Separate suspension mounts attach to the core, which permits them to be exchanged for other mounts to provide different suspension geometries. A power electronics unit attaches to the front of the monocoque. The shape of the monocoque allows for the proper positioning of the center of gravity of the motorcycle in order to provide a balanced ride. ## Claims ### Claim 1 A core for an electric motorcycle comprising: a monocoque that defines a mouth, the monocoque dimensioned to enclose a battery pack; a housing for a motor and gear, the housing connected to the monocoque inside the mouth; and fixation points defined in the core for removably attaching one or more suspension mounts. ### Claim 2 (depends on 1) The core according to claim 1, further comprising the one or more suspension mounts removably attached to the core. ### Claim 3 (depends on 2) The core according to claim 2, wherein the suspension mounts include a shock absorber mount and a swingarm mount. ### Claim 4 (depends on 2) The core according to claim 2, wherein the suspension mounts include a shock absorber mount and a combined swingarm and shock absorber link mount. ### Claim 5 (depends on 1) The core according to claim 1, wherein the fixation points are in the monocoque. ### Claim 6 (depends on 1) The core according to claim 1, wherein the fixation points are in the housing for the motor and gear. ### Claim 7 (depends on 1) The core according to claim 1, wherein the fixation points are in the monocoque and the housing for the motor and gear. ### Claim 8 (depends on 1) The core according to claim 1, wherein the monocoque comprises two clamshells. ### Claim 9 (depends on 1) The core according to claim 1, wherein the monocoque comprises two side plates and a wall between the side plates. ### Claim 10 (depends on 1) The core according to claim 1, further comprising a power electronics unit attached to a front side of the monocoque. ### Claim 11 (depends on 1) The core according to claim 1, wherein the monocoque covers a majority of a front, a majority of a top, and a majority of a bottom of the housing for the motor and gear. ### Claim 12 (depends on 1) The core according to claim 1, wherein the monocoque comprises multiple layers that are removably connected together. ### Claim 13 (depends on 1) The core according to claim 1, comprising further fixation points for a headstock. ### Claim 14 (depends on 1) The core according to claim 1, comprising further fixation points for one or more accessories. ### Claim 15 (depends on 1) The core according to claim 1, wherein the monocoque has a C-shape.
