Park your bike vertically in a space-efficient manner.
Other than upside down from the ceiling, parking a bike vertically is the most space efficient means. The problem with from the ceiling or vertically with hooks is that you need to lift the entire bike to hang it. That can be difficult for heavier bikes like electrics or for children to lift.
Park your bike fast and get going.
Grab you handlebars and lift the front wheel up so you are rolling on just the back wheel. With the bike vertical, roll the front wheel into the BikeLatch. Hear it click and it is secure. To release, push forward and it will click out and you're ready to go. It is adjustable for different tire widths 1.25" to 3.25". There's a hook for your helmet too.
