German Wehrmacht bicycle troops. Although multiple-speed bicycles were widely known by this time, most or all military bicycles used in the Second World War were single-speed. Bicycles were used by paratroopers during the war to help them with transportation, creating the term "bomber bikes" to refer to US planes dropping bikes for troops to ...
The first cycle race covering a distance between two cities was Paris–Rouen, also won by James Moore, who rode the 123 kilometres dividing both cities in 10 hours and 40 minutes. [4] The oldest established bicycle racing club in the United States is the St. Louis Cycling Club.
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 ...
A bicycle, also called a pedal cycle, bike, push-bike or cycle, is a human-powered or motor-assisted, pedal-driven, single-track vehicle, with two wheels attached to a frame, one behind the other. A bicycle rider is called a cyclist, or bicyclist. Bicycles were introduced in the 19th century in Europe. By the early 21st century there were more ...
In the early 1860s the first true bicycle was created in Paris, France, by attaching rotary cranks and pedals to the front wheel hub of a dandy-horse. The Olivier brothers recognized the commercial potential of this invention, and set up a partnership with blacksmith and bicycle maker Pierre Michaux, using Michaux's name, already famous among enthusiasts of the new sport, for the company.
It was almost 40 years until "velocipede" came into common usage as a generic term, with the launch of the first pedal-equipped bicycle, developed by Pierre Michaux, Pierre Lallement and the Olivier brothers in the 1860s. The Michaux company was the first to mass-produce the velocipede, from 1857 to 1871. That French design was sometimes called ...
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]).
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.
