ABSTRACT:
A steering handle apparatus for use in a bicycle includes a handle bar and a change-speed lever apparatus for effecting a change-speed operation with a forward operation or a return operation to a home position of its control lever. The control lever is disposed, in the home position, on a side of the handle bar opposed to the other side contacting interdigital pads of a rider's hand gripping the grip portion of the handle bar. Further, the control lever extends towards the grip portion, and the forward operation on this control lever is effected in a direction aligned with a bending direction of the rider's thumb. The improved bicycle steering handle apparatus assures the rider or greater safety by always providing the rider with a good gripping condition and of easier control lever operation.
