This is a self contained motorcycle storage port on wheels. The metal hoops can be removed from the base, so that when not in use, the base can be put on the side and takes up less space. The unit has a heater and with the vents in the heavy vinyl cover, condensation does not occur. The cover attaches to the base with velcro making a tight seal. There is an electrical box on the base for a battery tender. The heavy gauge metal ramp can handle the heaviest bikes.
