A stationary exercise cycle includes a simulation system for simulating real-world terrain based on environmental and other real-world conditions. Using topographical or other data, an actual location can be simulated. The exercise cycle may include a resistance mechanism that is adjusted based on changes in simulated slope, and by amounts simulating actual frictional and gravitational forces. The simulated speed of the rider, as well as speed and direction of a simulated wind, are used to determine a simulated air speed. Based on the simulated air speed, the simulation system determines the simulated air resistance hindering the rider, and changes reflective of the simulated air resistance are made by the resistance mechanism. The stationary exercise cycle takes into account actual or approximate physical information of the user in determining the real-world conditions that are simulated, including the height, weight, shape, and/or rising position of the rider.
