Modern bicycle computers (actually electronic bicycle speedometers) display the current speed of the bicycle, but don't record the data so that a history of the motion can be investigated later. Euler et al.1 devised a method using an ordinary cassette audiotape recorder to store up to two hours of speed data. This paper describes another method employing the LabPro6 interface that was used to capture a record of the speed of a bicycle coasting to a stop.
