摘要： A unitary system for an electric-assist bicycle generates signals indicative of power input to a drive system of the bicycle when a rider pedals the bicycle, considering torque applied by the rider, as well as the cadence or speed of the rider's pedaling. Direction of pedaling is also measured using the system. The system utilizes fixed, hard-wired, contactless electronics, namely first and second inductance coils that are non-equally-spaced circumferentially around a first axis, and which generate a first electrical signal indicative of torque based on lateral movement of a conductive or otherwise magnetically permeable rotatable member relative to the coils, and which generate second and third electrical signals indicative of pedaling cadence and direction based on eccentric relative rotational movement of the conductive or otherwise magnetically permeable rotatable member relative to the first and second inductance coils.

摘要： A gearbox may include a drive spindle and several interconnected gear clusters arranged in a housing. A first of the gear clusters is coaxially fastened to the spindle, and has an outboard gear and an inboard gear. The first gear cluster drives a belt to operate one or more of the other gear clusters, and the inboard gear is physically divided into a plurality of segments. A shifting system for the gearbox includes an actuator configured to urge the segments of the inboard gear of the first gear cluster into and out of the plane of the belt, such that a gear ratio of the gearbox is changeable without displacing the belt out of the plane.

摘要： A bicycle includes a bicycle body, a bicycle component, and a battery. The bicycle body has a frame including a down tube, a component mounting portion, and a seat tube. The bicycle component includes a bicycle drive unit. At least a portion of the bicycle component is arranged inside the frame. The battery is mounted on the bicycle to supply the bicycle component with electrical power. The battery is accommodated in the down tube. The frame further includes a first open portion to accommodate the bicycle component in the frame. Both the bicycle component and the battery are partly disposed outside the frame via the first open portion.

摘要： A bicycle internal transmission hub is provided that can be easily coupled to a bicycle body. The bicycle internal transmission hub includes a hub shell, a shifting unit, and an electric actuator. The hub shell defines an accommodation cavity. The shifting unit is located in the accommodation cavity, and is configured to select one speed stage from a plurality of speed stages. The electric actuator is located in the accommodation cavity to drive the shifting unit.

摘要： A directional transmission mechanism, a directional sprocket apparatus using the directional transmission mechanism, and a pedal device using the directional sprocket apparatus are disclosed. The directional transmission mechanism includes a driving shaft, an output shaft, a co-rotating wheel, a reverse-rotating wheel, and a switching mechanism. The co-rotating wheel set drives the output shaft to rotate in a direction that is the same as that of the driving shaft. The reverse-rotating wheel set drives the output shaft to rotate in a direction opposite to that of the driving shaft. The switching mechanism switches the driving shaft to drive the co-rotating wheel set or drive the reverse-rotating wheel set to rotate, so as to enable the output shaft to rotate directionally. The co-rotating wheel set is connected with the driving shaft and the output shaft, and the reverse-rotating wheel set is connected with the driving shaft and the output shaft.

摘要： A bicycle drive system includes a bicycle drive unit and a bicycle battery unit. A first power supply path supplies power from the battery unit to the drive unit. A second power supply path supplies smaller power from the battery unit to the drive unit than the first power supply path. In a case where the drive unit and the battery unit are connected by the first power supply path and the second power supply path, the bicycle drive system is configured to be switched between a first state, in which the battery unit stops supplying power to the drive unit via the first power supply path and supplies power to the drive unit via the second power supply path, and a second state, in which the battery unit supplies power to the drive unit via at least the first power supply path.

摘要： A tiltable vehicle is configured to transform between an autonomous mode and a rideable mode by pivoting the handlebars and steering column of the vehicle about a pitch axis. In the autonomous mode, the steering column is folded back toward the chassis and a tiltable chassis of the vehicle is prevented from tilting. In the rideable mode, the steering column is unfolded and the chassis is free to tilt. In some examples, a tiltable vehicle includes features beneficial for vehicle-sharing, such as parking devices or a basket. These features may be included on any suitable vehicle and are not limited to use on transforming vehicles.

摘要： The present disclosure relates generally to bicycles, in particular, the present disclosure provides systems and devices for converting a standard bicycle into a cargo bicycle using various detachable components. The ability to convert a standard bicycle into a cargo bicycle and back again confers many advantages, including eliminating the need for a separate bicycle for transporting cargo and encouraging the use of bicycles as a mode of transportation.

摘要： A control method comprises at least one detection of activation of the pushing aid. When activation is detected, in the subsequent step a velocity of the electric vehicle and/or a constant starting torque are/is generated by actuation of the electric motor. The generated velocity of the pushing aid as a result of the actuation is dependent on the engaged transmission ratio of the gearshift. In order to adapt the velocity, the control method comprises sensing the current motor rotational speed of the electric motor and sensing the current velocity of the electric bicycle. The engaged transmission ratio is determined as a function of the sensed motor rotational speed and the sensed velocity. The adaptation of the velocity of the electric bicycle occurs in the subsequent step as a result of regulation of the electric motor as a function of the transmission ratio and the maximum velocity, which is not exceeded.
