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.
