A new and unique highly adjustable stationary exercise bicycle for children or adolescents is presented incorporating a number of features specifically designed for youthful stationary bicycle users. The improvements over the prior art include infinitely adjustable vertical and horizontal seat heights and handlebar heights which are secured in their positions by a quick release lever rather than the standard pop pins. Also included are ports which allow the surface between the friction member and the working wheel to be lubricated. An emergency brake for the working wheel as well as a quick way to disengage the working wheel from the pedals is provided. A one-way directional clutch bearing also allows the user to "coast" on the bicycle, with the pedals remaining stationary while the working wheel is still moving. Special pedal cage brackets are placed around each pedal so that the youth's use of such an exercise bicycle is made much more safely. All of the above elements combine to make this stationary exercise bicycle safe for use by children or adolescents.
