- <h2>Further Innovations</h2>
- <p>The next appearance of a two-wheeled riding machine was in 1865, when pedals were applied directly to the front wheel.
- This machine was known as the velocipede (meaning "fast foot") as well as the "bone shaker," since its wooden structure combined
- with the cobblestone roads of the day made for an extremely uncomfortable ride. They also became a fad and indoor riding academies,
- similar to roller rinks, could be found in large cities.
- <p>In 1870 the first all-metal machine appeared. (Prior to this, metallurgy was not advanced enough to provide metal which was strong enough to make small,
- light parts out of.) The pedals were attached directly to the front wheel with no freewheeling mechanism. Solid rubber tires and the long spokes of the
- large front wheel provided a much smoother ride than its predecessor.
