Hang as much as you can and take apart the things you aren't using into more packable pieces. Bikes in particular store much nicer with the handlebars inline with the wheel and the pedals off. Alternatively shed size self-storage rentals are ~$40 and you don't need to move around like you would in your studio. Not as accessible maybe, but again you can keep the off-season gear out of the way.
