Abstract: The present invention is a bicycle trainer that allows a person to utilize their own bicycle and simulates real and varied road conditions. The device includes the front forks of a bicycle mounted to a stand; the stand including a flexible support arm allowing the bicycle to rock back and forth along a rocking arc; and the rear tire of the bicycle making contact with a roller face of a roller such that the roller is free to rotate in proportion to the rotation of the rear tire. Further, the roller is rotationally connected to a motor for selectively applying resistance and assistance to the rear tire rotation, for simulating real course conditions. Preferably it further includes a motor assembly which includes a frame for housing the roller and motor and rigidly connecting the motor assembly to the stand, the motor is pivotally mounted to the frame about its shaft, such that the motor and roller rotate in proportional unison with each other.
