A bicycle trainer includes a frame, a resistance unit interconnected with the frame, and a wheel mounting arrangement for securing the bicycle wheel to the frame. The wheel mounting arrangement includes first and second spaced apart wheel engagement areas, one of which includes a threaded wheel engagement member. A fixed-position threaded actuator member is rotatably interconnected with the frame. Rotation of the actuator member causes extension and retraction of the wheel engagement member, to move the wheel engagement member toward and away from the second wheel engagement area, and to selectively clamp the wheel between the second wheel engagement area and the wheel engagement member. The threads of the actuator member and the wheel engagement member are lead threads, and a guide arrangement is associated with the threaded wheel engagement member for guiding inward and outward movement of the wheel engagement member upon rotation of the actuator member.
