Abstract

An electric cycle with a frame that may include a tube and an opening. The tube may extend from a first end to a second end and may define a tube interior volume in fluid communication with the opening. An electric power unit may be mounted to the frame proximal the second end of the tube and may have a cooling air inlet and an exhaust port. A cooling path may be defined through the tube interior volume and at least a portion of the electric power unit. The cooling path may be in fluid communication with the opening so that air may flow into the opening, through the tube, into the cooling air inlet and out of the exhaust port of the electric power unit.
