A shift control apparatus for a hub transmission includes an axle defining an axle axis; a pawl support rotating member rotatably supported around the axle axis; a pawl rotatably supported to the pawl support rotating member; a biasing mechanism for biasing the pawl in a radial direction; and a pawl

A shift control apparatus for a hub transmission includes an axle defining an axle axis; a pawl support rotating member rotatably supported around the axle axis; a pawl rotatably supported to the pawl support rotating member; a biasing mechanism for biasing the pawl in a radial direction; and a pawl control rotating member for controlling a radial position of the pawl. One of the pawl support rotating member and the pawl control rotating member includes a location for coupling to a shift control mechanism, and the other one of the pawl support rotating member and the pawl control rotating member includes a location for coupling to an actuating member. A spring is provided for biasing the pawl support rotating member and the pawl control rotating member in a rotational direction relative to each other, and a stopper is provided for holding the pawl support rotating member and the pawl control rotating member in a rotational position relative to each other. The actuating member rotates the pawl support rotating member and the pawl control rotating member in an opposite rotational direction relative to each other when resistance from the shift control mechanism overcomes a biasing force of the spring.
