Apart from being able to carry two (2) bikes, it also fits most sizes, frames and shapes, with a wheel ratchet that is padded and straps firmly to the bike, securing your wheels and helping hold the bikes firmly. The padding helps protect the bike from unnecessary and unwanted scratches. The rack is designed in such a way that each bike has its own lock and hitch pin with a pair of keys which secure the bikes. There is a point of attachment of the rack to your vehicle and the rack also prevents the bike from scratching your car. An integrated lever lets you tilt the rack down for cargo access or fold it up for storage, and the low loading height reduces the strain of mounting your bikes for transport. This all comes with a one way well directed and easy installation.
