Since moving out of my spacious ranch last year, I've moved into a home with a much smaller two car garage. I use inexpensive rubber coated bicycle hooks you get at Home Depot or Lowes. Got a little array of them in the ceiling near the HVAC & HW Htr. in the garage. So, that's good for hanging about three or four bikes. I also installed some pull down stairs to the attic space above garage. Decked off the floor up there. Rigged up a rope & pulley. And, about ten bike hooks. I can easily pull bikes up & down from the attic with the rope & pulley system. I've had up to seven bikes hanging up there. (Only three up there now since I've been selling a lot of my old bikes this summer). Ropes & pulleys can solve a lot of problems in small spaces.
