In utility cycling there is large variations in speeds reached. An elderly person on an upright roadster might do less than 10 km/h (6.2 mph) while a fitter or younger person could easily do twice that on the same bicycle. For cyclists in Copenhagen, the average cycling speed is 15.5 km/h (9.6 mph). [11]
John Howard, Olympic cyclist and Ironman triathlon winner, reset the record to 244 km/h (152 mph), also at the Bonneville Salt Flats, on 20 July 1985. Fred Rompelberg from Maastricht, Netherlands was the holder of the motor-paced speed world record cycling with 268.831 km/h (167.044 mph) from 1995 to 2018. [31]
As result, a 28-inch wheel could be made to move a bicycle at the same speed as a 60-inch wheel. Such a bicycle was then said to be geared at 60 gear inches and pedalled similar to an ordinary with a 60-inch wheel. Thus on a bicycle geared at 72 gear inches one revolution of the pedals advances the bicycle the distance that a 72-inch wheel ...
Hour record. The hour record is the record for the longest distance cycled in one hour on a bicycle from a stationary start. Cyclists attempt this record alone on the track without other competitors present. It is considered one of the most prestigious records in cycling. Since it was first set, cyclists ranging from unknown amateurs to well ...
In 1895, Curtis H. Veeder invented the Cyclometer. [1] [2] [3] The Cyclometer was a simple mechanical device that counted the number of rotations of a bicycle wheel.[4] [5] A cable transmitted the number of rotations of the wheel to an analog odometer visible to the rider, which converted the wheel rotations into the number of miles traveled according to a predetermined formula.
Mountain bike racing entered the Olympic programme at the Atlanta Olympics, followed by BMX racing in 2008 and freestyle BMX in 2020. Before the 2020 Summer Olympics, all events were speed races, but the 2020 programme featured BMX freestyle for the first time. Women's road events were introduced to the Olympic programme at the 1984 Summer ...
VAM is the abbreviation for the Italian term velocità ascensionale media, translated in English to mean "average ascent speed" or "mean ascent velocity", but usually referred to as VAM. It is also referred to by the English backronym "Vertical Ascent in Meters". [1] The term, which was coined by Italian physician and cycling coach Michele ...
The equation u - v=at implies that the greater the acceleration the shorter the time needed to change speed. The stopping distance s is also shortest when acceleration a is at the highest possible value compatible with road conditions: the equation s=ut + 1/2 at 2 makes s low when a is high and t is low.
