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.

Motor control systems and methods for micromobility transit vehicles are provided. A micromobility transit vehicle may include an electric motor configured to drive a rotation of a wheel. The electric motor may include a plurality of windings and a plurality of switching circuits. The switching circuits may be configured to selectively direct current from a power supply through the windings to generate a torque by the electric motor to drive the rotation of the wheel in response to associated control signals. The switching circuits may be configured to passively bypass the windings in response to an interruption of the control signals. Depletion of the power supply may result in the interruption of the control signals.

The present invention relates to an upright single-wheeled electromotive apparatus, the upright single-wheeled electromotive apparatus according to an embodiment of the present invention comprising: a handle part having a speed-controlling means on one side; an upper frame connected to the handle part and extending lengthwise, and accommodating a battery therein; a brake connected to the upper frame; a drive unit connected to the brake, and rotates a roller; a pair of lower frames for supporting the upper frame while fixing the brake and drive unit on the inner side thereof; a wheel, positioned between the pair of lower frames, which, when the upper frame moves in one direction with respect to a reference position, stops rotating due to the brake coming into contact with the outer surface of the wheel, and when the upper frame moves in the other direction with respect to the reference position, rotates due to the roller of the drive unit coming into contact with the outer surface of the wheel; and a control unit for varying the rotational speed of the drive unit by means of the speed-controlling means.

A sprocket support body comprises at least ten external spline teeth including a plurality of external-spline driving surfaces. The plurality of external-spline driving surfaces each includes a radially outermost edge, a radially innermost edge, and a radial length. A total of the radial lengths of the plurality of external-spline driving surfaces is equal to or larger than 7 mm. At least one external-spline driving surface has a first external-spline-surface angle. The first external-spline-surface angle ranges from 0 degree to 10 degrees. One tooth of the at least ten external spline teeth having a first circumferential spline size. The other teeth of the at least ten external spline teeth each have a second circumferential spline size that is smaller than the first circumferential spline size. A total number of the other teeth of the at least ten external spline teeth being equal to or larger than nine.

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.
