A transmission structure of electric clutchless motorcycle includes an electric motor, a variable speed gear set, a variable speed gear box and a gear position sensing unit. The arrangement of the gear position sensing unit is so configured that the transmission structure of electric clutchless motorcycle mechanism not only maintains the inertial energy recharge of the electric motor to increase the endurance of the vehicle, but also allows the driver to accurately control the speed control knob when switching gears, and furthermore can increase the automatic gear shift function of the electric gear shift design.

A bicycle operating device comprises a base member and an operating member. The base member includes a hydraulic-unit attachment part to which a hydraulic unit is to be attached, and a first end portion to be mounted to a handlebar. The operating member is movably coupled to the base member. The operating member includes a first wire attachment part to which a first wire end of a control wire is to be attached.

The present invention is an electronic gear-shifting device of an electric motorcycle for simulating gear shifting power output, including an electronic shift unit, an electronic clutch unit and a throttle position sensor, and correspondingly outputting a shift signal, a clutch signal and a throttle position signal according to the operation of the rider. A vehicle controller receives the shift signal, the clutch signal and the throttle position signal to determine a target gear position of the electric motorcycle. The vehicle controller looks up a motor torque command according to the target gear position table and outputs the motor torque command to a motor controller, so that the motor controller controls an electric motor of electric motorcycle. Therefore, the electric motorcycle simulates the power performance of a general motorcycle without adding a physical clutch, a gearbox and other shifting mechanisms.

Methods and systems for activating electric vehicles are provided. One method includes, in response to a first command to activate the vehicle, transitioning the vehicle from an inactive state to a wake state where a controller of the vehicle is activated and the vehicle is prevented from being propelled by an electric motor of the vehicle. The method also includes, in response to receiving a second command to activate the vehicle after receiving the first command, transitioning the vehicle from the wake state to a ready state where the vehicle is permitted to be propelled by the electric motor.

An electric motorcycle includes a battery pack, a controller and a charging device arranged in sequence along the height direction of the frame. The battery pack and the charging device are positioned on the frame adjacent to the front wheel. The rear suspension comprises a rear fork and a shock absorber connected to the frame by a shaft, the rear fork is connected to the rear wheel, and the electric motor is arranged on the rear fork. The center of gravity of the electric motorcycle is lower. The electric motorcycle can run stably even at a speed of 120 km/h.

An optical sensor disposition structure of a saddle riding vehicle includes an optical sensor, left and right handle bar grips installed on both side portions of a handle bar pipe, and a switch case installed between the left and right handle bar grips and supported by the handle bar pipe, and the optical sensor is installed on the switch case.

An electric vehicle includes front and rear wheels, a battery, an electric motor that drives at least one of the front and rear wheels, an accelerator, and a mode shift operator that is operated by a user in order to switch drive modes. The electric vehicle includes a driving force characteristics setter that sets, for each of the plurality of drive modes, driving force characteristics which are characteristics of an accelerator opening degree and a target motor driving force for the rotational speed of the electric motor. The electric vehicle further includes a controller which shifts up, according to an operation of the mode shift operator, the drive mode from a first drive mode to a second drive mode and which controls the target motor driving force according to the driving force characteristics. When a shift-down prohibition condition is met, the controller prohibits a shift down from the second drive mode to the first drive mode.
