A navigation signaling system for communicating navigation information of a personal transportation device is provided. The navigation signaling system includes a computer and a navigation system. The computer has at least one display device. The navigation system is coupled to the computer and provides a current position and a course data of the personal transportation device. The computer drives the signal display device to display a directional signal flashing in increasing frequency as a function of proximity of the current position to a turn event in the course data.

A bike includes a frame elongated in a longitudinal direction, a front fork rotatably engaged with a front wheel at a front end of the bike, a rear fork rotatably engaged with a rear wheel at a rear end of the bike, a handlebar supported for rotation at the front end of the frame for steering the bike, and a drive module configured to drive the rear wheel of the bike when operated selectively with power. The frame includes a down tube extending downward and rearward from the front end of the bike and a drive module enclosure formed at a second end of the down tube. The drive module enclosure defines a drive module receptacle that is open along the longitudinal direction of the bike. The drive module receptacle is sized to receive the drive module along the longitudinal direction of the bike.

A vehicle includes an upper frame, a lower frame, a front frame, a rear frame, a pair of rear wheels, a drive motor to drive the pair of rear wheels, a battery supported by the upper frame and the lower frame to supply electric power to the drive motor, a straddled seat at a higher position than the drive motor, and a bar handle at a higher position than the straddled seat. The battery includes a battery lower portion and a battery upper portion. The battery upper portion includes a projection that overhangs in at least a horizontal direction with respect to the battery lower portion. At least a portion of the drive motor is below or directly below the projection.

Systems and methods for mitigating wear of electric vehicles are provided. A method of operating an electric powersport vehicle includes receiving an accelerator command and driving an electric motor of the vehicle based on whether or not the accelerator command is accompanied by a braking command. When the accelerator command exists at a same time as the braking command, the output of the electric motor is limited to a lower output torque value than when the accelerator command exists at a different time as the braking command.

A vehicle includes upper frames, lower frames, a front frame, a rear frame, a pair of front wheels, a pair of rear wheels, a bar handle to steer the pair of front wheels, a drive motor to drive the pair of rear wheels, a battery to supply electric power to the drive motor, and a straddled seat provided at a higher position than the drive motor. The drive motor and the battery are located in a region surrounded by the upper frames, the lower frames, the front frame, and the rear frame in a side view of the vehicle.

A vehicle having an electric drivetrain, e.g., an electric motorcycle, includes a handlebar and switchgear(s) mounted on the handlebar. Vibration generation device(s) are provided in the switchgear(s) and transmit vibrations to the handlebar via the switchgear. The vibrations may be sensed by the driver or operator of the vehicle and provide to the driver or operator of the vehicle feedback or other information relating to the vehicle or its operation.

A fuel filling device of a motorcycle can receive a high pressure gas only when it is ensured that the motorcycle is in a stable position. The device includes a fuel tank that stores and/or supplies a high pressure gas and is mounted on the motorcycle, a filling port through which the high pressure gas is fed to the fuel tank, a center stand that swings between a raised position in which the center stand supports the motorcycle in an upright position and a retracted position, a stand sensor that senses that the center stand is in the raised position, and a fuel filling valve provided between the fuel tank and the filling port and allowing a flow of the high pressure gas between the fuel tank and the filling port if the stand sensor senses that the center stand is in the raised position.

A foldable electric scooter and a manufacture method of the same. The foldable electric scooter includes a main body assembly, a front fork assembly located at the front end of the main body assembly, a rear fork assembly located at the rear end of the main body assembly, a telescoping plate assembly located on top of the front fork assembly and a handlebar assembly located on top of the telescoping plate assembly. The foldable electric scooter has a double headset design that increases a rake angle for more steering stability while still keeping the steering upright for an upright holding of the handlebars. The foldable electric scooter is manufactured by stamping of flat plate material.

An electric motorcycle includes a housing for housing an electric motor and/or a transmission. The housing is positioned at the center of the electric motorcycle in a front view. An internal cooling device and/or an electronic component and two cooling elements extend outward from opposite sides of the housing. Exterior cooling ribs are arranged on the cooling elements. The cooling ribs extend in the longitudinal direction of the electric motorcycle, such that the cooling elements and the cooling ribs are directly in contact with the air surrounding the electric motorcycle. The cooling device and/or the electronic component is, at least in portions, housed in and thermally connected to at least one of the cooling elements.

A method for operating a control unit of a light-weight vehicle, especially of a pedal electric cycle or of an electric kick scooter. The method includes: receiving at least one sensor information associated with a sensor of the vehicle; and transmitting, via a communication channel between the control unit and a personal mobile terminal, the at least one sensor information and/or at least an information based thereon.
