1. A self-compensating resistance trainer for use with a cycling mechanism having a bicycle wheel, said bicycle wheel rotatable with respect to said cycling mechanism about a first rotational axis, said first rotational axis fixed with respect to said cycling mechanism, said trainer comprising:

  • a frame having a mounting portion adapted to releasably affix said first rotational axis of said cycling mechanism with respect to said frame;

    a pivot arm being pivotably affixed to said frame about a pivot axis;

    a resistance device being rotatable about said pivot axis, said resistance device resisting rotation with respect to said pivot axis, a driven cylinder being rotatable about a central axle affixed to said pivot arm, said central axle being spaced from said pivot axis and substantially parallel to said pivot axis, said driven cylinder imparting rotation to said resistance device;

    a biased contact point located where said driven cylinder contacts said bicycle wheel when said cycling mechanism is affixed to said mounting portion of said frame, said driven cylinder contacting and being urged toward said bicycle wheel by a static biasing force;

    a dynamic biasing force increasing from a relatively low force when said bicycle wheel is stationary and increasing to a relatively high force when said bicycle wheel is rotating said driven cylinder in a first direction, said dynamic biasing force adding to said static biasing when said bicycle wheel is rotating in said first direction, said dynamic biasing force subtracting from said static biasing force when said bicycle wheel is rotating said driven cylinder in a direction opposite said first direction; and

    said dynamic force being sufficient to prevent slippage between said driven cylinder and said bicycle wheel.
