This is not my idea or my house but I thought I would share how it is done at my parents' house. They have the best driveway for grandchildren to ride bikes and trikes on. It is paved, flat, and long with a basketball area so needless to say lots of bikes and trikes stay there ready for grandchildren to visit.
My dad put two hooks up and then hung a metal bar on some chain and there is a great place to store bikes and trikes. I think I counted 10 hanging there.
