A core of the electric motorcycle includes a monocoque that partially encloses a housing for a motor and gearbox. 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.

A snowmobile tunnel stop protection system to provide protection to a tunnel from a studded endless track used on a snowmobile. The tunnel includes at least one slot formed into an undersurface of the tunnel. At least one protection rail extends from a first end to a second end and includes a plurality of holes passing through the protection rail. A plurality of fasteners are used to attach the protection rail to the tunnel where each fastener has a first fastener portion that passes through the at least one slot. Each fastener includes the first fastener portion that passes through one of the plurality of holes and a second fastener portion that couples to the corresponding first fastener portion to couple the protection rail to the slot formed in the tunnel.

A main frame has a pair of left and right main rails that respectively include left and right front portions, left and right middle portions, and left and right rear end portions. One end portion of the left main rail and one end portion of the right main rail are connected to each other, whereby a head pipe is formed. A first coupling member is attached to the left and right front portions with a plurality of the first bolts, so that the front portions are coupled to each other. A second coupling member is attached to the left and right middle portions with a plurality of the second bolts, so that the middle portions are coupled to each other. A third coupling member is attached to the left and right rear portions with a plurality of the third bolts, so that the rear portions are coupled to each other.

The present invention relates to a bicycle with connector function and at least a number of subsystems. The bicycle includes a tube assembly including a frame with mutually fixed tube elements and movable tube elements, such as a steering pin and a handlebar, at least a first bicycle cassette, for holding at least a first of the number of subsystems, such as a bicycle control unit, of the bicycle for providing a respective function to the bicycle. The first bicycle cassette is arrangeable in at least a first tube element of the tube assembly, and includes a first cassette contact, including a number of contact poles, that is connectable with the at least first of the number of subsystems internal in the first bicycle cassette. A bicycle also includes a connector for connecting with the first cassette contact of the first bicycle cassette. The bicycle connector includes a first connector contact, including a number of contact poles, for connecting with the first cassette contact, and at least one output contact for connecting with a respective subsystem. The bicycle connector is arrangeable in the respective first tube element of the tube assembly.
