The present invention relates in general to the field of water pumps, and more specifically, to an attachment configured to connect to the rear wheel of a motorcycle or motorscooter to provide power to a water pump and a method of pumping water using the attachment. One aspect of the aquacycle pump includes a base plate and a kick-stand support bracket configured to slidably adjust so that the aquacycle pump may be compatible with different sizes of motorcycles or motorscooters. The aquacycle pump may further include a roller that is configured to abut against the rear wheel of the motorcycle or motorscooter. The aquacycle pump may further include a water pump, wherein the water pump is connected to the roller. The aquacycle pump is configured such that as the engine of the motorcycle or motorscooter is started and power is provided to rotate its rear wheel, the abutting roller of the aquacycle pump also rotates. The rotation of the roller, in turn, operates the water pump to convey water to a location where water is needed. The purpose of the invention is to provide a device and method that may utilize existing motorized vehicles prevalent in developing countries (e.g., motorcycles, motorscooters), instead of electricity or petrol generators, to provide energy to a water pump for delivering water.
