Record speed on the bike. Maximum speed
What is the maximum speed that a person can develop while riding a bicycle? There are many records achieved in different conditions, in different situations and at different times.
Speed of cycling
An ordinary untrained person, nowherehurrying, on the city route can move at a speed of about 12-15 km per hour, if you take into account the descents and the ascent of the road. This value is taken as the average speed of the bike.
A slightly training person on a bicycle withcertain amenities (for example, there are available Tuklips, gearshift, good brakes) is able to move faster - at a speed of 30 km / h.
And if the same person is transplanted tohighway lightweight bicycle, for example, without a rear and a front wing, then on the flatest part it can accelerate it to 40 km / h and continue to hold this speed for several minutes.
There are not only speed records onbike, but also world records for speed retention. In 2005, on the famous cycle track in Krylatskoe, the representative of the Czech Republic O. Sosenka kept the achieved speed (49.7 km / h) on the bike for 60 minutes. He could not hold the value of 50 km / h due to the fact that his bike had only one gear and a rather high saddle. Such a record is complicated by the wear and tear of forces.
On good roads, you can9 km downhill calmly maintain a high speed of 60-70 km / h, even on heavy mountain bikes. It turns out that for the maximum speed for ordinary cyclists, these values should be taken.
How did it all begin?
Cyclist Jose Meifret established the worlda record speed on a bicycle (204.73 km / h) in 1962 in Friedberg (Germany). And it all started before. Since the very creation of the bike, many attempts have been made to achieve maximum driving speed.
Perhaps, it is worth talking about the most significant and important records in the history of the development of this sport, and even the transport itself.
In 1899, Charles Murphy, practicing around2 months, decided to put a record speed drive in Long Island by rail. To do this, it was necessary to attach one car to the locomotive and equip it with a hood so that the cyclist could escape from the wind. At first, due to the error of Murphy himself, he fell behind the train, but then after all caught up with him. Thus, in June 1899, a maximum speed record was set. It was 100.2 km / h.
The next speed record on the bike waswas delivered only in 1937. This happened in Los Angeles (California). The record holder Albert Marquet moved behind the car, which was also equipped with a fabric frame so that the cyclist would move inside it. His record was 139 km / h.
In 5 years, in 1942, a newrecord (again in California). And in this case the car ahead was racing, and the bicycle was improved. At that time, record-holder Alf Leturne developed the highest speed on a bicycle.
The record was fixed at 175 km / h. But on this world achievements have not ended.
Records. World record of speed on a bicycle
Absolute speed record on a bicyclewas established in 1995. Its value is 268.8 km / h. This was achieved by the Dutchman Fred Rompelberg. The record was important and valuable not only for the rider, as he turned 50 this year.
This event took place on the track in Utah(USA). It was an ideal flat surface of an ancient lake (salt), this is the Bonneville plain. And the bike was specially equipped (significantly increased gear ratio and special transmission system to the rear sprocket). And, as always, in front of him was moving car, which also created behind itself a zone of reduced pressure.
Speed record on a mountain bike
Descents from the mountains can also be under different conditions: on the ice surface and ground. Therefore, the records are divided.
On a winter track on a mountain bike, with a beautifulequipment of transport (excellent aerodynamics of the bike, aerodynamic outfit), the speed record on the bike is firmly held by the athlete Eric Baron. In 2000, in the Alps (April 12), he dispersed his bicycle to 222 km / h.
Despite the fact that he descended from the mountain, histhe record was lower than the absolute (F. Rompelberg). And yet you need to take into account that the resistance of the air during descent has increased more and more, and the vibration has increased, worsening the stability of transport. This vibration also prevented him from setting a record on the gravel descent (a sad finish).
Two years later on the slope of the city Sierra Negro the same athlete took the third place, after the previous one's own second, literally "driving" about 400 meters down the gravel. It was a real hell for the cyclist: at the finish of this terrible gap, the maximum speed of the bike reached 210.4 kilometers per hour, and his bike literally exploded.
Good training, competent protection and a quality helmet helped Baron survive in such a deadly situation.
There is no limit to human and technical capabilities. Man will always strive to conquer new heights.
