Apparatus for removably interfacing a bicycle to a computer

1. Field of the Invention An apparatus enables a conventional bicycle to be interfaced to a computer to serve as a controller for electronic games and the like. The apparatus includes a rear wheel support that removably holds the bicycle in an upright position while allowing rotation of the rear wheel. A rear wheel sensor detects rotation of the rear wheel of the bicycle as the rider pedals and generates an electrical signal indicating the rotational speed of the rear wheel. The apparatus also includes a front wheel sensor that detects the direction of the front wheel of the bicycle for the computer through the computer interface. For example, the front wheel of the bicycle can be removably supported by a front support member that rotates about a vertical axis as the front wheel is turned by the handle bars. A potentiometer is used to measure rotation of the front support member, and therefore the direction of the front wheel of the bicycle.
