Abstract: A cycling exerciser includes a base having a seat post extended upward from the middle portion of the base. A pair of cranks are rotatably secured to the base at an axle for supporting a pair of foot pedals and for allowing the user to conduct cycling exercises. A handle is rotatably secured to the base and is coupled to the axle by unidirectional bearings and by a sprocket-and-chain device for allowing the handle to unidirectionally drive the axle and to rotate the cranks when the handle is rotated by the user. A spring member may be used for recovering the handle.

Abstract: An exerciser includes a post having a lower portion rotatably secured to a base. Two bevel gears are secured to the post and the base and are engaged with each other. A pair of foot supports are pivotally supported on the base and are coupled to the bevel gear secured on the base by two cables, such that the foot supports may rotate the post via the bevel gears, and such that the user may twist his body while stepping with the foot supports. The cables may be secured to the bevel gear via a bar which is secured to the bevel gear.

Abstract: An exerciser includes a post having a lower portion rotatably secured to a base. Two pulleys are rotatably supported on the base. Two foot supports are pivotally supported on the base and are coupled to the post by one or two cables which are engaged over the pulleys and the post, such that the foot supports may rotate the post via the pulleys and the cables and such that the user may twist his body while stepping with the foot supports. Two actuators are coupled to the foot supports for applying the resistive force against the foot supports.

Abstract: An exerciser includes a post having a lower portion rotatable secured to a base, and a bevel gear secured to the post and rotated in concert with the post. Another bevel gear is rotatably supported on the base at a pivot shaft and engaged with the bevel gear of the post. A pair of foot supports are supported on the base and coupled to the bevel gears for rotating the post via the bevel gears. A beam is secured to the pivot shaft and coupled to the foot supports. Another beam is rotatably secured on the base for supporting the rear ends of the foot supports in place.

Abstract: An exerciser includes a base having a front pivot shaft and a rear pivot axle. A post has a lower portion rotatably secured to the base and a bevel gear secured to the bottom. Another bevel gear is secured on the pivot shaft and engaged with the bevel gear of the post for allowing the post to be rotated by the bevel gears. A pair of foot supports are supported on the base and each has a front portion pivotally coupled to the pivot shaft for rotating the pivot shaft and to rotate the post via the bevel gears. The rear portions of the foot supports are coupled to the base by cranks.

Abstract: An exerciser includes a base having a front axle for supporting a handle. A pair of foot supports are pivotally coupled to a front post and coupled to the axle for applying a rotational operation to the axle by a rotational movement of the foot supports. A pulley is secured to the rod and a cable is engaged over the pulley and secured to the foot supports for allowing the foot supports to rotate the rod. Two bevel gears are secured to the axle and the rod and engaged with each other for allowing the rod to rotate the axle and the handle.
