MOTORCYCLE PARKING IN TUNG CHUNG

Does anyone know about existence of any monthly undercover motorcycle parking space in Tung Chung around the Coastal Skyline La Rossa or the City Gate shopping mall. A real-estate agent told me that the only solution is to rent a car parking space and park bike there, but that would be too costly. Not sure if that is legal at all as land use is strictly allocated and controlled by the HK law. If yes, is it possible to share such space with other bikes? There are no monthly spaces at City Gate, only hourly rate of $11 per hour. The Visionary does not rent parking spaces to non-residents, and the Caribbean Coast has once a year lucky draw in April for few places available there. Any other information is much appreciated.
