ABSTRACT:
An attachment assembly for a bicycle handle bar provides an extension bar as well as a brake operating device therefor. The extension bar, together with the handle bar, provides a pair of gripping portions, while the brake operating device provides a pair of hand portions for operating a brake. The brake operating device is coupled to the free end of the extension bar and provides a pair of hand portions such that the rider can grasp the first hand portion from the extension bar and the second hand portion from the grip portion formed on the primary handle bar. In a first embodiment, the brake operating device is integrally formed as a one-piece, unitary member with a part of the extension bar, while in another embodiment, the brake operating device is formed as a separate unit which is releasably coupled to the extension bar. In one embodiment, each of the first and second hand portions extends outwardly from a connecting portion to a free end, while in another embodiment, the second hand portion extends from one end of the first hand portion.
