The fork offset is the perpendicular distance from the steering axis to the center of the front wheel. In bicycles, fork offset is also called fork rake. Road racing bicycle forks have an offset of 40–50 mm (1.6–2.0 in). [7]
For example, LeMond Racing Cycles offers [44] both with forks that have 45 mm of offset or rake and the same size wheels: a 2006 Tete de Course, designed for road racing, with a head angle that varies from 71 + 1 ⁄ 4 ° to 74°, depending on frame size, and thus trail that varies from 51.5 mm to 69 mm.
Road racing bicycle forks have an offset of 40–55 mm. [2] For touring bicycles and other designs, the frame's head angle and wheel size must be taken into account when determining offset, and there is a narrow range of acceptable offsets to give good handling characteristics. The general rule is that a slacker head angle requires a fork with ...
Jones Counter on the front wheel of a bicycle. To measure road-race courses, the counter is fitted to a bicycle between the left fork leg and the front wheel. [5] The tab or tabs on the large ring gear engage with the spokes, thus providing drive to a Veeder-Root counter.
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 ...
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 ...

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.
