Abstract: A new and unique highly adjustable stationary exercise bicycle 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 is a lubrication port that allows 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. 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.

Abstract: A unique abdominal bench with a pivoting torso section has a number of pivots, rods, and levers that allow the fixed seat section, of the abdominal bench to remain a constant distance from the pivoting torso section during an abdominal exercise. The leg section of the abdominal bench pivots towards the abdomen, as does the torso section when the torso is raised. The leg section is pivotably connected to the torso section through a number of rods, pivots and levers such that the gap between the seat and torso section remains the same. A push rod is connected to the pivoting leg brace and is in turn connected to a torso bracket through several guide rods and a dog-leg lever. The push rod, guide rods and the dog-leg lever allow the torso section to remain a constant distance from the fixed seat section.

Abstract: A stabilizing tracking system for a spinner exercise bicycle includes a spool that is attached to the bike in the loop path of the drive belt between the drive and flywheel sprockets. The spool is located such that the belt is forced to travel below the top dead center of the flywheel sprocket. The spool also has flanges such that the standard poly-V-belt is caused to track within the spool. Forcing the belt below top-dead center of the flywheel sprocket and keeping the belt in tack reduces belt wear, stretching, and the tendency of the belt to wobble or sway as it is driving a flywheel. The spool utilizes inner bearings for smooth rotation of the stability tracking spool. The spool compensates for the differential in the thrust from the top, dead center position of the drive sprocket. The spool picks up the slack in the drive belt that and keeps the belt in a close track. The spool also compensates for slippage during start up of the flywheel and keeps the belt from slipping or wobbling.

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 is a lubrication port that allows the surface between the friction member and the working wheel to be lubricated.

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.

Abstract: A variable resistance abdominal bench is presented which has adjustable feet and handles. The adjustable feet and handles allow the bench to be adjusted to the size of the particular user of the equipment. The bench also has a torso part and a seat part. The torso and seat parts are pivotable. Attached to the torso part of the bench is a weight that slides along a track underneath the torso part. The weight can be placed on either side of the pivot point so that a negative or positive resistance can be created. The exerciser thus has the option of doing an assisted sit-up or doing a sit-up against an added weight.
