A system, generally for use with light personal vehicles such as bicycles or e-bikes, for enabling a vehicle trailer and a tow bar to be interconnected in either a braking configuration or a non-braking configuration, is described. Also described is a braking kit for interconnecting a tow bar and a vehicle trailer in a braking configuration, wherein the vehicle trailer comprises a connection interface dimensioned to be connected with an end of the tow bar in a non-braking configuration. When the tow bar and the trailer are interconnected in the braking configuration, at least a threshold amount of rearward force imparted via the tow bar during vehicle braking causes the actuation of at least one brake associated with the trailer wheels. The same tow bar can be used in either braking or non-braking configuration.

A vehicle includes a first sensor, a second sensor, an engine, a fuel supplying device, and a control device. The control device includes a first sensor detecting unit, a second sensor detecting unit, a vehicle status detecting unit, and a control unit. The control unit is switchable among a regular state, a start-stop enabling state, and an idling-stop state. The control unit switches into the start-stop enabling state from the regular state once the control unit determines that the first sensor and the second sensor are both triggered. The control unit further switches into the idling-stop state and controls the fuel supplying device to stop supplying fuel once the control unit determines that the vehicle status meets an idling-stop condition.

A control device is provided for a human-powered vehicle. The control device includes an electronic controller that is configured to control a motor that assists in propulsion of the human-powered vehicle. The electronic controller is configured to control the motor in accordance with a pitch angle of the human-powered vehicle and information related to a user load applied by a user to the human-powered vehicle in a negative direction with respect to a propulsion direction of the human-powered vehicle.

A control device is provided for controlling a human-powered vehicle. The control device includes an electronic controller configured to control a motor that applies a propulsion force to the human-powered vehicle. In a case where a predetermined condition is satisfied, the electronic controller is configured to increase at least one of an assist level of the motor, a maximum value of an output of the motor, and the output of the motor. The predetermined condition includes a first condition in which deceleration of the human-powered vehicle in a traveling direction of the human-powered vehicle is greater than or equal to a first threshold value.

A vehicle suspension pre-load management system is disclosed. At least one suspension component, such as a motorcycle shock absorber, has an expandable chamber that with increased volume of a nearly incompressible fluid increases the suspensions pre-load. In one embodiment the system utilizes a controller, a pressure sensor, a pump, and a number of solenoids in a manifold block to allow a user to set a desired pre-load level. In another embodiment the controller monitors the pressure of the chamber and maintains a desired pre-load setting. In yet another embodiment, the controller identifies a hard braking event such that would cause a brake dive and increases the pre-load to counter act the dive.
