Abstract: A piezoelectric energy hunting device and a voltage signal application system thereof are disclosed. The piezoelectric energy hunting device includes a plurality of curved piezoelectric elements, a plurality of rigid foams, and a flexible foam structure. The plurality of curved piezoelectric elements are arranged side by side with one another, wherein each curved piezoelectric element is attached to one of the rigid foams. The flexible foam structure includes a top foam and a bottom foam covering the outer surface of the plurality of curved piezoelectric elements and the plurality of rigid foams; when the flexible foam structure is compressed, the plurality of curved piezoelectric elements are simultaneously deformed, thereby generating a voltage signal. When the flexible foam structure is not compressed, the flexible foam structure and the plurality of rigid foams provide an elastic force to restore the plurality of curved piezoelectric elements.

Abstract: The present disclosure describes various aspects of crank-based lighting, which may improve visibility of pedal-based vehicles or conveyances. In some aspects, a light generating apparatus includes a crank interface and lighting system. The crank interface may facilitate mounting of the apparatus to a crank (or crankarm) of a bicycle or other pedal-based vehicle. The lighting system may generate or emit light based on information indicating an angle, movement, and/or position of the crank, such as to cause light emission to emulate or project leg movement of a rider.

Abstract: A clipless bicycle pedal auxiliary tool includes two cramp bodies, each cramp body includes a pivot part, a holding section and a clamping section, the two pivot parts are pivoted with each other, and the holding sections and the clamping sections are disposed on two sides of the pivot parts, respectively. Each clamping section includes a clamping pin and a pushing pin protruded thereon. The two holding sections can be operated to pivotally swing the two clamping section relative to each other, and make the two clamping pins and the two pushing pins move close to and away from each other, so that the two clamping pins can clamp the two inner sides of the clamping fastener of the clipless bicycle pedal, and the two pushing pins push the two outer sides of the clamping fastener to form a force pivot.

Abstract: Conventional bicycle pedals and cleats are provided in a myriad of specific designs. Cleat designs offer varying amounts of relative movement between the pedal and cleat to accommodate the needs of cyclists. However there exists room for improvement in existing designs for a cleat which improves a cyclist's pedalling technique and pedalling efficiency, which in turn reduces the likelihood of knee and other injuries, whilst at the same time reducing the rate of cleat wear. The present invention provides a cycling footwear cleat for connection to a receiving portion of a pedal, the pedal having a mounting shaft to which the receiving portion of the pedal is rotatably mounted, the cleat including: a mount for mounting the cleat to an underside of cycling footwear; an attachment portion for receipt by the receiving portion of the pedal; and a resilient member provided between the attachment portion and the receiving portion when the pedal is attached to the cleat, wherein the resilient member resists movement of the attachment portion relative to the receiving portion. The provision of a resilient member improves a cyclist's pedalling efficiency, as well as allowing for variable float of the cleat within the pedal as and when required. It also improves the control of pedal float, since the cleat is less likely to move in an uncontrolled motion relative to the pedal.

Abstract: The cleat of the present invention integrated with a shoe has a dual structure of a movable upper part and a fixed lower part, so that an effect is achieved in that a rider moves a pedal shaft on the flat ground and the inclined ground by simply moving the shoe. It is convenient to switch between a first stage mode and a second stage mode on the flat ground by simply changing the location of a foot while riding the bicycle. Records can be renewed significantly efficiently by appropriately distributing power according to the terrain without wasting time during a game.

Abstract: A bicycle shoe cleat includes a first slot defined through a front portion of the bicycle shoe cleat, and two second slots defined through a rear portion of the bicycle shoe cleat. Bolts extend the first and second slots, and are connected to the outsole of a racing bicycle shoe. A protrusion extends from one of two surfaces of the rear portion and has a convex and curved outer surface. A stepped portion is formed between the protrusion and the rear portion. Two bores are defined through the protrusion and the bicycle shoe cleat. Two fixing bolts extend through an engaging member and are connected to the two bores. The bicycle shoe cleat and the engaging member are installed to a racing bicycle shoe and can be clipped to clipless pedals of mounting bikes.

Abstract: A bicycle includes a frame and a bottom bracket inserted in a housing made in the frame, and has a column, on the head portion of which a saddle is inserted; a headstock that supports a handlebar; a connecting longitudinal member of a bottom portion of the column with the headstock; and a first reinforcing longitudinal member mechanically connected at a first end thereof to the headstock and at a second end thereof to the column. The connecting longitudinal member has, in a first portion close to the junction with the column, a loading section shaped to support the loading of objects or other material, and the housing of the bottom bracket is at a section of the intermediate column between the head portion and the bottom portion.
