Abstract:
1. A bicycle trainer, comprising: a frame that can support a bicycle in a stationary position while a user exerts a pedaling effort to rotate a driven wheel of the bicycle during a training session and a resistance unit that can cooperate with the driven wheel of the bicycle so as to resist the pedaling effort of the user, the frame including a pair of side segments that are spaced from each other, each of the side segments including an upper end, and a wheel support system that is arranged at the upper ends of the side segments for supporting the driven wheel, the wheel support system including: a first wheel engagement arrangement interconnected with a first one of the side segments of the frame; a second wheel engagement arrangement interconnected with a second one of the side segments of the frame; an actuation arrangement associated with at least one of the first and second wheel engagement arrangements for selectively moving the first and second wheel engagement arrangements toward each other to an engaged position in which the driven wheel is retained therebetween, and apart from each other to a release position in which the driven wheel is released; and a movable biasing arrangement associated with one of the first and second wheel engagement arrangements, wherein the movable biasing arrangement comprises a spring that applies an outward biasing force on the associated wheel engagement arrangement that urges the associated wheel engagement arrangement toward an extended position, and wherein the spring is compressible upon engagement with the driven wheel so as to accommodate different wheel widths, and wherein the spring is configured and arranged to apply the biasing force to the driven wheel through the associated wheel engagement arrangement and wherein the biasing force of the spring clamps the driven wheel between the first and second wheel engagement arrangements when the first and second wheel engagement arrangements are in the engaged position.
