Abstract

A crank position sensor assembly 1000 for use in combination with an exercise bicycle comprises a set of magnetic elements 1010 fixed in position relative to a crank for rotation with the crank, and at least two sensing elements 1020, 1030 that sense the passing of the magnets 1010. Alternatively, the crank position sensor may comprise two pairs of light sources (525, 526 figure 4) and receivers (530, 540) which detect the passing of teeth or spokes. A processor processes the output signals from the first and second sensing elements or receivers, the processor determining both the position of the crank and its direction of rotation. A controller for a microprocessor based unit is also disclosed which causes images of at least part of a bicycle moving through a scene to be displayed on screen in response to inputs received from one or more sensors fitted to an exercise bicycle of the kind in which the handlebars are free to tilt from side to side during use. The controller receives a first signal from a crank position sensor which is indicative of the position of the crank within a single rotation and a second signal from a handlebar position sensor indicative of the angle of tilt of the handlebar. The controller produces an output signal whose value depends on the co-ordination of rotation of the crank with the tilt of the handlebars that is produced as the rider pedals whilst pulling on the handlebars.
