  • Patent number: 7946963
    Abstract: An exercise cycle includes a base frame having front and rear wheels and a seat slidably mounted thereon. A pair of pivotal foot pedals operate a steering mechanism to turn the front wheels toward the left or right. Between the foot pedals is a vertical support bar having a drive pawl at an upper end with a cable spirally wrapped thereabout. A handle affixed to the distal end of the cable is accessible by a rider resting in the seat. A drive chain encompasses a gear on a side of the pawl and a similar gear on the rear wheel axle. Accordingly, a rider sits on the seat, grasps the handle and places the feet on the foot pedals. By pushing with the legs and simultaneously pulling the cable, the rider propels the cycle while simulating the workout typically provided by a rowing machine.

  • Patent number: 7654545
    Abstract: This device is exercise equipment. It is a vehicle that is driven by arm and leg power. The device is a three wheeled vehicle that driven by the movement of the handlebars and the seat. The rider moves the handlebars and the seat back and forth. The handlebars are attached to the wheels by a set of pulleys. When the handlebars are moved back and forth they drive the wheels. The handle bars and the seat are attached to each other so that both the legs and the arm are exercised. Thus, an individual can ride around the town in his vehicle exercising his whole body.

  • Patent number: 6439591
    Abstract: A bicycle which can be driven either by conventional rotation of the pedals, or by reciprocating movement of the saddle on the seat post. The cycle includes two frame portions: a first fixed frame portion including an upright member extending from a drive wheel axle bearing, and a second movable frame portion including the seat post which has bifurcated arms driving transmission levers for turning the drive wheel.

  • Patent number: 5606207
    Abstract: A power generating apparatus for a bicycle, in particular, a racer type bicycle such as a road racer and a mountain bike, is disclosed. The power generating apparatus of the present invention composed of a power generating unit and a mount stay having suitable means for mounting the power generating unit on a bicycle. In this power generating unit, a rotor is integrated with a cylindrical circumference portion of a housing of the power generating unit. The mount stay is fitted on a front portion of a frame of a bicycle with a bolt. On this mount stay, the power generating unit is detachably mounted so that the rotor may rotate by the tire of the bicycle in contact with the cylindrical circumference portion of the rotor.

  • Patent number: 3948542
    Abstract: Additional propelling power for a bicycle is provided by mounting the bicycle seat to reciprocate in an up and down direction and converting this motion into rotary motion by a ratchet gear. Rotation of this ratchet gear takes place when the seat moves down under the weight of the bicycle rider, a compression spring returning the seat to its up position when the rider lifts his weight from the seat. The motion of the ratchet gear is imparted to the rear wheel of the bicycle through a gear train which amplifies the rotary motion and further which may be provided with a gear shift mechanism for varying the number of rear wheel rotations imparted for one down stroke of the bicycle seat. The auxiliary seat drive is provided in addition to the conventional pedal drive sprocket and chain arrangement normally provided on bicycles.
