Abstract: A pedal structure for exercise devices includes a pedal having a groove for receiving an operation rod therein and two positioning ports are defined in a side of the pedal. The positioning ports are continuous notches which are in communication with each other. Two connection ports are located on the operation rod and communicate with the positioning ports. Two positioning members respectively extend through the positioning ports and are engaged with the connection ports. The positioning members are able to slide between the continuous notches so as to adjust the effective length of the pedal relative to the operation rod.

Abstract: A damping assembly for an exercising device includes a shaft with a base member and a rotatable member respectively mounted thereto. The base member has a first annular surface and the rotatable member has a second annular surface which is engaged with the first annular surface with a friction member clamped therebetween. A driving member is connected to the rotatable member and is connected to a power transferring member. An adjustable member is movably mounted to the shaft and a bearing is mounted to the shaft and located between the adjustable member and the rotatable member. The friction between the rotatable member and the base member can be adjustable by moving the adjustable member to compress the rotatable member toward the base member.

Abstract: An angle adjustable handle assembly includes a positioning tube fixedly connected to a handle post of an exercise bike and has a toothed end. A sleeve movably extends through the positioning tube and has a head is on a first end of the sleeve and the head has a toothed shoulder which is engaged with the toothed end of the positioning tube. A second end of the sleeve is threadedly connected to a locking member. A handle extends through the sleeve and a bolt extends through the head of the sleeve and is engaged with the handle. The sleeve and the handle can be pulled to disengage from the toothed end of the tube and rotated to desired angle and then re-engage with the toothed of the tube.
