Abstract: An adjustable handlebar mounting assembly adapted to mount above the head tube of a bicycle frame includes a pair of inserts, each of which has a generally cylindrical inner surface formed and adapted to at least in part encircle the bicycle steerer tube. Each of the inserts has a generally arcuate exterior surface, the axis of which is generally perpendicular to the axis of the generally cylindrical interior surfaces. There is a front cap and a back cap, each of which has an interior surface which mates with the exterior surface of an insert. Fasteners secure the caps together and in tight engagement with the exterior of the inserts. A stem extension tube is attached to the front cap and a handlebar is mounted to the stem extension tube. The mating surfaces of the inserts and caps are adjustable in their relative positions, whereby the position of the caps relative to the inserts and the bicycle frame, and thus the angle of the stem extension relative to the frame, is adjustable.

Abstract: A bicycle handlebar construction provides a handlebar having first hand gripping portions and a forward extension having second hand gripping portions. There is a pair of arm rests mounted on the handlebars for support of a rider's arms when using the forward or second hand gripping portions. There are means for positioning the arm rests a distance away from the first hand gripping portions to prevent interference therewith when the rider is using the first hand gripping portions.

Abstract: A bicycle handlebar includes a main bar which is conventionally attached at its midpoint to a bicycle stem. There is a pair of auxiliary bars each having a hand-gripping portion thereon. Each auxiliary bar is attached to the main bar to provide for multi-axis movement about the main bar. The attachment for each auxiliary bar includes an adjustment member which can tighten or loosen the connection so that the location and position of each auxiliary bar suits the need of the rider of the bicycle.

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.

Abstract: A linkage for attaching an auxiliary handlebar having tubular ends to a bicycle handlebar having tubular ends includes a first member adapted to be axially secured and rotationally movable within each tubular end of the auxiliary handlebar and an adjustable linkage adapted to be variably positioned within each tubular end of the bicycle handlebar. Each adjustable linkage is pivotally attached to a first member in mounting the auxiliary handlebar to the bicycle handlebar.
