Motorcycle

A vehicle, e.g., a two-wheeled electric vehicle, is operable in a low-speed mode, in which the vehicle can be propelled selectively in the forward or reverse direction, at a speed limited to approximately an average person's walking speed, e.g., approximately 3 mph. The amount of torque driving the vehicle is controlled so that higher torque is available to propel the vehicle at lower speeds and lower torque is available to propel the vehicle at higher speeds. The maximum torque of the vehicle's electric motor is available to propel the vehicle at a standstill.

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.

Switchgear for vehicle and vehicle including switchgear

A liquid cooled motor enclosure includes a fluid tight space adapted to contain a coolant fluid. A motor is arranged inside the enclosure and is thermally coupled to the inner side of the enclosure. An inlet manifold is located at one axial end of the enclosure, and an outlet manifold is located at the opposite axial end of the enclosure. The cross-sectional areas of the inlet and outlet manifolds are sized and configured to provide for substantially uniform flow of coolant around the entire circumference of the enclosure and/or so that coolant flowing in the space from the inlet manifold toward the outlet manifold is substantially axial. A plurality of projections extend into the space to increase the surface area in contact with the coolant fluid and increase turbulence in the coolant fluid flowing in the space to increase heat transfer from the motor to the inner shell and from the inner shell to the coolant fluid.
