Bicycle including a frame with a fork, the fork having dropouts between which a wheel axle is mounted. The wheel axle includes a sensor and/or an electric component arranged to be connected to a control element. A detachable electric connection is provided between the sensor and/or electric component and the control element. The detachable electric connection includes a short range wireless connection.

A straddled vehicle including a vehicle body frame having a head pipe extending downward and forward, a steering shaft supported by the head pipe to be rotatable left and right, a front fork connected to the steering shaft, a front fender supported by the front fork, a front cover of which a portion is arranged further forward than the head pipe, and a radar supported by the vehicle body frame and arranged further forward than the head pipe. The front cover includes a front end, and a lower edge extending leftward or rightward from the front end in a front view, at least a portion of the lower edge being located at or below the front end. At least a portion of the radar is arranged further downward than the front end of the front cover, further downward than the lower edge, and further upward than the front fender.

A sensor wheel for a human-powered vehicle comprises a wheel body and an attachment part. The wheel body is configured to be rotatable relative to a vehicle body of the human-powered vehicle about a rotational axis along with a rotational hub of the human-powered vehicle. The wheel body includes a plurality of openings spaced apart from each other in a circumferential direction with respect to the rotational axis. The attachment part is configured to be operatively coupled to the rotational hub. At least one opening of the plurality of openings has a radial length defined radially with respect to the rotational axis. The radial length is equal to or larger than 8 mm.

A measurement of the rotation speed of an object is made using a time-of-flight sensor configured to detect a passing of one or more of elements of the object through a given position. The time-of-flight sensor is further mounted on a one-person vehicle configured to protect the one-person vehicle against collisions through the making a time-of-flight measurement of a relative speed between the one-person vehicle and an obstacle.

A bicycle speed sensor is provided on a bicycle. The bicycle includes a chain stay, a rear wheel, a brake disk and a positioning member. The rear wheel includes a hub and the brake disk includes a center hole disposed for the hub to pass through. The positioning member passes through the chain stay, the center hole and the hub so that the rear wheel and the brake disk are positioned on the chain stay. The bicycle speed sensor includes a signal transmitter and a signal sensor. The signal transmitter is configured to transmit a signal and disposed on the brake disk. The signal sensor receives the signal from the signal transmitter and is disposed on the chain stay. By fixedly positioning the signal transmitter and the signal sensor at the brake disk and a default position of and the chain stay respectively, displacements of sensor components is prevented to provide reliable sensing data.

A wireless apparatus of an electric motorcycle is assembled to a body of the electric motorcycle and has a receiver, a front wheel tire pressure sensor, and a rear tire pressure detector. The receiver is disposed at and extends out from one of a left side and a right side of a frame of the body. The front wheel tire pressure sensor and the rear wheel tire pressure sensor are disposed at a front wheel and a rear wheel of the body, respectively, and communicate with the receiver via wireless communications. Wherein, the receiver is located aside to prevent shielding effect caused by a battery of the body, thereby enhancing signal quality to allow the receiver to stably receive signals from the front wheel tire pressure sensor and the rear wheel tire pressure sensor.

A suspension assembly for a cycle includes a link and an indicator having a central opening. The indicator includes a first retention feature. A pivot assembly is disposed in the link. The pivot assembly includes a second retention feature. The first retention feature and the second retention feature cooperate to axially retain the indicator on the pivot assembly while allowing rotational movement between the indicator and the pivot assembly when a force threshold is exceeded.
