Hard to tell from the pics but it looks like you might need bikes to horizontal to the ceiling based on ceiling height? Might try and rig up something like this? https://www.floaterhoist.com/ or get fancy and make something like this https://flat-bike-lift.com/ or make your own with hinges and 2x4's

I like this idea https://hideabike.com/ your could add pulleys to your existing hooks DIY style, or buy there system

Edit - could also work for frames - 2 hooks, 1 pulley

Edit 2 -For just frames I might even just strategically screw velcro straps into the ceiling
