The bike rack is light weight and can slide around your garage floor if not backed up to a wall or secured to the ground (doesn't come with brackets - you'd have to improvise). It took less than 10 minutes to assemble and holds 3 bikes perfectly (even a tandem). You install the "slots" so you can determine if you want all the bikes on one side or to alternate them. It's a good way for little kids to put their own bikes away. Most other systems required lifting or using techniques that a 5 year old can't handle. My kids can now just roll their bike into the rack instead of dumping it on the garage floor. Over all it has been a great value and solved our bike dog pile issue in the garage. I just ordered another as a gift to a friend.
