This product is delivered disassembled. The installation is not very complicated. Once assembled and made the necessary adjustments to make it suitable for your vehicle it is installed in less than 30 seconds flat. Release is also faster. Only drawback, but it does to me of all bike rack models that could accommodate 3 bikes (and this also may depend on the size of the bike to be installed), you will still need to place a minimum juggle three bikes, even upside down. A protection bar prevents the bikes coming down against the body. Compared to my old bicycle door Decathlon, there is no comparison. Here more straps flying for fear that the bicycle carrier wanders from right to left. The rigid links which it has are a guarantee of security, serenity and bike rack to give practical and effective character.
