Since the 5 century scholars had already tried to invent a vehicle
drtiven by human power. However the really popular mean of transport similar to today´s
bicycle became so called trolley. German Karl Friedrich Drais constructed it in the
year 1813, after whom it also started to be called. The trolley was in fact a sort of
scooter for adults. The rider sat astride on it and ... during the drive with his legs
from the soil. There were no pedals there, only wooden wheels, very simple seat and
primitive handle-bars. The idea itself was known earlier, Drais invented turning
controllable front wheel by himself. For this he recieved in the year 1818 a patent.





In 1885 the first predecessor of a real low bicycle appeared: “Rover Safety”, made by William Sutton and John Starley. The only way how to prove the superiority of the low bike over the high one was a victory on a race course. Around 80´s in 19th century plenty of such victories were done. Some adherents of the high bikes couldn’t believe their eyes, when seeing the low rover – the low bikes were called so in general – driving in the goal straight as the first one.
The success of rovers was unambiguous. Also because in those times tyres were starting their victorious journey through the world.
At the break of the 19th and 20th century the technical arrangement of the bike (frame’s construction, conveyances and steering) was similar to the today’s arrangement. The only thing which the old bikes did not have were save brakes. In those times no freewheel existed. The conveyance lead to a firm axis of the back wheel and if this wheel was turning the pedals were turning too.


When going downhill the small brake on the front wheel (a rubber stump) wasn’t very effective. The only thing, that the rider could do was brakeing by retention of the rotating pedals. This was not comfortable and the driver couldn’t rest even when going downhill. M.Sc. Bowden was the one who helped to get over these difficulties. He invented an axial brake which effected the rim of the front and back wheel from both sides. This brake is known to all nowadays cyclists. A bit later a so called back brake spread in Central Europe and in America. It braked directly in the centre of the back wheel only by reverse pressing. (The producer called this brake “torpedo”.)

Until 1895 bikes were produced without any accessories, only some more expensive
bicycles were equipped with a primitive lantern. At the beginning the bikes did not even
had any fenders. What we call fenders was offered in the 19th century as a “linen
protective belt against mud” and it took some years before fenders became a regular part
of an ordinary travelling bike.

The liking for bicycles made witty brains to adjust the ordinary bike to different purposes. And so a bike was even put on railway track and a donkey engine appeared – an inevitable means of transport used by railway workers for tracks´ inspection. The rise of a military folding bike was also accompanied with certain hope, this bike was carried by the soldier on his back. A bike equipped with floats was called “hydro cycle” and in some days it was widely broaden.

A ride on a bicycle was a great experience, if headwind did not blow and when it wasn’t necessary to go uphill. Therefore the designers tried to remove or at least defuse these inconveniences with a gear. The basis of such gear is the fact, that when the cyclist is going downhill or is riding the bike on a plane then he can use the so called large gear without any problems. But when going uphill or against the headwind it us useful to use smaller gear. The cyclist does go slowlier, but he or she does not have to give off such great effort. The first mutable gear had only two speeds, first in the next few decades it was versatilely improved and the number of gears rose to three of four.

It looked as if the development of bicycles is finished. At the break of 70´s and 80´s of the 20th century another novelty appeared: mountain bikes. But also the “common” bikes are renewed. Those who predicted their end were mistaken: the liking for “cycles” is still great.
