There are numerous bike storage options on the market today from a variety of hooks, pulley systems, etc. Everyone has to find what works for them with the space that they have. If you have the height in your storage area the pulley systems work great because you can get your bikes completely out of the way for the winter months or if space is limited during the summer.
Whatever route you go it has to be easy to use. If it isn’t easy to use you will find yourself looking for an alternative. For kids I also try to store their helmets with their bike so that they do not get misplaced. If it is an easy system for the kids to use as well they will be more likely to put them away.
