Abstract: A power pedal is provided, including: a shaft, including a first end configured to be assembled to a bicycle crank, a second end and a connection section connected between the first end and the second end, the connection section including a strain sensing module; a pedal body, connected to the second end; a power sensor, including a processing module and a shell member, the processing module being disposed on an outer circumferential wall of the connection section, the processing module including a processing unit and a wireless transmission unit electrically connected to each other, the processing unit being electrically connected to the strain sensing module, the shell member being disposed on the connection section and encompassing the processing module, the shell member including a receiving room, the receiving room being configured to receive a battery which is replaceable and electrically connected to the processing unit.

Abstract: A bicycle pedal includes a body having a fixed member, a movable member, a resilient unit and a link respectively connected to each of a first face and a second face thereof. The link and the resilient unit are respectively located on inside of the movable member. The link contacts the movable member. When the cleat of a bicycle shoe pushes the movable member and the link away from the body, the push end of the link swings away from the body and pushes the cleat to disengage from the peal. The link has a restriction portion located corresponding to outside of the end piece. The restriction portion extends from the link and toward the end piece to prevent the bolt from dropping from the end piece.

Abstract: A pedal assembly includes an axle and a pedal. The pedal has a passage defined therein, and a shoulder is defined in the inner periphery of the passage. An engaging member is engaged with the passage and the axle rotatably extends through the engaging member. The engaging member has multiple pawls which are engaged with the shoulder to connect the pedal and the axle.

Abstract: A vehicle-mounted detecting device for a bicycle comprises a force sensing base, a strain touch member for detecting the direction and magnitude of force, and a sensor contacted with the sensor. The detecting device is assembled to a crank and a pedal shaft of the bicycle in a manner of external hanging. The detecting device may obtain a pedaling force detecting message. The message of the rotating speed and the tilted angle message may be obtained by a cadence sensor which is packaged in a ring housing. The messages are finally transmitted to a smart mobile device by a microprocessor which is mounted at a ring outer base.

Abstract: A bicycle pedal is provided to be releasably secured to a cleat that is attached to a sole of a cyclist's shoe. The pedal includes a spindle, a pedal body mounted for rotation on the spindle and a measuring device. The pedal body has front and rear engaging portions which releasably engage with respective front and rear lips of the cleat when the pedal is secured to the cleat. The measuring device is disposed in the pedal body and includes a sensor configured to detect the tightness between the pedal body and the cleat.

Abstract: A pedal with a sensing device includes a spindle, a frame member, a receiving member and a sensing assembly, the frame member having a treading portion and a receiving channel, the receiving channel being adjacent to the treading portion and having an electricity supplier, the receiving member assembled to the frame member, the sensing assembly having a controlling unit electrically connected to the electricity supplier and a sensing unit electrically connected to the controlling unit. Under this arrangement, when the rider treads on the present invention, the pedal rotates relative to the spindle to generate a force and a rotation speed for the pedal; thereby, the force and the rotation speed of the present invention are detected by the sensing assembly.

Abstract: A bicycle clipless pedal includes a pedal, a locking sheet pivotally mounted on the pedal, and a plastic elastomer located between the pedal and the locking sheet. The pedal has a first clipless end extending therefrom. The locking sheet has a second first clipless end extending therefrom opposite to the first clipless end. A clipping space is defined between the first clipless end and the second clipless end. The elastomer has one end abutting against the pedal and the other end abutting against the locking sheet.

Abstract: A bicycle pedal with adjuster includes a pedal and at least one adjuster mounted in the pedal. The pedal has at least one buckling frame pivotally mounted thereon. Each buckling frame has a spindle passing through the pedal and the buckling frame. The at least one buckling frame has at least one elastomer mounted therein. Each adjuster has a head formed on one end thereof and a first threaded portion formed on the other end thereof. Each adjuster has a second threaded portion formed between the first threaded portion and the head. A threaded direction of the first threaded portion is opposite to that of the second threaded portion. A block portion is screwed on the second threaded portion and a position member is screwed on the first threaded portion.

Abstract: A pedal retaining apparatus includes a driving unit adapted to engage with a pedal. The driving unit has a first magnetic unit disposed thereon and a positioning unit corresponding to the driving unit, the positioning unit has a second magnetic unit disposed thereon. The second magnetic unit corresponded to the first magnetic unit. The pedal is magnetically retained in a predetermined position due to a magnetic force between the first magnetic unit and the second magnetic unit; when the pedal rotates relative to the spindle, the magnetic force between the first magnetic unit and the second magnetic unit drives the driving unit to rotatably regain the predetermined position for the pedal to synchronously rotate with the driving unit to regain the predetermined position.
