Abstract: An aerobar assembly is arranged to be mounted on the handlebar stem, rather than on the handlebars, of a bicycle. The aerobar assembly in turn supports the handlebars. By mounting the aerobar on the stem, the range of adjustability of the aerobar is greatly increased, and the handlebar is subject to less torsional forces. The aerobar assembly includes a pillar stem having one end secured to the stem and a support structure at a second end for mounting an aerobar bracket, an arm rest support, and handlebar clamps. The aerobar bracket is arranged to permit axial adjustment of aerobar position, while the arm rest support is arranged to enable lateral, horizontal pivoting, vertical swivelling, and fore-aft adjustment of arm rest position independent of aerobar position. The handlebar mount preferably uses C-clamps that can easily be substituted to accommodate different handlebar configurations.

Abstract: Bicycle-used flow deflecting article cabinet mounted on a rear side of a saddle of the bicycle. The article cabinet includes a main body having a curved shape and substantially triangular lateral faces. A front end of the main body is formed with a receptacle in which personal effects of the rider can be conveniently placed. A cover board is disposed on the surface of the main body for openably covering the receptacle. Two lateral sides of the main body are respectively formed with opposite concave indentations and a C-shaped clip is inlaid in an inner wall of each of the indentations for clamping and locating a liquid container. When riding the bicycle, the curved article cabinet provides a flow deflecting effect to balance the center of gravity of the bicycle body and increase the riding speed.
