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.
According to a study a human at 70 kg (150 lb) requires about 60 watts to walk at 5 km/h (3.1 mph) on firm and flat ground, [6] while according to a calculator at kreuzotter.de the same person and power output on an ordinary bicycle will travel at 15 km/h (9.3 mph), [7] so in these conditions the energy expenditure of cycling is about one-third ...
[13] [14] The Cyclometer was a mechanical device that counted the number of rotations of a bicycle wheel. [15] A flexible 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.
rattleCAD is a parametric 2D computer-aided design (CAD) software specific for bicycle design, [1] [2] in particular for design bicycle frame, [3] [4] developed by the Austrian cyclist and programmer Manfred Rosenberger since 2008. [5]
Speed limit sign in the Republic of Ireland, using "km/h.". The SI representations, classified as symbols, are "km/h", "km h −1" and "km·h −1".Several other abbreviations of "kilometres per hour" have been used since the term was introduced and many are still in use today; for example, dictionaries list "kph", [3] [4] [5] "kmph" and "km/hr" [6] as English abbreviations.
At Conformity of Production Audits the upper limit on indicated speed is increased to 110 percent plus 6 km/h (3.7 mph) for cars, buses, trucks, and similar vehicles, and 110 percent plus 8 km/h (5.0 mph) for two- or three-wheeled vehicles that have a maximum speed above 50 km/h (31 mph) (or a cylinder capacity, if powered by a heat engine, of ...
VASCAR relies on the accuracy of the patrol vehicle's speedometer drive (generally located within the vehicle transmission) for determining the distance traveled, using an odometer within the VASCAR system itself. Recently-purchased law enforcement vehicles generally have electronic speedometers, and a sensor wire is connected to the speed ...
The most common wheel speed sensor system consists of a ferromagnetic toothed reluctor ring and a sensor (which can be passive or active). The tone wheel is typically made of steel and may be an open-air design, or sealed (as in the case of unitized bearing assemblies). The number of teeth is chosen as a trade-off between low-speed sensing ...
