Abstract: A secure but inexpensive quick release mechanism for a bicycle trainer includes a cam housing secured to a trainer support base, a cam follower that securely engages a bicycle rear axle and is slideable between opposite engagement and release positions and a rotatable cam connected to drive the cam follower between the engagement and release positions in response to rotation of the cam. The trainer further includes an adjustable fastener supported on the base on a side of a bicycle rear axle opposite the quick release mechanism and a fan mechanism coupled to be driven by a supported wheel to provide a drag that increases with wheel rotational velocity.

Abstract: A foldable bicycle carrier for carrying bicycles and the like on automobiles and other vehicles is disclosed. The subject carrier is characterized by a unitary hanger member to which is movably attached a pair of legs. A locking mechanism serves to rotably attach each of the legs to the hanger member such that the subject carrier is able to be folded flat to have both the legs and the hanger member be in a single plane when the carrier is not in use. The locking mechanism also serves to lock each of the legs when the carrier is in an extended operative configuration to prevent accidental collapse or folding.
