An arm support for a personal mobility vehicle can include a first member having a first end that defines a first cavity, and a first attachment member that extends through the first cavity so as to define an axis. The arm support can further include a second member having a first end that is disposed within the first cavity such that the second member is pivotally attached to the first member by the first attachment member. The arm support can further include an actuator that extends through the first end of the second member and through the first cavity. The actuator can be operatively coupled to the second member such that actuation of the actuator causes the second member to pivot about the axis.
