In the absence of aerial-lift bike racks, bikes must be hooked onto an ordinary lift chair (background). A aerial-lift bike rack is a form of aerial lift designed to lift a bike rack instead of a car or chair. Bikes are loaded at one end and unloaded at the other. They may be used on ski hills for summer mountain biking. [16]

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.

Complex intersections with multiple vehicle lanes, bike lanes, and crosswalks are common examples of traffic engineering projects. Traffic engineering is a branch of civil engineering that uses engineering techniques to achieve the safe and efficient movement of people and goods on roadways.
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 .

Some journey planning systems can calculate bicycle routes, [20] integrating all paths accessible by bicycle and often including additional information like topography, traffic, on-street cycling infrastructure, etc. These systems assume, or allow the user to specify, preferences for quiet or safe roads, minimal elevation change, bicycle lanes ...
As the intensity ramps up, your oxygen consumption eventually plateaus—that’s your VO2 max. The final number is recorded in mL/kg/min (milliliters of oxygen per kilogram of body weight per ...
