Abstract: The present invention is a spin bike pedal load changing means, and foot rest means for use in stationary training, that collectively greatly improves the capabilities of spin bikes over what is currently available in the art. The pedal load changing means allows the calibration of a range of pedal working loads, tailored to the individual rider's capabilities and at the same time can be used as an emergency brake. The foot rest allows for the safe parking of the rider's free leg during one-legged cycling training. The foot rest feature and pedal load change features both effectively increase the performance and safety of the spin bike in use, which is a much-desired feature for health clubs and gyms. The spin bike further allows the instructor to carry out a group class exercise routine, where each rider can set the pedal load changing means on each spin bike to fit their individual strength and stamina capabilities and also allows the rapid changing of pedal load settings to predetermined levels.
