1. Handlebars for a bicycle, the handlebars comprising:
a left arm section having a left proximal end and a left distal end; a right arm section having a right proximal end and a right distal end; a base section having left and right base ends; a left pivot mechanism operatively coupling the left arm section proximate the left proximal end to the base section proximate the left base end; a right pivot mechanism operatively coupling the right arm section proximate the right proximal end to the base section proximate the right base end; a left actuator mechanism configured to permit rotation of the left pivot mechanism to move the left arm section relative to the base section between first and second left arm positions when the left actuator mechanism is actuated by a left hand of a user while the left hand is resting on and in contact with the left arm section; a right actuator mechanism configured to permit rotation of the right pivot mechanism to move the right arm section relative to the base section between first and second right arm positions when the right actuator mechanism is actuated by a right hand of a user while the right hand is resting on and in contact with the right arm section; wherein (i) each of the left and right pivot mechanisms comprise (a) an inner cylinder having an annular outer surface of a first diameter and defining an axis of rotation and (b) an outer cylindrical tube having an annular inner surface of a second diameter, the second diameter being larger than the first diameter and defining a longitudinal axis thereof, (ii) the outer cylindrical tube is fixedly attached to a respective left or right distal end, (iii) the inner cylinder is fixedly attached to a respective left or right base end, and (iv) the outer cylindrical tube is at least partially rotatably received over the inner cylinder with the axis of rotation and the longitudinal axis being coincident with each other; wherein each of the left and right actuator mechanisms comprises a lock pin, an actuator lever, and a connector coupling the lock pin with the actuator lever; wherein the actuator lever of the left actuator mechanism is pivotally coupled with the left arm section at an intermediate location between the distal and proximal ends thereof, and the actuator lever of the right actuator mechanism being pivotally coupled with the right arm section at an intermediate location between the distal and proximal ends thereof; wherein the inner cylinder includes at least two radially extending cylinder bores that are similarly positioned along the axis of rotation and spaced circumferentially from each other on the annular outer surface; wherein the outer cylindrical tube includes at least one radially extending tube bore located at a similar position along the axis of rotation as the two radially extending cylinder bores; and wherein the lock pin is received in the radially extending tube bore and is adapted to move radially therein when the lever is actuated; and wherein the lock pin is selectively received in one or the other of the two radially extending cylinder bores when the one radially extending cylinder bore is aligned with the radially extending tube bore. |
