A brake pedal structure for a saddled vehicle is configured to include a master cylinder supplying hydraulic pressure to a brake caliper of the saddled vehicle and a brake pedal connected to the master cylinder through a connection mechanism. The connection mechanism includes a holder, an arm, and a connection pin. The holder presses the master cylinder, the arm is fixed to the brake pedal, and the connection pin pivotally supports the holder and the arm so as to be swingable against each other. The connection pin includes a small diameter shaft, a large diameter shaft, and an arm support shaft. The small diameter shaft and the large diameter shaft are pivotally supported by the holder and have a circular cross section. The arm support shaft is pivotally supported by the arm and has a circular cross section. The arm support shaft is eccentric with respect to the small diameter shaft and the large diameter shaft.

The saddle-ride vehicle includes: a vehicle body frame; a hydraulic braking device that brakes a rear wheel; and a reservoir tank that stores a brake fluid of the braking device, the reservoir tank being supported on the vehicle body frame via a bracket, the reservoir tank being covered from an outside in a vehicle width direction by the vehicle body frame.

An electric bicycle includes a frame that has a concave or arc shape. The bicycle also includes two wheels—a front wheel and a rear wheel, with each wheel being connected with an end portion of the frame. A battery-powered electric motor may be connected with the rear wheel to drive the rear wheel and propel the bicycle forward. The battery may be rechargeable. The speed of the bicycle may be controlled by the operator moving a lever with one of their feet. A rotatable knob located on the frame may be used as a cruise control speed setting device. The electric bicycle may be steered by the operator using their feet resting on a pair of foot pegs that are attached to or connected with the front wheel. The electric bicycle may include a regenerative braking system or a friction braking system.

A master cylinder for a brake. The master cylinder includes a cylinder main body having a hydraulic pressure chamber, a reservoir tank having a storage chamber, and a separator that is provided in the reservoir tank to divide a space in the storage chamber of the reservoir tank into an upper region and a lower region. A hydraulic fluid is storable in the hydraulic pressure chamber, and is storable in the storage chamber for thereby replenishing the hydraulic pressure chamber. The hydraulic fluid is circulatable between the upper region and the lower region, such that a liquid surface of the hydraulic fluid is in the upper region. The separator has a lower surface in the lower region. The lower surface has an inner portion, and an inclined portion that surrounds the inner portion and that is inclined outwardly and upwardly with respect to the inner portion.

The present invention provides a smart mobile vehicle comprising a vehicle body, a chassis, driving wheels, a battery module, a plurality of motors and a vehicle control unit. The chassis has a suspension system, a brake system and a steering system. The two driving wheels are composed of a plurality of circular units, and the driving wheels are embedded in two-wheel frames on two sides of the vehicle body. The battery module provides the smart mobile vehicle with driving power. The plurality of motors disposed between the two circular units or on a surface of any one of the circular units; wherein the motors are electrically connected to the battery module, and the torque and directional outputs of the motors is used to drive the rotation of the two driving wheels. The vehicle control unit is electrically connected to the motors and the battery module to transmit a monitoring signal.

This invention is an electric unicycle. It is an improvement of a unicycle and a self-balancing electric unicycle. It comprises one wheel (1B), brushless DC motor (1C), operating-pedal (1D), seat (2A), pneumatic springs (2B) for shock absorb, mainboard (1F), lithium-ion battery pack (1G), telescopic handle (1I), emergency brake footboard (1J), casing (1H). The emergency brake footboard (1J) can be easily mounted and unmounted and folded. While in using, the user generally rides on the seat, swings their foot, to adjust the depression angle of the operating-pedal (1D), to control the wheel rotation, rather than by an electric gyro. Thus, this invention is easy to operate, easy to learn, easy to use, flexible, portable, zero emission, great trafficability. It will become the main short-distance means of transportation for cities and villages, and even can be used in poor road conditions, such as field exploration and forest patrol.
