I get pairs of vinyl coated hooks from walmart and hang them from BOTH wheels, and yes, alternating which end is "forward" will allow you to pack them in at least as tight as the ceiling joists, no issues. If you buy "bike hooks" they'll be expensive, but the heavy duty vinyl coated hooks at wally world come in at 6 pcs for $2 or something ridiculous, so you can afford to hang them all!
