Place a stepstool underneath the area of the ceiling where you want to hang your bike, choosing a place that's generally away from the rest of your furniture in the bedroom. This area should at least be 8 inches out from the wall, to reduce scuffing.
Run a studfinder along the ceiling in this designated area. Mark the locations of the studs. Select the location for your bike that keeps it out of the direct flow of traffic in your room. Circle it with chalk.
Drill a 1/4-inch-deep pilot hole in this area. Screw in your bicycle hook directly into this hole. Twist the hook with pliers if screwing it in by hand becomes too difficult.
