Extend your Cycle-On Pro or Cycle-On to accommodate two additional bikes. And with an optional add–on kit that increases the number of bikes you can carry from 2 up to 4, the Cycle–On rack really can meet your needs for a lifetime. The only thing it can’t do is help you hide the smile on your face as you watch other people struggle to get their bikes on a roof rack. Maybe you should let them in on the Cycle–On secret.
