ABSTRACT:
The bicycle gear crank arresting device comprises an axle, a first arresting member and a second arresting member. The axle is fastened pivotally with the five-way tube of a bicycle frame and is provided with a rotary rod. The first arresting member comprises a crank portion having an arcuate section and a linear section, which are connected at an intersection where an inclined line extending from the midpoint of the axis of the axle and forming a predetermined angle with the axis of the axle meets with a straight line extending from the outer side of the gear piece of the first arresting member for a predetermined distance. The linear section is perpendicular to the axis of the axle. The second arresting member has a crank portion corresponding in profile to the crank portion of the first arresting member. The first arresting member and the second arresting member are fastened with the rotary rod of the axle.
