The bicycle: Technology and culture
2022Bicycle technology, except for its latest manifestations in “smart” bike sharing systems and in e-bikes, hardly attracts attention in analyses of contemporary bicycle use. If at all considered, the bicycle’s characteristics are seen from a car driver’s perspective, qualifying it as slow, physically demanding, vulnerable (“unsafe”) and exposed. Based on

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 Physician and Sportsmedicine, 1980
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

Current Sports Medicine Reports, 2013
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.
