Abstract
Abstract An adjustable auxiliary handlebar assembly for bicycles and the like include an auxiliary handlebar having arm portions and a hand gripping portion. There are brackets to mount the auxiliary handlebar to the conventional handlebar of a bicycle. The auxiliary handlebar arm portions are mounted to the brackets by the use of extension arms, each of which has an expandable portion. A wedge member and a cooperating threaded rod are used to provide an adjustable connection between the extension arms and the auxiliary handlebar and thus adjustment of the position of the auxiliary handlebar relative to the conventional bicycle handlebar.
