    Abstract: A coaxial mid-drive power device of a bicycle includes a reducing structure and a hollow shaft motor engaged with the reducing structure that are disposed in a motor base. An output end of the reducing structure is operatively coupled with a one-way bearing bracket with a sprocket base via a one-way bearing. A crank spindle engaged with the one-way bearing bracket through another one-way bearing penetrates through the motor base. The two one-way bearings respectively have opposite rotation directions and are respectively located on different sides, i.e., an inside and an outside, of the one-way bearing bracket. A strain gauge disposed on the crank spindle is electrically connected to an annular conductive rail assembly engaged with the crank spindle and an elastic sheet assembly on a control circuit board in the motor base, hence the strain gauge could directly obtain a change in a torque of the crank spindle.

    Abstract: A pedal for bicycles includes a pedal pin that extends along a reference axis and has a first axial end structured to be coupled to a pedal crank of a bicycle and a second axial end opposite to the first end and a pedal body that comprises a hub coupled in a freely rotatable manner to the pedal pin so as to be able to rotate around the reference axis. On the pedal pin there are at least two inner chambers having a circular section and extending along the reference axis coaxial thereto, a sensor circuit coupled to the pedal pin, an electronic circuit configured to determine the mechanical deformation of the pedal pin, and an electric storage device arranged in an inner chamber.

    Abstract: A power switching structure includes an input shaft, a detection shaft sleeve fit over the input shaft, an assisting power assembly, and an output assembly selectively drivable by the input shaft and the assisting power assembly. The output assembly includes first and transmission sleeves rotatably mounted to the input shaft. The assisting power assembly includes a power member rotatably mounted to the second transmission sleeve. A one-way bearing is arranged between the first and second transmission sleeves and the power member. An output member is mounted on the second transmission sleeve. A micro-motion static frictional force is induced between the first and second transmission sleeves and the input shaft to allow the detection shaft sleeve to directly and accurately measure a torque value of the input shaft. The one-way bearing arranged between the first and second transmission sleeves and the power member allows for selection among sources of power.

    Abstract: A bicycle torque detector includes a crank shaft formed with a first ring section and a second ring section; the first ring section serving for receiving a deformation sleeve accommodating ring and a deformable sleeve; the second ring section serving for receiving a circuit board ring; a circular casing serving to enclose all the crank shaft, the elastic ring, the sleeve, and the circuit board ring; wherein the first ring section of the crank shaft is formed with at least one resisting portion; the deformable sleeve has at least one resisting portion; the resisting portion of the crank shaft resists against one end of the deformation sleeve accommodating ring; another end of the deformation sleeve accommodating ring resists against the resisting portions of the deformable sleeve. A rear end of the deformable sleeve is engaged to a chain sleeve. The deformation sleeve accommodating ring is adhesive with sensing sheet.

    Abstract: A cycle driving device has a torque sensor, a crankset axle or a hub connected to a plate by a coupling, and a driving and measuring member having a first section secured in rotation with the crankset axle or hub, and a second section connected to the plate. A magnetic field source is supported by one of the sections. The coupling member incorporates a torque detection device. The first and second sections cooperate through an elastically deformable element. The torque detection device comprises a fixed magneto-sensitive element that measures a magnetic field according to the relative angular position of the first and second sections, and is capable of converting the magnetic field into an electrical signal. The magnetic field measurement is performed at a single axial position in the periphery of the first and second sections independently of the rotation of the crankset axle or hub.
