A bicycle trainer includes a reverse resistance unit mounting arrangement that is configured to increase traction between a bicycle wheel and a resistance unit upon an increase in the speed of rotation of the wheel. The reverse resistance unit mounting arrangement is configured to mount the resistance unit in a suspension-type manner and has an actuator that initially positions the resistance unit against the bicycle wheel. The reverse resistance unit mounting arrangement tends to pivot the resistance unit against the bicycle wheel during use, to automatically bias the wheel toward the resistance unit to prevent slippage between the bicycle tire and the roller of the resistance unit.

1. A bicycle trainer, comprising: a frame that can support a bicycle in a generally stationary position while a user exerts a pedaling effort to rotate a driven wheel of the bicycle during a training session; anda resistance unit that is supported by the frame and that cooperates with the driven wheel of the bicycle so as to resist the pedaling effort of the user, the resistance unit being movable in a tightening direction in which the resistance unit moves toward the driven wheel and in a loosening direction in which the resistance unit moves away from the driven wheel, the resistance unit arranged with respect to the frame so that when a torque that rotates the driven wheel is applied, a normal force between the resistance unit and the driven wheel is increased. 2. The bicycle trainer of claim 1, wherein the resistance unit includes a roller that engages a tire that is mounted to the driven wheel at a contact location and wherein the resistance unit is supported from the frame at a support location that is arranged at a greater height upon the frame than the contact location. 3. The bicycle trainer of claim 2, wherein a hinge for supporting the resistance unit is arranged between the frame and the resistance unit and the support location is defined at a pivot axis of the hinge. 4. The bicycle trainer of claim 3, wherein the tightening direction of movement of the resistance unit is defined by a pivot path that advances toward the driven wheel so that a rotational force of the driven wheel can relatively further tighten an engagement between the driven wheel and the resistance unit that corresponds to the increase in the normal force. 5. The bicycle trainer of claim 3, wherein the hinge includes a hinge barrel and a hinge arm that extends downwardly from the hinge barrel and wherein the resistance unit is interconnected to an end of the hinge arm. 6. The bicycle trainer of claim 4, further comprising an adjuster for moving the resistance unit in the tightening and loosening directions. 7. The bicycle trainer of claim 6, wherein the resistance unit can automatically bias in a tightening direction to increase traction of the tire. 8. A method of using a bicycle trainer, comprising: supporting a bicycle in a frame of a bicycle trainer so that the bicycle is maintained in a generally stationary position while a user exerts a pedaling effort to rotate a driven wheel of the bicycle during a training session;rotating a roller of a resistance unit that is supported by the frame by an engagement of a tire mounted to the driven wheel and the roller of the resistance unit; andincreasing traction of the tire mounted to the driven wheel by automatically increasing the normal force between the resistance unit roller and the driven wheel upon an increase in speed of the driven wheel. 9. The method of using a bicycle trainer of claim 8, wherein a hinge connects the resistance unit and the frame. 10. The method of using a bicycle trainer of claim 9, wherein the resistance unit includes a roller that contacts the tire of the bicycle. 11. The method of using a bicycle trainer of claim 10, wherein the hinge is located above and behind the location of contact between the tire and the resistance unit, such that the hinge will allow the resistance unit to pivot towards the tire in an automatic dynamic biasing movement. 12. The method of using a bicycle trainer of claim 11, wherein the resistance unit has an adjuster that can set an initial resistance applied to the bicycle tire by the resistance unit, and that can move the resistance unit towards the tire in a tightening direction and in a loosening direction to move the resistance unit away from the tire. 13. The method of using a bicycle trainer of claim 12, wherein the hinge and the adjuster allow the resistance unit to move in a generally longitudinal direction toward and away from the bicycle tire. 14. A resistance arrangement for use with a stationary bicycle, comprising: a resistance unit;a resistance unit support structure that is arranged above a surface; anda pivot connection that connects the resistance unit and the support structure, wherein the resistance unit is supported from the pivot connection and the support structure in a suspension-type manner;wherein, when the resistance unit is engaged with a wheel of the stationary bicycle, the resistance unit moves in a tightening direction toward the bicycle wheel upon rotation of the bicycle wheel. 15. The resistance unit of claim 14, further comprising for an actuator arrangement interconnected between the resistance unit and the support structure for selectively moving the resistance unit toward and away from the bicycle wheel.
