A bicycle power meter includes a strain gauge, a signal processing unit, a processor, and a signal transmitter. The strain gauge is disposed on at least one of an outer peripheral wall and an inner peripheral wall of a stem of a bicycle. The signal processing unit connected to the strain gauge by signal correspondingly outputs an electrical signal based on a deformation of the stem detected by the strain gauge. The processor connected to the signal processing unit by signal receives the electrical signal sent by the signal processing unit and calculates a measuring value based on the electrical signal and sends the measuring value in an output signal. The signal transmitter connected to the processor by signal receives the output signal sent by the processor and converts the output signal to a wired or wireless signal and sends the wired or wireless signal to a terminal device.

A position sensor according to the present invention includes: a magnet configured to move together with a moving body and generate a first magnetic flux along a specific movement direction of the moving body and a second magnetic flux along the opposite direction to the specific movement direction of the moving body; and a sensor configured to detect the direction of the first magnetic flux and the direction of the second magnetic flux. The magnet is configured by at least one magnet having at least two pairs of magnetic poles to be paired formed thereon.

A saddle riding vehicle includes a steering handlebar, a pair of left and right handle posts that supports the handlebar, and a stay that supports an electric part. In the saddle riding vehicle, the stay is supported by the handle posts, the electric part includes a first electric part and a second electric part, and the second electric part is disposed at least at a position between the left and right handle posts in a vehicle front view.

An electrical switch device includes an electrical switch unit, a wireless communicator, a power source, an electrical cable, and a connecting part. The electrical switch unit is at least partly disposed outside of a handlebar. The wireless communicator is inserted to an internal space of the handlebar. The power source and the wireless communicator are separated away from the electrical switch unit and arranged at different positions from the electrical switch unit. The electrical cable is configured to electrically connect the electrical switch unit to the wireless communicator and the power supply. The connecting part is electrically connected to the electrical cable. The connecting part is configured to electrically and detachably connect the electrical switch unit to the wireless communicator and the power supply.

A device includes a magnet and a magnetic field sensor configured to sense a magnetic field of the magnet. The magnet and the magnetic field sensor are arranged to be movable relative to each other. A relative movement between the magnet and the magnetic field sensor is based on a movement of a throttle controller of a vehicle. A power provided by a motor of the vehicle correlates to a position of the magnet relative to the magnetic field sensor as sensed by the magnetic field sensor.

An operating device for a bicycle is disclosed. The operating device includes a display ring and a coaxially arranged operating ring arranged to rotate relative to the display ring. The display ring includes a display for displaying information and a first magnetic element that cooperates with a second magnetic element arranged on or in the operating ring. In a first position of the operating ring relative to the display ring, the first magnetic element is proximate to the second magnetic element, and if the operating ring is rotated away from the first position, the first magnetic element and the second element magnetically cooperate to bias the operating ring back to the first position. The display ring further includes a sensor that receives a signal when in proximity of a signal providing element.

The present disclosure provides a scooter. The scooter includes a scooter body, a driving portion, a wheel portion, a photographing portion and a control portion; the driving portion is connected with the scooter body; at least part of wheel portion is movably connected with the driving portion; the photographing portion is connected with the scooter body, so that an environment around the scooter body is photographed through the photographing portion; the control portion is connected with the scooter body; the control portion is electrically connected with the photographing portion and the wheel portion; and the control portion controls the driving portion according to a signal collected by the photographing portion, thereby driving the at least part of wheel portion to drive the scooter body to move and avoid an obstacle.
