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.

Rotating weight Mass that is rotating while the bike is moving, which is a form of inertia. A bicycle wheel can be approximated as a hollow cylinder with most of its mass near the rim. The rotation of the cranks, hubs, and other parts are less significant because both their radius and rotational speed are smaller.
Bicycle and motorcycle dynamics is the science of the motion of bicycles and motorcycles and their components, due to the forces acting on them. Dynamics falls under a branch of physics known as classical mechanics. Bike motions of interest include balancing, steering, braking, accelerating, suspension activation, and vibration. The study of ...
Exercise bikes are used for exercise, to increase general fitness, for weight loss, and for training for cycle events. The exercise bike has long been used for physical therapy because of the low-impact, safe, and effective cardiovascular exercise it provides. The low-impact movement involved in operating an exercise bike does not put much ...
The price of a new bicycle can range from US$50 to more than US$20,000 (the highest priced bike in the world is the custom Madone by Damien Hirst, sold at US$500,000 [10]), [11] depending on quality, type and weight (the most exotic road bicycles can weigh as little as 3.2 kg (7 lb) [12]).
A carbon fiber frame racing bicycle by the French company LOOK A road bicycle made by Scott Lance Armstrong riding in a posture often used on a road bicycle. A racing bicycle, also known as a road bike, is a bicycle designed for competitive road cycling, a sport governed by and according to the rules of the Union Cycliste Internationale (UCI).
A Kawasaki sport bike at a track day at Lakeside International Raceway. The groundbreaking inline four of the Honda CB750.. A sports motorcycle, sports bike, or sport bike is a motorcycle designed and optimized for speed, acceleration, braking, and cornering on asphalt concrete race tracks and roads.
A downhill bike (also known as a downhill mountain bike) is a full suspension bicycle designed for downhill cycling on particularly steep, technical trails. Unlike a typical mountain bike, durability and stability are the most important design features, compared to lighter, more versatile cross-country bikes.
