Abstract
A digital wristwatch having a case and strap also serves as a computer to display speed, distance, and pedaling cadence when temporarily attached to a holder on the bicycle handlebar. Wheel and sprocket sensors are connected to electrical terminals in the holder. The wristwatch is provided with external electrical terminals connected to a microcomputer in the watchcase which uses signals from the sensors when the watchcase is termporarily retained in the holder. The watch mode is converted to bicycle mode by actuating push buttons on the watchcase, which are accessible through windows on the holder.
