This vehicle transmission system includes a transmission (21) in which a gear is shifted by an operation of a driver of a vehicle (1), a clutch device (26) that is disposed in a motion transfer path between the transmission (21) and an engine (13) of the vehicle (1), and is disconnected and connected by an action of a clutch actuator (50), and a clutch control unit (61) that is configured to control disconnection and connection of the clutch device (26) by the clutch actuator (50). In a case where the vehicle (1) is started with a gear position of the transmission (21) located at or above a gear that is set in advance, and a vehicle speed (V) is less than or no higher than a set value (v2) that is set in advance, the clutch control unit (61) transitions to clutch capacity-limiting control in which a clutch capacity is reduced below that during normal clutch control.

A foldable rotary arm structure and device for a bicycle. The foldable rotary arm structure includes a rotary wheel and a rotary arm. The rotary wheel is coaxial with a transverse tube or surrounds the transverse tube. The rotary arm is in steering connection with the rotary wheel or a supporting base, such that the rotary arm is attached to the transverse tube when folded, thereby reducing the space of the transverse tube occupied in a radial direction. A flywheel for use in a balancing device of a bicycle or a motor-assisted bicycle or an amusement device is provided. In the rotary arm, individual batteries or multistage batteries are arranged in a single layer in the radial direction and are stacked in multiple stages in the axial direction. When the rotary arm is unfolded and rotated, the angular momentum is increased or the torque is balanced.

A bicycle safety enhancement device includes an elongated member having a distal portion mountable to a bicycle handlebar. A proximity sensor is coupled to a proximal portion of the elongated member and is arranged so that when the elongated member is mounted to a handlebar of a bicycle being ridden by a cyclist, the ultrasonic sensor detects objects adjacent to and/or behind the bicycle and which come within a prescribed distance of the bicycle. An illumination source is coupled to the proximal portion of the elongated member. The illumination source provides a visible warning signal directed toward the detected object when the elongated member is mounted to the handlebar of the bicycle. A camera is coupled to the proximal portion of the elongated member and is arranged to capture images of the detected object as the detected object passes in front of the bicycle being ridden by the cyclist.

By means of the system described, the use of eddy current generators on vehicles, especially bicycles, can be simplified by easier integration into standardized components such as brake pads, making them more suitable for everyday use. The problem of overcoming the magnetic holding forces at low speeds is essential for cyclists, as these would otherwise rule out the use of such systems in everyday traffic due to the lack of power generation when starting off at low speed. The integration into brake pads provides a significant advantage, as a new functionality is achieved without the need for additional components. The claimed additional functions for signalling contribute to increased traffic safety, especially for two-wheel traffic.
