Provided are a self-balancing scooter and a control method thereof, and a kart powered by the same. The self-balancing scooter includes two scooter bodies on which foot boards and motorized wheels are disposed, and a rotating shaft device, where the rotating shaft device includes a rotating shaft, two axle seats, and a torsion limiting mechanism. The torsion limiting mechanism controls a rotation angle by the fit between a limiting portion on the rotating shaft and a fitting portion on one axle seat. The present disclosure realizes torsion limit by directly using the rotating shaft and the axle seats without the use of an additional element (for example, a limiting shaft), thus simplifying the structure of the rotating shaft device and facilitating assembly.

A control system in accordance for a human-powered vehicle comprises a brake device configured to brake a wheel, a brake operating device operated to actuate the brake device, a first communication path configured to communicate a first actuation signal between the brake device and the brake operating device, and a second communication path configured to communicate a second actuation signal between the brake device and the brake operating device. The second communication path differs from the first communication path.

A motorcycle brake pedal lever includes a rod connected to a motorcycle and a base is connected to the rod. The base includes a bore. A pivotal member includes a first pivot and a second pivot extending toward different directions. The first pivot is pivotably connected to the bore of the base so that the pivotal member is pivotable about the first pivot. A peg includes a space formed therein, and the second pivot of the pivotal member is pivotably engaged with the space by a pin so that the peg is pivotable about pin and the second pivot. Multiple torsion springs are respectively mounted to the first and second. The torsion springs respectively contact the pivotal member, the base and the peg. The peg is returned relative to the pivotal member, and the pivotal member is returned relative to the base by the torsion springs.

The invention has a purpose of obtaining a brake hydraulic pressure controller capable of securing durability with a simple configuration and a motorcycle brake system. The brake hydraulic pressure controller is a hydraulic pressure controller for a vehicle brake system and includes: a base body that is formed with a channel filled with a brake fluid therein; a hydraulic pressure regulation valve that has a plunger and opens/closes the channel by translatory movement of said plunger; a drive coil that has a hollow section, is vertically provided in the base body in a state where one end of the plunger is inserted in said hollow section, and causes the translatory movement of the plunger to drive the hydraulic pressure regulation valve; and a coil casing that accommodates the drive coil. The coil casing includes a wall that covers at least a part of an apex of the vertically-provided drive coil, and the drive coil is pressed toward the base body by a projection formed in the wall.

To achieve a brake hydraulic pressure control system which makes it possible to suppress an increase of the manufacturing cost as compared to existing brake hydraulic pressure control systems which ground a control board using a coil spring. A brake hydraulic pressure control system according to the present invention includes: a metallic substrate (80) in which a flow channel for brake fluid is formed; and a control board (76) of a hydraulic pressure control mechanism for the brake fluid provided in the flow channel. The brake hydraulic pressure control system according to the present invention further includes at least one conductive plate spring (90) which is provided between the control board (76) and a component that is electrically connected to the substrate (80). The free length of the plate spring (90) is longer than the distance between the control board (76) and the component, and the plate spring (90) has a first end part (93) connected to the control board (76) and a second end part (94) connected to the component.

The present disclosure relates to a foldable vehicle and to several exemplary components thereof, which may comprise a hinge cassette and a rear wheel brake assembly among other components. In some examples, the vehicle has a folded configuration and an unfolded configuration, where in the folded configuration, the at least one rear wheel nests within the at least one opening.
