A bicycle carrier (200) convertible between a first configuration (204) in which one or more bicycles are accommodated and a second extended configuration (206) in which one or more additional bicycles are accommodated for transport on a carrying vehicle (218). The bicycle carrier (200) comprises a vehicle engaging frame (208) configured to be mounted on a carrying vehicle (218) and an elongate rearward extending frame member (120) coupled to the frame (208) at a proximate end (220) of the frame member (120) by a variably configurable hub (222) capable of setting the frame member (120) in a plurality of orientations relative to the frame (208). The frame member (120) accommodates one or more bicycles coupled to the bicycle carrier (200) and a manual actuator (224) operably coupled to the variably configurable hub (222) by a linkage (226). A distal end (124) of the frame member (120) positioned away from the frame (208) is configured to be alternately coupled to: the actuator (224), and an add-on support member (126) that accommodates one or more additional bicycles coupled to the bicycle carrier (200).
