Abstract

An electric motorcycle has a battery, an electric motor and an electronic control unit positioned in a receiving space between a main frame and an underframe. The electronic control unit is transversely in line with at least part of the electric motor. A combined width of the electric motor and electronic control unit divided by the maximum frame width is within 0.55-0.75. The maximum main frame width divided by the wheelbase is within 0.08-0.15. The vehicle cover has left and right front half cowls on left and right sides of the head tube, with air cutting outside edges disposed wider than the front shock absorbers and wider than the maximum width of the frame. The battery support system has fixed portions which limit battery movement in five directions and a detachable side strap which limits battery movement in the other sideways direction.

Dependent claims

An electric motorcycle, comprising

a frame comprising a main frame extending longitudinally and an underframe at least partially positioned below the main frame, the main frame and the underframe jointly defining a receiving space between the main frame and the underframe;
a vehicle cover at least partially covering the frame;
wheels comprising a front wheel and a rear wheel with a distance between a front wheel rotational axis and a rear wheel rotational axis being defined as a wheelbase, the wheels supporting the frame through a suspension system;
an electric motor providing torque to at least one of the front wheel or the rear wheel, the electric motor being supported by the frame within the receiving space;
a battery supported by the frame within the receiving space and providing electrical energy for the motor;
and
an electronic control unit for controlling the motor, the electronic control unit being supported by the frame within the receiving space so as to be transversely in line with at least part of the electric motor;
wherein a combined width ratio of a combined width of the electric motor and electronic control unit divided by a maximum width of the frame is greater than or equal to 0.55 and less than or equal to 0.75;
and
wherein a frame width ratio of the maximum width of the main frame divided by the wheelbase is greater than or equal to 0.08 and less than or equal to 0.15.

An electric motorcycle comprising:

a frame comprising a main frame extending longitudinally rearwardly from a head tube and an underframe at least partially positioned below the main frame, the main frame and the underframe jointly defining a receiving space between the main frame and the underframe, the frame having a maximum frame width;
a vehicle cover at least partially covering the frame;
wheels comprising a front wheel and a rear wheel;
a suspension system connected to the wheels and supporting the frame, wherein the suspension system comprises two front shock absorbers connected to the front wheel, the two front shock absorbers being pivotal about a head tube axis for steering of the front wheel;
