Cycling contributes to the society by reducing fuel consumption, traffic congestion, and air and noise pollution. In recent days, cycling has been promoted as more emphasis is given to non-motorized mobility. To attract people towards cycling, safe and comfortable bikeways are needed. -

Furthermore, the burden of lifetime illness is compressed into a shorter period before the time of a person's death, a statement known as compression of morbidity. As a result, people are capable of being more and more active for longer periods and older ages. Considering as well, the fact that most jobs currently, and most likely in the future, involve a lot of office work sitting still, the need for daily exercise becomes critical in many aspects, especially at older ages. Biking can bring these facts together since it can be easily integrated into everyday living as transportation mean. At older ages though, conventional bicycles can present usage requirements and side effects that will prevent people from using them. -

A CONSTANT FORCE BICYCLE TRANSMISSION by Thomas R. Chase A Thesis Project Submitted in Partial Fulfillment of the Requirements for the Degree of MASTER OF SCIENCE in Mechanical Engineering Approved by: Prof. Richard Budynas Thesis Adviser Prof. Dr. Bhalchandra V. Karlekar Department Head Prof. '"egible Signature Prof. Ray C. Johnson DEPARTMENT OF MECHANICAL ENGINEERING ROCHESTER INSTITUTE OF TECHNOLOGY ROCHESTER, NHJ YORK August 1983 A CONSTANT FORCE BICYCLE TRANSMISSION ABSTRACT A prototype design for a human powered automatic transmission intended for use on an ordinary touring bicycle is presented. The transmission is intended to automatically adjust the gearing of the bicycle to maintain an optimum pedal force, regardless of the current riding conditions. Therefore, the transmission eliminates the need for the cyclist to manually adjust the bicycle gearing. The entire transmission is a self-contained unit designed to bolt onto the rear wheel of an otherwise unmodified 27-inch bicycle. The transmission combines a unique adaptation of a commercially popular continuously variable traction drive with a totally mechanical integral feedback controller. The features of the traction drive unique to its application to a bicycle are outlined in detail, along with an analysis of the important traction drive design parameters. -

Availablehere This Journal Article is posted at Research Online. https://ro.ecu.edu.au/ecuworks2013/891 J Sci Cycling. Vol. 2(1), 11-24 REVIEW ARTICLE Open Access Pedal force effectiveness in Cycling: a review of constraints and training effects Rodrigo R Bini1, 2, Patria Hume1, James Croft3, Andrew Kilding1 Abstract Pedal force effectiveness in cycling is usually measured by the ratio of force perpendicular to the crank (effective force) and total force applied to the pedal (resultant force). Most studies measuring pedal forces have been restricted to one leg but a few studies have reported bilateral asymmetry in pedal forces. Pedal force effectiveness is increased at higher power output and reduced at higher pedaling cadences. Changes in saddle position resulted in unclear effects in pedal force effectiveness, while lowering the upper body reduced pedal force effectiveness. Cycling experience and fatigue had unclear effects on pedal force effectiveness. Augmented feedback of pedal forces can improve pedal force effectiveness within a training session and after multiple sessions for cyclists and non-cyclists. -
