Abstract
A bicycle speed change lever assembly comprises a tubular body (7) pivotally supported on a lever shaft (9) which is located inwardly and downwardly relative to an end grip portion (2) of a handlebar (1) and extends downward, and a control arm (8) extending radially outward from the tubular body. The following measure is taken for enabling speed change operation while gripping the grip portion (2) of the handlebar (1), for enlarging the pivotal range of the control arm (8) to increase the number of speed stages, and for enabling smooth pivotal operation of the control arm (8). The control arm (8) has a first operating arm portion (13) which provides a pivotal path immediately under the handlebar (1) or grip portion (2), and a second operating arm portion (14) which provides a pivotal path spaced from the underside of the handlebar (1) or grip portion (2) by a predetermined distance.
