This electrical self-balancing scooter has the advantages of being easy to assemble and disassemble as well as being comfortable to ride.

A control device for an electric bicycle includes a motor, a battery, a micro controller, an acceleration detector and a transmitter electrically connected to each other. A physical-condition monitor detects the rider's heart rate signal. A computer calculates an electric power consumption value from the micro controller, an acceleration value from the acceleration detector, and the heart rate signal to create a motor output adjustment signal which is created according to the practical conditions of the rider. The motor output adjustment signal is sent to the micro controller to adjust the output of the battery to the motor and the assistance force to the bicycle.

An apparatus controller for prompting a rider to be positioned on a vehicle in such a manner as to reduce lateral instability due to lateral acceleration of the vehicle. The apparatus has an input for receiving specification from the rider of a desired direction of travel, and indicating means for reflecting to the rider a propitious instantaneous body orientation to enhance stability in the face of lateral acceleration. The indicating may include a handlebar that is pivotable with respect to the vehicle and that is driven in response to vehicle turning.

An automatic tilting vehicle includes left and right wheels rotatably supported by carriers, a vehicle tilting device, and a control unit. The vehicle tilting device includes a swing member swinging about a swing axis, an actuator that swings the swing member, a pair of tie rods pivotally connected to the swing member and the carriers. The control unit controls the actuator so that the tilt angle of the vehicle conforms to a target tilt angle and determines that the vehicle tilting device is abnormal when a relationship between the swing angular velocity of the swing member and the tilt angular velocity of the vehicle deviates from an allowable range.

A method of operating a vehicle at different altitudes. The vehicle has an engine, a throttle valve and a throttle operator. A continuously variable transmission has a driving pulley connected to the engine, a driven pulley, and a belt operatively connecting therebetween. A ground engaging member is operatively connected to the driven pulley. A piston is connected to the driving pulley. A control unit controls actuation of the piston and the piston force. The method includes determining an altitude and/or an atmospheric pressure, a driven pulley speed, and at least one of the throttle operator position and the throttle valve position. The piston is selectively actuated based on the altitude and/or the atmospheric pressure. The piston force is controlled based on the driven pulley speed, and at least one of: the throttle operator position and the throttle valve position. Vehicles and other methods of operation thereof are also disclosed.

The yoke module is including wherein an elongated USB power cable, one or more yoke module sections accommodating access for the USB power cable and wire connectors to be threaded through one or more slotted openings and to exit out the top yoke module section, a first connection method to connect with the drive motor's lead cable harness directly to the USB power cable, a method to conceal and protect the drive motor's lead cable harness and the USB power cable by means of a coupling enclosure and yoke sleeve enclosure achieved through the yoke module's fabrication process. The yoke module also comprises a method for USB power cable to provide electricity power to drive a motorized wheel. The yoke module system comprises a second connection method for the yoke module to plug into auxiliary components including; a battery, a computer control system, and sensors for motion stability.

A system for dynamic distribution of bicycle lighting including a plurality of light sources coupled to and under operation of a controller. The controller controls power distributed to the light sources and provides dynamic illumination of the light sources according to bicycle operating condition data, regarding the speed, angle of incline, angle of descent and geographic and terrain conditions in which the bicycle is operated.

A bicycle control device is provided that allows the rider to ride a bicycle comfortably. A bicycle electric assist unit is provided that includes the bicycle control device. The bicycle control device includes an electronic controller that controls an operational state of a bicycle component based on at least an operational state of the bicycle electric assist unit. The bicycle component includes at least one of an electric suspension and an electric adjustable seatpost.

A control device is used with a human-powered vehicle including a vehicle component and at least first and second detectors. The first detector detects first information of the human-powered vehicle and the second detector detects second information of the human-powered vehicle. The control device includes an electronic controller that controls the vehicle component in accordance with outputs of the first detector and the second detector. The electronic controller controls the vehicle component in accordance with the output of the second detector where the output of the first detector is not in the first state and the output of the second detector is in the second state, and controls the vehicle component in accordance with the output of the first detector where the output of the first detector is in the first state and the output of the second detector is not in the second state.
