VAM is a parameter used in cycling as a measure of fitness and speed; it is useful for relatively objective comparisons of performances and estimating a rider's power output per kilogram of body mass, which is one of the most important qualities of a cyclist who competes in stage races and other mountainous [citation needed] events.
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 performance is measurable performance such as energy efficiency that affect how effective a bicycle is. Bicycles are extraordinarily efficient machines; in terms of the amount of energy a person must expend to travel a given distance, cycling is calculated to be the most efficient self-powered means of transportation .
Both "gear inches" and "metres of development" are concerned with the distance travelled per turn of the pedals, and are ultimately ways of indicating the mechanical advantage of the drivetrain, but neither of them take into account the length of the crankarm, which can vary from bike to bike. The crankarm is a lever arm.
The resale value of a vehicle is often strongly influenced by the total distance shown on the odometer, yet odometers are inherently insecure because they are under the control of their owners. Many jurisdictions have chosen to enact laws which penalize people who are found to commit odometer fraud .
Note that, on a bicycle, as rake angle increases, head angle decreases. Trail can vary as the bike leans or steers. In the case of traditional geometry, trail decreases (and wheelbase increases if measuring distance between ground contact points and not hubs) as the bike leans and steers in the direction of the lean.

The company reports market value prices for new and used automobiles of all types, as well as motorcycles, snowmobiles and personal watercraft. [16] For both new and used automobiles, Kelley Blue Book provides a fair market range and fair purchase price, based on actual transactions of what others are paying for a vehicle and adjusted regularly as market conditions change.
Walk Score was founded in July 2007 by Mike Mathieu [3] [4] and aided by Matt Lerner, Jesse Kocher, and Josh Herst, formerly of Madrona Venture Group.. In August 2010, the company launched Transit Score to help users understand the proximity of public transport to an address.
