1. A wheelchair comprising:
a frame;
a caster wheel assembly coupled to the frame and translatable relative to the frame;
a limiter coupled to the frame and movable relative to the frame from a disengaged position to an engaged position, the limiter configured to restrict the translation of the caster wheel assembly relative to the frame when the limiter is in the engaged position;
an actuator supported by the frame and operably connected to the limiter; and
a first biasing member coupled to the limiter,
wherein the first biasing member is configured to urge the limiter toward the engaged position when the actuator is in a first condition and the actuator is configured to urge the limiter toward the disengaged position when the actuator is in a second condition.
