Bicycle Research between Bicycle Policies and Bicycle Culture
Mobility in History, 2014After the Second World War, the bicycle was surpassed by the car as the dominant mode of individual transportation in most Western countries. Since the 1970s, however, bicycle use has again gained some support both from the general public and from governments.

The increase in the use of bicycles has been paralleled by an increase in bicycle accidents. Safety education programs, especially for young people, might reduce the number of injuries.

Pediatrics, 2001
Bicycling remains one of the most popular recreational sports among children in America and is the leading cause of recreational sports injuries treated in emergency departments. An estimated 23 000 children younger than 21 years sustained head injuries (excluding the face) while bicycling in 1998. The bicycle helmet is a very effective device that can

Bicycling injuries can be classified into bicycle contact, traumatic, and overuse injuries. Despite the popularity of cycling, there are few scientific studies regarding injuries. Epidemiological studies are difficult to compare due to different methodologies and the diverse population of cyclists studied.

Scientific American, 1884
I AM obliged to Mr. Housman for pointing out a slip of expression in my review of Mr. Sharp's book. I had not confused the ratio of the I's for the ratio of the D's, but merely inadvertently used the word “stiffness” in its colloquial and more extended sense, so to include resistance to forces which would seriously bend or damage, as well as to those ...

Acta Mathematica Hungarica, 1997
The author considers a more general structure theory of simple semigroups, the basic idea being to give a construction where the term ``group'' is replaced by the term ``monoid'' [see: \textit{D. Rees}, Q. J. Math., Oxf. Ser. 19, 101-108 (1948; Zbl 0030.00802)]. The resulting construction is called a bicyclic extension.

For almost a century the bicycle has been used in the United States as a recreational medium for children and adults. This function has contrasted sharply with that of many other countries, where transportation has been the bicycle's most important use.

Physical Medicine and Rehabilitation Clinics of North America, 1999
The severity of injuries secondary to bicycling range from the pain and nuisance of skin abrasions to life-threatening brain injuries. For most injuries, the key to treatment and prevention is careful assessment of bike fit and training techniques. In general, the treatment of musculoskeletal and neuropathic lesions should follow sound, physiatric ...

SUBSEMIGROUPS OF THE BICYCLIC MONOID
International Journal of Algebra and Computation, 2005In this paper we give a description of all subsemigroups of the bicyclic monoid B. We show that there are essentially five different types of subsemigroups. One of them is the degenerate case, and the remaining four split in two groups of two, linked by the obvious anti-isomorphism of B.

The bicycle towards the pantheon: A comparative analysis of Beijing Bicycle and Bicycle Thieves
Journal of Italian Cinema & Media Studies, 2014Abstract 十七岁的单车/Beijing Bicycle (Wang Xiaoshuai, 2000) is a significant masterpiece of Wang Xiaoshuai, one of the Sixth Generation directors in China that shows a host of similarities with Ladri di biciclette/Bicycle Thieves (De Sica, 1948).
