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 ]
Cadence (cycling) In cycling, cadence is a measure of rotational speed of the crank, expressed in units of revolutions per minute (r/min or rpm). In other words, it is the pedalling rate at which a cyclist is turning the pedals. Cadence is directly proportional to wheel speed, but is a distinct measurement and changes with gearing.
A bicycle gearbox with chain tensioner. Bicycle gearing is the aspect of a bicycle drivetrain that determines the relation between the cadence, the rate at which the rider pedals, and the rate at which the drive wheel turns. On some bicycles there is only one gear and, therefore, the gear ratio is fixed, but most modern bicycles have multiple ...
On land, the speed record registered by a rider on a 200-meter flying start speed trial was 133.28 km/h (82.82 mph) by the Canadian Sam Whittingham riding the Varna Tempest, a streamliner recumbent bicycle in 2009, [19] at Battle Mountain, Nevada. His record has been surpassed by 0.5 km/h by Sebastiaan Bowier of the Netherlands in 2013 setting ...
Long slow distance. Long slow distance (LSD) is a form of aerobic endurance training used in sports including running, [1] rowing, [2] skiing [3] and cycling. [4][5] It is also known as aerobic endurance training, base training and Zone 2 training. [6] Physiological adaptations to LSD training include improved cardiovascular function, improved ...
The metabolic equivalent of task (MET) is the objective measure of the ratio of the rate at which a person expends energy, relative to the mass of that person, while performing some specific physical activity compared to a reference, currently set by convention at an absolute 3.5 mL of oxygen per kg per minute, which is the energy expended when sitting quietly by a reference individual, chosen ...
Bicycle drivetrain systems have been developed to transmit power from riders to drive wheels by a variety of methods. Most bicycle drivetrain systems incorporate a freewheel to allow coasting, but direct-drive and fixed-gear systems do not. The latter are sometimes also described as bicycle brake systems. A belt-drive crankset.
Gear inches is an imperial measure corresponding to the diameter in inches of the drive wheel of a penny-farthing bicycle with equivalent (direct-drive) gearing. A commonly used metric alternative is known as metres of development or rollout distance, which specifies how many metres a bicycle travels per revolution of the crank.
