Abstract

The invention discloses a bicycle variable speed bar end which is installed on the front side of the bending part of one end of a bicycle cross handle. The bottom of the variable speed bar end is provided with a brake lever; the inner side part of the variable speed bar end is provided with a variable speed driving lever capable of being wrenched up and down; the front end of the inner side of the variable speed bar end leads a shift cable out and is connected with a wrench in a rotating mode; the other end of the wrench extends to the cross handle and is arranged above the variable speed driving lever; the wrench is composed of a wrench seat and a wrench handle, wherein the wrench seat movably passes through and is sleeved in the shift cable; the wrench seat and the wrench handle are connected in a rotating mode by a spindle; the wrench handle extends to the cross handle and is arranged above the variable speed driving lever; the wrench and the variable speed driving lever can be formed in a whole; and the wrench extends to the cross handle. The invention not only can hook the brake lever to brake the bicycle but also can pull the variable speed driving lever to realize speed variation and improve the safety of a rider on the premise that palms can hold the cross handle.

Description

technical field [0001] The invention relates to the improvement of a bicycle gear shifter handle, in particular to a bicycle gear shifter handle which can simultaneously move a brake handle and a gear shift lever when the handle is held by the palm of the hand. Background technique [0002] The braking of the variable speed bicycle and the speed change are very convenient and flexible, so more and more people are favored. In the prior art, the brake shifting handle is installed on the front side of the bending part of one end of the bicycle handlebar (such as figure 1 As shown), the palm of the cyclist is on the rear side of the bending part, and the brake lever is located at the bottom of the brake shifting handle, which is convenient for the four fingers of the hand to hold and pull. The inner side of the brake shifting handle is provided with a bicycle shifting lever. The front end of the inner side of the brake shifting handle leads to the shifting line. During the ridin...
