An apparatus for synchronizing the movement of a stationary bicycle with video effects produced on a video display of a computer, wherein the bicycle has a rear wheel, handlebars, and a pair of front wheel forks operatively engaged with the handlebars. The apparatus includes a motion sensor configured to produce a rear wheel rotation signal which corresponds to the rotation of the rear wheel. The apparatus also includes a handlebar rotation sensor assembly that is configured to produce a handlebar rotation signal which corresponds to the rotation of the handlebars about an axis. A digital signal processor is configured to receive the rear wheel rotation signal and the handlebar rotation signal and transmit output signals to the computer so that a user of the bicycle may interact with the video effects by rotating the rear wheel and the handlebars.
