A Prototype Construction of Adjustable Bicycle HandlebarsThe riding position of a bicycle is determined by the type of handlebars used. The higher the relationship of the handlebars are to the saddle, the more the rider sits erect and has less stress on the neck, arms and hands. Conversely, the lower the handlebars the more stress forces are felt on those same areas. To manage discomfort and fatigue, the cyclist may stop to rest or sit erect without holding onto the handlebars while still riding. By not holding the handlebars, the rider has little control over steering and no control over braking or changing gears. A solution is to adjust the handlebars from the lower to higher position and still allow access to the hand controls. This project designed and produced a prototype for compound or adjustable bicycle handlebars. The handlebar assembly provides the rider with the ability to change from a mountain bike posture to that of the more comfortable city and classic bike positions while still retaining complete control of steering, braking, and changing gears. Pending positive results from structural testing, the expectation is that the availability of these handlebars will add to the enjoyment of cycling for a larger audience with diverse cycling needs.
